I have an serialized XML file. This shows the relevant part:
I am reading this XML file with this (code snippet):
temp = Path.GetFileNameWithoutExtension(s);
var document = new XmlDocument();
document.Load(s);
var root = document.DocumentElement;
var node = root["ScenarioDescription"];
var text = node?.InnerText;
var ArmyNode = root["ArmyFiles"];
var ArmyText = ArmyNode?.InnerText;
However, ArmyText returns the concatenation of all three strings that make up the ArmyFiles node. I need them as three separate strings. How can I do this?
This code works to read all the strings in the node and place them into a list:
foreach (XmlElement A in ArmyNode)
{
var ArmyTemp = A.InnerText;
ArmyList.Add(ArmyTemp);
}
var ArmyText = ArmyNode?.InnerText;

What I'm trying to do is get data from my XML file which has been merged with two others and selected each venue from that file and try to add the value to a list so I can manipulate it further.
This is one of my XML files
<?xml version="1.0" encoding="utf-8" ?>
<Funrun>
<Venue name="Roker Park">
<Runner charity="Cancer Research">
<Firstname>Roger</Firstname>
<Lastname>Malibu</Lastname>
<Sponsorship>550</Sponsorship>
</Runner>
<Runner charity="Arthritis UK">
<Firstname>Adam</Firstname>
<Lastname>White</Lastname>
<Sponsorship>340</Sponsorship>
</Runner>
</Venue>
</Funrun >
I need to be able to select the venue name and save it to a list. This is what I've got so far:
List<string> VenueNames = new List<string>();
var doc = XDocument.Load("XMLFile1.xml");
var doc2 = XDocument.Load("XMLFile2.xml");
var doc3 = XDocument.Load("XMLFile3.xml");
var combinedUnique = doc.Descendants("Venue")
.Union(doc2.Descendants("Venue"))
.Union(doc3.Descendants("Venue"));
foreach (var venuename in combinedUnique.Elements("Venue"))
{
VenueNames.Add(venuename.Attribute("name").Value));
}
The easiest way I would do it is by including Name and Charity within the XElements they belong to.
What I would recommend you do is first reformat your document so that it looks like this:
<Funrun>
<Venue>
<Name>Roker Park</Name>
<Runner1>
<charity>Cancer Research</charity>
<Firstname>Roger</Firstname>
<Lastname>Malibu</Lastname>
<Sponsorship>550</Sponsorship>
</Runner1>
<Runner2>
<charity>Arthritis UK</charity>
<Firstname>Adam</Firstname>
<Lastname>White</Lastname>
<Sponsorship>340</Sponsorship>
</Runner2>
</Venue>
</Funrun >
Note that you could get even simpler by combining all the elements under "Funrun" (example: "Venue") and just iterate through all of them without having to switch documents.
Next moving over to C#:
List<string> VenueNames = new List<string>();
var doc = XDocument.Load("XMLFile1.xml");
var doc2 = XDocument.Load("XMLFile2.xml");
var doc3 = XDocument.Load("XMLFile3.xml");
foreach (XElement element in doc.Root.Descendants("Venue"))
{
VenueNames.Add(element.Element("Name").Value.ToString());
}
//Copy paste this code for each document you would like to search through, though of course change "doc" to say, "doc2".
So just real quick, what this code will do is it will first open the Root element in the XDocument. It will find Decendants of that element with the name, "Name", and for each of those it will copy its value as a string into your list.
List<string> xmlFilePaths = new List<string>
{
#"Path\\SomeJson.txt",
#"Path\\SomeJson1.txt"
};
var venues = xmlFilePaths.Select(fp => XDocument.Load(fp).Descendants("Venue")?.FirstOrDefault()?.Attribute("name")?.Value).Distinct().ToList();
I'm trying to do the following: load an Xml string into a XDocument object, but when I try to access elements through Descendants method it return nothing when I tried to see the value of inner elements in Visual Studio it does not recognize it as Xml so what is the problem here?
string xml = #"<ArrayOfKeyValueOfstringint xmlns=""http://schemas.microsoft.com/2003/10/Serialization/Arrays"" xmlns:i=""http://www.w3.org/2001/XMLSchema-instance"">
<KeyValueOfstringint>
<Key>crscmprsn_ttlprt1</Key>
<Value>1</Value>
</KeyValueOfstringint>
<KeyValueOfstringint>
<Key>ptntmntrfrm_ttlprt1</Key>
<Value>1</Value>
</KeyValueOfstringint>
</ArrayOfKeyValueOfstringint>";
var xdoc = XDocument.Parse(xml);
IEnumerable<XElement> elements = xdoc.Descendants("KeyValueOfstringint");
var lst = new List<KeyValuePair<string,int>>();
foreach (var item in elements)
{
var k = item.Element("Key").Value;
int v = int.Parse(item.Element("Value").Value);
var kvp = new KeyValuePair<string,int>(k,v);
lst.Add(kvp);
}
You need to specify namespace to get your elements:
var ns = "http://schemas.microsoft.com/2003/10/Serialization/Arrays";
var elements = xdoc.Descendants(ns + "KeyValueOfstringint");

Reading value of an XML node

Closed 8 years ago.
I have created an Xml file with example contents as follows:
<?xml version="1.0" encoding="utf-8"?>
<W-TIBCPTRs>
<W-TIBCPTR>
<TYPTRT>FDR2 R</TYPTRT>
<CLAFCNO VALIDE="NON">5b1</CLAFCNO>
<NUMCLI>0067781</NUMCLI>
<TYPACT>D</TYPACT>
</W-TIBCPTR>
<W-TIBCPTR>
<TYPTRT>FDR2 R</TYPTRT>
<CLAFCNO>511</CLAFCNO>
<NUMCLI>0068078</NUMCLI>
<TYPACT>D</TYPACT>
</W-TIBCPTR>
</W-TIBCPTRs>
i try this
XmlNodeList rowElements = doc.SelectNodes("W-TIBCPTRs/W-TIBCPTR");
foreach (XmlElement rowElement in rowElements)
{
foreach (XmlElement valueElement in rowElement.ChildNodes)
{
strin[] k=valueElement.Name;
}
}
I need to selectNodes automaticly because I can have a xml file with different nodes
Stock childNodes in array, I need these values (TYPTRT,CLAFCNO,NUMCLI,TYPACT)
It's easy to do with Linq to Xml (I suggest to use it instead old XmlDocument API):
var xdoc = XDocument.Load(path_to_xml);
var result = from t in xdoc.Root.Elements("W-TIBCPTR")
select new {
TYPTRT = (string)t.Element("TYPTRT"),
CLAFCNO = (string)t.Element("CLAFCNO"),
NUMCLI = (string)t.Element("NUMCLI"),
TYPACT = (string)t.Element("TYPACT")
};
Result:
[
{
TYPTRT: "FDR2 R",
CLAFCNO: "5b1",
NUMCLI: "0067781",
TYPACT: "D"
},
{
TYPTRT: "FDR2 R",
CLAFCNO: "511",
NUMCLI: "0068078",
TYPACT: "D"
}
]
NOTE: Currently you are selecting element's name. If you want to get inner text of all sub-elements in array, you can use:
string[] items = rowElement.ChildNodes.OfType<XmlElement>()
.Select(e => e.InnerText)
.ToArray();
That will return array of four strings for each W-TIBCPTR element in your sample xml. Same with Linq to Xml will look like:
var result = from t in xdoc.Root.Elements("W-TIBCPTR")
select t.Elements().Select(e => e.Value).ToArray();
Use Linq to XML
var doc= XDocument.Load(<path>);
var values = from c in doc.Descendants("W-TIBCPTR")
select new
{
TYPTRT = c.Element("TYPTRT").Value,
CLAFCNO = c.Element("CLAFCNO").Value
NUMCLI = c.Element("NUMCLI").Value
TYPACT = c.Element("TYPACT").Value
});
I'm parsing a lot of XML files using Linq to XML synatx, everything works when I try to access top level elements
var indexroot = (from element in prodcutDocument.Root.Descendants("indexroot")
select new
{
model = (string)element.Element("MODEL"),
}).FirstOrDefault()
The problem occurs when I need to access lower level childs of that document I tried:
var indexroot = (from element in prodcutDocument.Root.Descendants("indexroot")
select new
{
ddName = (string)element.Descendants("DD_NAME").Elements("name").First();
}).FirstOrDefault()
and
var indexroot = (from element in prodcutDocument.Root.Descendants("indexroot").Descendants("DD_NAME")
select new
{
ddName = (string)element.Element("name")
}).FirstOrDefault();
Sadly none of that works and i get same error "Sequence contains no elements". And one more thing sometimes the XML document contains those tags and sometimes not is something like this enough for handling this case?
var indexroot = (from element in prodcutDocument.Root.Descendants("indexroot").Descendants("DD_NAME")
select new
{
ddName = (string)element.Element("name") ?? "-"
}).FirstOrDefault();
Edit:
I don't think is possible to paste short version of XML that would be simple, so here's full version: http://pastebin.com/uDkP3rnR and for the code example:
XDocument prodcutDocument = XDocument.Load(this.ServerPATHData + file);
var indexroot = (from element in prodcutDocument.Root.Descendants("indexroot")
select new
{
modelis = (string)element.Element("MODELIS"),
T2918_0 = (string)element.Descendants("dd_DARBINIS_GRAFIKAS_SPEC").First()
}).FirstOrDefault();
writeTxt.WriteLine("modelis: " + indexroot.modelis);
writeTxt.WriteLine("T2979_0" + indexroot.T2918_0);
In examining the sample XML that you posted on PasteBin, it appears to me that the elements that you mention appear only once. To access them, you can simply specify a path to each as follows:
XElement indexroot = document.Root.Element("indexroot");
XElement modelis = indexroot.Element("MODELIS");
XElement dd_dgs = indexroot.Element("dd_DARBINIS_GRAFIKAS_SPEC");
XElement voltageuv = dd_dgs.Element("VoltageUV");
string t2979_0 = (string)voltageuv.Element("T2979_0");
string t2861_60 = (string)voltageuv.Element("T2861_60");
string t2757_121 = (string)voltageuv.Element("T2757_121");
(Note that you may need to check for null if there is a chance that any of the elements you are trying to access may not be present. Without doing so, you'll encounter a NullReferenceException.)
Here is a snippet of the XML that you posted to give context to the above code:
<?xml version='1.0' encoding='UTF-8' standalone='no'?>
<PDB>
<indexroot>
<ed_BENDRA_MAKS_SUV_GALIA>1.45</ed_BENDRA_MAKS_SUV_GALIA>
<ed_BENDRA_MAKS_SROVE>6.48</ed_BENDRA_MAKS_SROVE>
<TIPAS>1</TIPAS>
<MODELIS>RIS 2500 HW EC 3.0</MODELIS>
<dd_DARBINIS_GRAFIKAS_SPEC>
<VoltageUV>
<T2979_0>229,42</T2979_0>
<T2861_60>227,98</T2861_60>
<T2757_121>228,97</T2757_121>
</VoltageUV>
<CurrentIA>
<T2979_0>2,56</T2979_0>
<T2861_60>2,63</T2861_60>
<T2757_121>2,72</T2757_121>
</CurrentIA>
</dd_DARBINIS_GRAFIKAS_SPEC>
</indexroot>
</PDB>
You can just change:
element.Descendants("dd_DARBINIS_GRAFIKAS_SPEC").First()
to this:
element.Descendants("dd_DARBINIS_GRAFIKAS_SPEC").FirstOrDefault() ?? "-"
I want to replace a node with a new node. How can I get the exact position of the node and do a complete replace?
I've tried the following, but I can't figured out how to get the index of the node or which parent node to call ReplaceChild() on.
string html = "<b>bold_one</b><strong>strong</strong><b>bold_two</b>";
HtmlDocument document = new HtmlDocument();
document.LoadHtml(html);
var bolds = document.DocumentNode.Descendants().Where(item => item.Name == "b");
foreach (var item in bolds)
{
string newNodeHtml = GenerateNewNodeHtml();
HtmlNode newNode = new HtmlNode(HtmlNodeType.Text, document, ?);
item.ParentNode.ReplaceChild( )
}
To create a new node, use the HtmlNode.CreateNode() factory method, do not use the constructor directly.
This code should work out for you:
var htmlStr = "<b>bold_one</b><strong>strong</strong><b>bold_two</b>";
var doc = new HtmlDocument();
doc.LoadHtml(htmlStr);
var query = doc.DocumentNode.Descendants("b");
foreach (var item in query.ToList())
{
var newNodeStr = "<foo>bar</foo>";
var newNode = HtmlNode.CreateNode(newNodeStr);
item.ParentNode.ReplaceChild(newNode, item);
}
Note that we need to call ToList() on the query, we will be modifying the document so it would fail if we don't.
If you wish to replace with this string:
"some text <b>node</b> <strong>another node</strong>"
The problem is that it is no longer a single node but a series of nodes. You can parse it fine using HtmlNode.CreateNode() but in the end, you're only referencing the first node of the sequence. You would need to replace using the parent node.
var htmlStr = "<b>bold_one</b><strong>strong</strong><b>bold_two</b>";
var doc = new HtmlDocument();
doc.LoadHtml(htmlStr);
var query = doc.DocumentNode.Descendants("b");
foreach (var item in query.ToList())
{
var newNodesStr = "some text <b>node</b> <strong>another node</strong>";
var newHeadNode = HtmlNode.CreateNode(newNodesStr);
item.ParentNode.ReplaceChild(newHeadNode.ParentNode, item);
}
Have Implemented the following solution to achieve the same.
var htmlStr = "<b>bold_one</b><div class='LatestLayout'><div class='olddiv'><strong>strong</strong></div></div><b>bold_two</b>";
var htmlDoc = new HtmlDocument();
HtmlDocument document = new HtmlDocument();
document.Load(htmlStr);
htmlDoc.DocumentNode.SelectSingleNode("//div[#class='olddiv']").Remove();
htmlDoc.DocumentNode.SelectSingleNode("//div[#class='LatestLayout']").PrependChild(newChild)
htmlDoc.Save(FilePath); // FilePath .html file with full path if need to save file.
so selecting an object and removing respective HTML object
and appending it as chile. of respective object.
