I am trying to add a custom XML part to Word. What I am doing is I have generated an XML model that binds all my data in the Word file. This is how I am trying to fill it, but nothing is being added:
public void FeedCustomXmlParts(MyModel model, string xmlns)
{
var ser = new XmlSerializer(typeof(MyModel), xmlns);
using (var ms = new MemoryStream())
{
ser.Serialize(ms, model);
CustomXmlPart partLabel = GetCustomXmlPart(_wordDoc.MainDocumentPart, xmlns);
ms.Position = 0;
partLabel.FeedData(ms);
ms.Flush();
}
}
private static CustomXmlPart GetCustomXmlPart(MainDocumentPart mainDocumentPart, string targetNs)
{
if (mainDocumentPart == null)
{
throw new ArgumentNullException(nameof(mainDocumentPart));
}
return (from part in mainDocumentPart.CustomXmlParts
let xElement = part.GetXDocument().Root
where xElement != null
let ns = xElement.GetDefaultNamespace()
where ns == targetNs
select part).FirstOrDefault();
}
What am I doing wrong?
According to your description, I understand that you want to add custom XML parts to the word.
The following code example adds a custom XML part to a specified document.
private void AddCustomXmlPartToActiveDocument(Word.Document document)
{
string xmlString =
"<?xml version=\"1.0\" encoding=\"utf-8\" ?>" +
"<employees xmlns=\"http://schemas.microsoft.com/vsto/samples\">" +
"<employee>" +
"<name>Karina Leal</name>" +
"<hireDate>1999-04-01</hireDate>" +
"<title>Manager</title>" +
"</employee>" +
"</employees>";
Office.CustomXMLPart employeeXMLPart = document.CustomXMLParts.Add(xmlString, missing);
}
For more information, please refer to:To add a custom XML part to a Word document
Hope that helps!

I'm doing some file clean up in an xml file and trying to use string.Replace to replace certain text blocks but it does not seem to be replacing the text that I am searching on.
My clean up code is follows
private Stream PrepareFile(string path)
{
string data = File.ReadAllText(path);
var newData = data.Replace("<a:FMax xmlns:b=\"http://www.w3.org/2001/XMLSchema\" i:type=\"b:string\"/>", "<a:FMax>0</a:FMax>")
.Replace("<a:KVy xmlns:b=\"http://www.w3.org/2001/XMLSchema\" i:type=\"b:string\"/>", "<a:KVy>0</a:KVy>")
.Replace("<a:Td xmlns:b=\"http://www.w3.org/2001/XMLSchema\" i:type=\"b:string\"/>", "<a:Td>0</a:Td>")
.Replace("<a:VyLim xmlns:b=\"http://www.w3.org/2001/XMLSchema\" i:type=\"b:string\"/>", "<a:VyLim>0</a:VyLim>");
var newData2 = newData.Replace("<a:VxTableSxI3_2I xmlns:b=\"http://www.w3.org/2001/XMLSchema\" i:type=\"b:string\"/>", "<a:VxTableSxI3_2I>0</a:VxTableSxI3_2I>");
byte[] bytes = Encoding.ASCII.GetBytes(newData2);
return new MemoryStream(bytes);
}
I should be able to write back to the original 'data' variable, but I split the variables out to be able to compare the strings before and after the replace. My xml file contains the following values(copied verbatim)
<a:LongitudinalTracker z:Id="i58">
<Name xmlns="http://schemas.datacontract.org/2004/07/HmsSim.EntityModule.BaseTypes" i:nil="true"/>
<a:FMax xmlns:b="http://www.w3.org/2001/XMLSchema" i:type="b:string"/>
<a:K>2</a:K>
<a:KVy xmlns:b="http://www.w3.org/2001/XMLSchema" i:type="b:string"/>
<a:Td xmlns:b="http://www.w3.org/2001/XMLSchema" i:type="b:string"/>
<a:VyLim xmlns:b="http://www.w3.org/2001/XMLSchema" i:type="b:string"/>
</a:LongitudinalTracker>
And the before and after strings look identical. I'm sure I am missing something silly, but I can't see what it is. Most of the answers to similar questions point out that the original code is not using the return value, but in this case I am definitely using the return value.
As suggested I am posting the code that ended up solving this.
private Stream PrepareFile(string path)
{
string data = File.ReadAllText(path);
var xml = XDocument.Parse(data);
XNamespace ns = "http://schemas.datacontract.org/2004/07/HmsSim.EntityModule.Entities.SimulationEntities.Track";
var longTracker = from item in xml.Descendants(ns + "LongitudinalTracker") select item;
foreach (var xElement in longTracker.Elements())
{
XNamespace nsI = "http://www.w3.org/2001/XMLSchema-instance";
if (xElement.Attribute(nsI + "type") != null)
{
xElement.Attribute(nsI + "type").Remove();
XAttribute attribute = new XAttribute(nsI + "nil", "true");
xElement.Add(attribute);
}
}
var latTracker = from item in xml.Descendants(ns + "LateralTracker") select item;
foreach (var xElement in latTracker.Elements())
{
XNamespace nsI = "http://www.w3.org/2001/XMLSchema-instance";
if (xElement.Attribute(nsI + "type") != null)
{
xElement.Attribute(nsI + "type").Remove();
XAttribute attribute = new XAttribute(nsI + "nil", "true");
xElement.Add(attribute);
}
}
Stream stream = new MemoryStream();
xml.Save(stream);
// Rewind the stream ready to read from it elsewhere
stream.Position = 0;
return stream;
}
This code works and is less brittle than the original code. As always, suggestions are welcome. Thanks to everyone who commented and led me towards this answer, I appreciate it.
I am trying append a serialized object to an existing xml file beneath the root element, which I thought would be simple but is proving to be a little challenging.
The problem is in the AddShortcut method but I added some more code for completeness.
I believe what I need to do is:
load the file into an XmlDocument.
navigate to the node I want to append beneath (here the node name is Shortcuts).
create some type of writer and then serialize the object.
save the XmlDocument.
The trouble is in steps 2 and 3. I have tried different variations but I think using XPathNavigator somehow to find the "root" node to append under is a step in the right direction.
I have also looked at almost every question on Stack Overflow on the subject.
Any suggestions welcome. Here is my code
class XmlEngine
{
public string FullPath { get; set; } // the full path to the xmlDocument
private readonly XmlDocument xDoc;
public XmlEngine(string fullPath, string startElement, string[] rElements)
{
FullPath = fullPath;
xDoc = new XmlDocument();
CreateXmlFile(FullPath, startElement, rElements);
}
public void CreateXmlFile(string path, string startElement, string[] rElements)
{
try
{
if (!File.Exists(path))
{
// create a txt writer
XmlTextWriter wtr = new XmlTextWriter(path, System.Text.Encoding.UTF8);
// make sure the file is well formatted
wtr.Formatting = Formatting.Indented;
wtr.WriteProcessingInstruction("xml", "version='1.0' encoding='UTF-8'");
wtr.WriteStartElement(startElement);
wtr.Close();
// write the top level root elements
writeRootElements(path, rElements);
}
}
catch (Exception ex)
{
Console.WriteLine("Error: " + ex.Message);
Console.WriteLine("Could not create file: " + path);
}
}
public void AddShortcut(Shortcut s)
{
xDoc.Load(FullPath);
rootNode = xDoc.AppendChild(xDoc.CreateElement("Shortcuts"));
var serializer = new XmlSerializer(s.GetType());
using (var writer = new StreamWriter(FullPath, true))
{
XmlWriterSettings ws = new XmlWriterSettings();
ws.OmitXmlDeclaration = true;
serializer.Serialize(writer, s);
}
xDoc.Save(FullPath);
}
}
This code sample worked for me:
xml:
<?xml version="1.0" encoding="UTF-8"?>
<Launchpad>
<Shortcuts>
<Shortcut Id="1">
<Type>Folder</Type>
<FullPath>C:\SomePath</FullPath>
<Name>SomeFolderName</Name>
</Shortcut>
</Shortcuts>
</Launchpad>
Method:
public void AddShortcut(Shortcut s)
{
xDoc.Load(FullPath);
var rootNode = xDoc.GetElementsByTagName("Shortcuts")[0];
var nav = rootNode.CreateNavigator();
var emptyNamepsaces = new XmlSerializerNamespaces(new[] {
XmlQualifiedName.Empty
});
using (var writer = nav.AppendChild())
{
var serializer = new XmlSerializer(s.GetType());
writer.WriteWhitespace("");
serializer.Serialize(writer, s, emptyNamepsaces);
writer.Close();
}
xDoc.Save(FullPath);
}
load the file into an XmlDocument.
navigate to the node I want to append beneath (here the node name is Shortcuts).
create some type of writer and then serialize the object.
save the XmlDocument
So:
public void AddShortcut(Shortcut s)
{
// 1. load existing xml
xDoc.Load(FullPath);
// 2. create an XML node from object
XmlElement node = SerializeToXmlElement(s);
// 3. append that node to Shortcuts node under XML root
var shortcutsNode = xDoc.CreateElement("Shortcuts")
shortcutsNode.AppendChild(node);
xDoc.DocumentElement.AppendChild(shortcutsNode);
// 4. save changes
xDoc.Save(FullPath);
}
public static XmlElement SerializeToXmlElement(object o)
{
XmlDocument doc = new XmlDocument();
using(XmlWriter writer = doc.CreateNavigator().AppendChild())
{
new XmlSerializer(o.GetType()).Serialize(writer, o);
}
return doc.DocumentElement;
}

I have a method which load XML to a XDocument and modify its elements then save.
But when I reload it. I got this error :
Unexpected XML declaration. The XML declaration must be the first node in the document, and no white space characters are allowed to appear before it.
I checking the XML and see that the XDocument didn't save the changed but create a duplicate and save.
It save the old one and the new one like this example xml :
<?xml version="1.0" encoding="UTF-8"?>
<Ungdungs>
<Ungdung>
<Name>HERE City Lens</Name>
<Id>b0a0ac22-cf9e-45ba-8120-815450e2fd71</Id>
<Path>/Icon/herecitylens.png</Path>

<?xml version="1.0" encoding="UTF-8"?>

<Path>/Icon/herecitylens.png</Path>
<Version>1.0.0.0</Version>
<Category>HERE</Category>
<Date>Uknown</Date>
</Ungdung>
Here the code I used to modify and save XML :
using (Stream stream = storage.OpenFile("APPSDATA.xml", FileMode.Open, FileAccess.ReadWrite))
{
//var xdoc = XDocument.Load("APPSDATA.xml");
var xdoc = XDocument.Load(stream, LoadOptions.None);
var listapp = from c in xdoc.Descendants("Ungdung") select c;
foreach (XElement app in listapp)
{
var xElement = app.Element("Name");
if (xElement != null)
progressIndicator.Text = "Checking " + xElement.Value + "...";
var element = app.Element("Id");
if (element != null)
{
var appId = element.Value;
var appVersion = await GetAppsVersion(appId);
app.Element("Version").Value = appVersion.ToString();
}
}
xdoc.Save(stream);
}
How can I solve this problem ?
Looks like you're appending modified document at the end of current file content. That's why you can't parse it later again.
I would split read and write parts into different using statements:
XDocument xdoc;
using (Stream stream = storage.OpenFile("APPSDATA.xml", FileMode.Open, FileAccess.Read))
{
xdoc = XDocument.Load(stream, LoadOptions.None);
}
var listapp = from c in xdoc.Descendants("Ungdung") select c;
foreach (XElement app in listapp)
{
var xElement = app.Element("Name");
if (xElement != null)
progressIndicator.Text = "Checking " + xElement.Value + "...";
var element = app.Element("Id");
if (element != null)
{
var appId = element.Value;
var appVersion = await GetAppsVersion(appId);
app.Element("Version").Value = appVersion.ToString();
}
}
using (Stream stream = storage.OpenFile("APPSDATA.xml", FileMode.Truncate, FileAccess.Write))
{
xdoc.Save(stream);
}
Setting FileMode.Truncate on second using statement will clear previous file content, what should fix your problem.
<CPT xmlns="http://www.example.org/genericClientProfile" xmlns:ns2="http://www.blahblah.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.example.org/genericClientProfile genericClientProfile.xsd">
<header>
<serviceId>CPT-UK</serviceId>
<versionId>1.0</versionId>
<brandCode>CUK</brandCode>
<creationTime>2013-09-26T13:55:32.31+02:00</creationTime>
</header>
</CPT>
I need to be able to read the elements in the header tag. I'm struggling to read the values for some reason, which i'm not sure of. What i've tried:
public ActionResult readxmldata()
{
using (var db = new CPTEntities())
{
var file = System.IO.Directory.GetFiles("C:\\Workspace\\CPTStaging","*.xml");
foreach (var xmldoc in file)
{
XmlDocument docpath = new XmlDocument();
docpath.Load(xmldoc);
CPTPROFILE doc = new CPTPROFILE();
db.SaveChanges();
H_HEADER header = new H_HEADER();
header.SERVICEID = docpath.SelectSingleNode("//CPT/header/#serviceId").Value;
header.VERSIONID = Convert.ToDecimal(docpath.SelectSingleNode("//CPT/header/#versionId").Value);
header.CREATIONTIME = Convert.ToDateTime(docpath.SelectSingleNode("//CPT/header/#creationTime").Value);
header.BRANDCODE = docpath.SelectSingleNode("//CPT/header/#brandCode").Value;
db.CPTPROFILEs.AddObject(doc);
db.SaveChanges();
}
}
Your XML uses namespaces. xmlns attribute declares default namespace. You should use it for each element of the XML.
XNamespace ns = "http://www.example.org/genericClientProfile";
XDocument doc = XDocument.Load(xmldoc);
XElement header = doc.Root.Element(ns + "header");
For comparison, here is one way to do it with Linq-to-XML:
XDocument doc = XDocument.Load(xmlFileName);
XNamespace ns = "http://www.example.org/genericClientProfile";
var header = doc.Descendants(ns+"header").Single();
H_HEADER header = new H_HEADER();
header.SERVICEID = (string) header.Element(ns + "serviceId");
header.VERSIONID = (double) header.Element(ns + "versionId");
header.BRANDCODE = (string) header.Element(ns + "brandCode");
header.CREATIONTIME = (DateTime) header.Element(ns + "creationTime");
I'm attempting to display XML content tags from a word document that the user uploads, but I'm not sure how to explicitly pull out the data, and then display it as a string.
I think the below SHOULD find the correct descendent (or element, either should work right?) and then allow me to create a string out of it and display it, but I can't get the file to recognise xdoc). What I'm trying to return is located as "w.tag" in the bottom section of code.
Any ideas?
WordprocessingDocument _TempDoc = WordprocessingDocument.Open(Server.MapPath("~/") + filename, true);
//query to find particular descendants
var lv1s = from lv1 in xdoc.Descendants("table")
select new
{
Header = lv1.Attribute("name").Value,
Children = lv1.Descendants("tag")
};
//Loop through results
StringBuilder result = new StringBuilder();
foreach (var lv1 in lv1s)
{
result.AppendLine(lv1.Header);
foreach (var lv2 in lv1.Children)
result.AppendLine(" " + lv2.Attribute("name").Value);
}
//the label should contain the content controls of the document, using the class, XMLfromDocument
labelContentControls.Text = fileUpload_Displayx(XMLfromDocument.GetContentControls(_TempDoc));
public static XDocument GetXDocument(this OpenXmlPart part)
{
XDocument xdoc = part.Annotation<XDocument>();
if (xdoc != null)
return xdoc;
using (Stream str = part.GetStream())
using (StreamReader streamReader = new StreamReader(str))
using (XmlReader xr = XmlReader.Create(streamReader))
xdoc = XDocument.Load(xr);
part.AddAnnotation(xdoc);
return xdoc;
}
//following method gets the structure of the content controls / XML in the document
public static XElement GetContentControls( WordprocessingDocument document)
{
XElement contentControls = new XElement("ContentControls",
document
.MainDocumentPart
.GetXDocument()
.Root
.Element(W.body)
.Elements(W.sdt)
.Select(tableContentControl =>
new XElement("Table",
new XAttribute("Name", (string)tableContentControl
.Element(W.sdtPr).Element(W.tag).Attribute(
W.val)),
tableContentControl
.Descendants(W.sdt)
.Select(fieldContentControl =>
new XElement("Field",
new XAttribute("Name",
(string)fieldContentControl
.Element(W.sdtPr)
.Element(W.tag)
.Attribute(W.val)
)
)
)
)
)
);
// you cannot access the inner XML of the elemnt directly, you must concatenate to the child elements.
// string contentTitle = string.Concat(W.sdtPr);
//return W.tag;
return contentControls;
