When I do
XPathSelectElement("/root/title").ToString()
I get for example <title>this is an <strong>example</strong></title>. But I don't want to get <title> around the text.
When I do
XPathSelectElement("/root/title").Value
then it gets only the text without <strong></strong>
How can I solve this?
From memory:
XPathSelectElement("/root/title/text()").ToString()
Alternatively, you might select all child nodes (/root/title/*) and join the their string representations
You can create an XmlReader and read the inner xml from it.
XElement element = doc.XPathSelectElement("/root/title");
XmlReader reader = element.CreateReader();
reader.MoveToContent();
string innerXml = reader.ReadInnerXml();

I have a problem where I need to get the value of a specific node in c#
I have this sample XML-Code and here is my C# code
string xml = #"
<ChapterHeader>
<Text> I need to get the text here</Text>
</ChapterHeader>
";
XmlReader rdr = XmlReader.Create(new System.IO.StringReader(xml));
while (rdr.Read())
{
if (rdr.NodeType == XmlNodeType.Element)
{
Console.WriteLine(rdr.LocalName);
if (rdr.LocalName == "ChapterHeader")
{
Console.WriteLine(rdr.Value);
}
}
}
The desired output is
<Text> I need to get the text here</Text>
including the Text Node. How can i do that? thank you
I also need to loop a huge xml file
and I need to get the value of a specific node
and I need to skip some specific node also.
example I have a node. the program must not read that Node and its childen Node.
How can i do that?
<ChapterHeader>
<Text> I need to get the text here</Text>
</ChapterHeader>
<Blank>
<Not>
</Not>
</Blank>
The desired output is
<Text> I need to get the text here</Text>
Look for ReadInnerXml which reads all the content, including markup, as a string.
Console.WriteLine( rdr.ReadInnerXml());
In the following question, you want to deal with larger Xml. I prefer Linq to Xml when dealing with larger set.
The program must not read that Node and its childen Node
Yes, it is possible. You could do something like this.
XDocument doc = XDocument.Load("filepath");
var nestedElementValues =
doc.Descendants("ChapterHeader") // flattens hierarchy and look for specific name.
.Elements() // Get elements for found element
.Select(x=>(string)x.Value); // Read the value.
Check this Example
System.Xml.Linq is a newer library designed to get rid of undesired reader style.
var document = XDocument.Parse(xml);
var texts = document.Descendants("Text");
foreach (var text in texts)
{
Console.WriteLine(text);
}
You can use the same parsing style you're using (rdr.LocalName = "Text") and then use rdr.ReadOuterXml()
I need to convert to string a subset of OuterXml content of a XmlElement as in the following example.
Imagine I have an XmlElement object representing the some-element tag
<some-element attribute="value">
<inner-element>
text content
</inner-element>
</some-element>
What's the best approach to get a string that is just <some-element attribute="value">?
If possible, I'd prefer a solution without regular expressions involved, but using DOM classes
You can get the full XML of the element(which includes the close tag) by shallow cloning the node and then grabbing the outer XML of the node:
var xml = #"<some-element attribute=""value"">
<inner-element>
text content
</inner-element>
</some-element>";
XmlDocument doc = new XmlDocument();
doc.LoadXml(xml);
MessageBox.Show(doc.DocumentElement.CloneNode(false).OuterXml);
I think after that point you will have to do some string manipulation to get exactly what you want, but that is relatively easy:
var outer = doc.DocumentElement.CloneNode(false).OuterXml;
var final = outer.Substring(0, outer.LastIndexOf(">", outer.Length - 2)+1);
MessageBox.Show(final);
I finally solved it by creating a temporary XElement instead using LINQ
IEnumerable<XAttribute> attributes = (from XmlAttribute xmlAttribute in node.Attributes select new XAttribute(xmlAttribute.Name, xmlAttribute.Value));
var xElement = new XElement(node.Name, attributes);
return xElement.ToString();
I have an xmldocument that i'm loading xml in to.
The xml looks like this:
<Table1>
<buyer_id>0</buyer_id>
<buyername>CompanyA</buyername>
<address1>123 Simpsons Dr.</address1>
<address2/>
<city>Springfield</city>
<state>ST</state>
<postalcode>12345</postalcode>
<eaddress/>
<phone/>
<fax/>
</Table1>
I'm looping through looking at each CompanyA entry and setting innertext accordingly. I'm using the following code to insert inner text into elements that meet the criteria:
XmlDocument dom = new XmlDocument();
dom.LoadXml(xmlString);
XmlNodeList elemList = dom.GetElementByTagName("Table1");
for(int i = 0; i < elemList.Count; i++)
{
if(dom.GetElementsByTagName("buyername").Item(i).InnerText.Contains("CompanyA")
{
dom.GetElementsByTagName("address1").Item(i).InnerText = "SomeInfo";
}
}
Using the above code, the value of address1(123 Simpsons Dr.) would be replaced by "SomeInfo". I would like to instead insert "SomeInfo" into the address2 element but when I try using:
dom.GetElementsByTagName("address2").Item(i).InnerText = "SomeInfo";
I get an error. I'm able to insert innertext into any element that already has a value but I cannot when the element is empty (such as <address2/>). Thoughts?
Use LINQ2XML.It's a complete replacement to other XML api's like the dirty old idiot XmlDocument
XElement doc=XElement.Load("yourXml.xml");
foreach(var elm in doc.Descendants("Table1"))
{
if(elm.Element("buyername").Value=="CompanyA")
elm.Element("address2").Value="SomeInfo";
}
doc.Save("yourXml.xml");
Check if the address2 xml tag is empty.
If yes , go to its parent and remove the tag then again add the same tag with value.
If no , assign the inner text to address2.
let me know if you need the code.
Use the SetElementValue method in LINQ to XML:
XDocument doc = XDocument.Load(FilePath); //replace with xml file path
IEnumerable<XElement> buyersList = doc.Descendants("Table1"); //get the table node.
var ele = (from buyer in buyersList
where buyer.Element("buyername").Value == "CompanyA"
select buyer).SingleOrDefault();
ele.SetElementValue("address1", "SomeInfo");
ele.SetElementValue("address2", "SomeInfo");
doc.Save(FilePath);
DEMO: http://ideone.com/Cf7YI
I have an Xml document in which some of the elements look like this:
<rootNode attib1="qwerty" >
<subNode1>W</subNode1>
<subNode2>X</subNode2>
<subNode3>Y</subNode3>
<subNode4>Z</subNode4>
ABC
</rootNode>
My objective is to get "ABC" out of the above example. I tried looking at the InnerText (which returns "WXYZABC") and InnerXml and Value (which returns null) properties in the XmlElement class and bunch of properties in the XmlReader class too. Somehow I don't see an elegant way to extract the data I need.
Can someone please help me out?
Thanks in advance.
Have a go with this one:
string xml = #"<rootNode attib1=""qwerty"" >
<subNode1>W</subNode1>
<subNode2>X</subNode2>
<subNode3>Y</subNode3>
<subNode4>Z</subNode4>
ABC
</rootNode>";
var xElement = XElement.Parse(xml);
xElement.Elements().Remove();
xElement.Value.Dump();
What it does is remove all the known Elements and that leaves you with the text you are looking for.
Based on the excellent suggestion from #djechelon, I seem to have found a solution to this:
XmlDocument xdoc = new XmlDocument();
xdoc.Load(#"D:\Test.xml");
XmlElement xmlElement = xdoc.DocumentElement;
foreach (XmlNode node in xmlElement.ChildNodes)
if (node.NodeType == XmlNodeType.Text
&& !string.IsNullOrWhiteSpace(node.Value))
Console.WriteLine(node.Value.Trim());
The above uses the simple fact that the inner text is also an XmlNode as part of the ChildNodes collection of the XmlElement.
Thanks everyone for the great responses!
Try XmlElement.Value
Edit: This is the wrong approach as this will always return NULL on an element node.
I have a basic xml file that looks like this.
<root>
<item>
<title><p>some title</p></title>
</item>
...
</root>
What I want, is to get the whole title string including the html tag of the xml using linq and displaying it in a repeater .
I can get the title with no problem, but the <p> tag is being stripped out.
If I use
title = item.Element("title").ToString(), it works somehow but I get all the xml tag as well - meaning the title is not displayed in html.
I already tried with encoding the "<" with "<" but to do this makes the xml hard to read.
What would be a possible solution besides using CDATA and encoding?
Cheers

Create a reader from the title element and read InnerXml:
static void Main(string[] args)
{
string xml = "<root><item><title><p>some title</p></title></item></root>";
XDocument xdoc = XDocument.Parse(xml);
XElement te = xdoc.Descendants("title").First();
using (XmlReader reader = te.CreateReader())
{
if (reader.Read())
title = reader.ReadInnerXml();
}
}
See Best way to get InnerXml of an XElement? for some ideas on how to get the "InnerXml" of an XElement.
XElement x = XElement.Parse(your xml);
var y= x.Descendants("title").Descendants();
Then iterate y for a list of the contents of the title elements.
BTW, LINQPad (http://www.linqpad.net) is a handy free tool for trying out LINQ-XML.
