I have the following XML file which has the namespace as shown...
I have to change the inner text of XML file but need suggestion how to do it.
My XML file is:
<?xml version="1.0"?>
<Report xmlns="http://schemas.microsoft.com/sqlserver/reporting/2005/01/reportdefinition" xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner">
<buttons>
<workshop1>Google</workshop1>
<workshop1>Yahoo</workshop1>
<url1>www.google.co.uk</url1>
</buttons>
</Report>
I have to change the inner text of second node workshop1 from "Yahoo" to "new".
Do this using XElement.
The "problem" you probably had is due to the namespace this xml has:
XElement xml = getXml(); // get your xml from a service\file\ftp etc..
XNamespace ns = "http://schemas.microsoft.com/sqlserver/reporting/2005/01/reportdefinition";
xml.Descendants(ns + "workshop1").First().Value = "new";
Your output:
<Report xmlns="http://schemas.microsoft.com/sqlserver/reporting/2005/01/reportdefinition" xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner">
<buttons>
<workshop1>new</workshop1>
<url1>www.google.co.uk</url1>
</buttons>
</Report>
For more than one node use this:
XNamespace ns = "http://schemas.microsoft.com/sqlserver/reporting/2005/01/reportdefinition";
var nodes = xml.Descendants(ns + "workshop1").ToList();
nodes[0].Value = "new";
nodes[1].Value = "new2";
// etc....

How can I read the content of the childnotes using Xpath?
I have already tried this:
var xml = new XmlDocument();
xml.Load("server-status.xml");
var ns = new XmlNamespaceManager(xml.NameTable);
ns.AddNamespace("ns", "namespace");
var node = xml.SelectSingleNode("descendant::ns:server[ns:ip-address]", ns)
Console.WriteLine(node.InnerXml)
But I only get a string like this:
<ip-address>127.0.0.50</ip-address><name>Server 1</name><group>DATA</group>
How can I get the values individually?
Xml file:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<server-status xmlns="namespace">
<server>
<ip-address>127.0.0.50</ip-address>
<name>Server 1</name>
<group>DATA</group>
</server>
</server-status>
You're using XML namespaces in XPath correctly.
However, your original XPath,
descendant::ns:server[ns:ip-address]
says to select all ns:server elements with ns:ip-address children.
If you wish to select the ns:ip-address children themselves, instead use
descendant::ns:server/ns:ip-address
Similarly, you could select ns:name or ns:group elements.
While parsing xml by linq to xml, I came across a strange behaviour (atleast to me). Below is the first xml I parsed
`<?xml version="1.0" encoding="UTF-8"?>
<TestRun>
<UnitTestResult testName = "Arun" outcome = "i">
</UnitTestResult>
<UnitTestResult testName = "Arun1" outcome = "i">
</UnitTestResult>
</TestRun>`
My Code looks like
XDocument doc = XDocument.Parse(fileContents);
var result = doc.Descendants("UnitTestResult");
The above works fine. But If my root node contain attributes the same code is not working. What could be the reason. XML sample below
<?xml version="1.0" encoding="UTF-8"?>
<TestRun id="7903b4ff-8706-4379-b9e8-567034b70abb" name="inaambika#INBELW013312A 2016-02-26 16:55:14" runUser="STC\inaambika" xmlns="http://microsoft.com/schemas/VisualStudio/TeamTest/2010">
<UnitTestResult testName = "Arun" outcome = "i">
</UnitTestResult>
<UnitTestResult testName = "Arun1" outcome = "i">
</UnitTestResult>
</TestRun>
XDocument doc = XDocument.Parse(fileContents);
var result = doc.Descendants("UnitTestResult");
This one below is not ordinary attribute, it is default namespace declaration :
xmlns="http://microsoft.com/schemas/VisualStudio/TeamTest/2010"
Having default namespace declared at the root element level, the root element and all descendant elements without prefix (in this case it means all elements in the posted XML) are in that namespace.
You can use XNamespace + element-local-name to reference element in namespace :
XDocument doc = XDocument.Parse(fileContents);
XNamespace d = "http://microsoft.com/schemas/VisualStudio/TeamTest/2010"
var result = doc.Descendants(d+"UnitTestResult");
<?xml version="1.0" encoding="UTF-8"?>
<Root xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Element xsi:Attribute="Test"></Element>
</Root>
I'm trying to read the "xsi:Attribute" attribute; the code is like this:
var doc = XDocument.Load(new StringReader(xmlText));
var node = doc.Root.Descendants().First();
XNamespace myNamespace = "xsi";
var attribute = node.Attributes(myNamespace + "Attribute").First();
It throws a "Sequence contains no elements" exception in the last line. What am I doing wrong?
You need to use the actual namespace, not "xsi", which is just a local lookup within the XML file itself for the real namespace:
XNamespace myNamespace = "http://www.w3.org/2001/XMLSchema-instance";
Try this (I believe its more generic):
XNamespace myNamespace = doc.Root.GetNamespaceOfPrefix("xsi");
how to add Namespace and Declaration to the existing xml.
My XML
<Order>
<child1></child1>
</Order>
Expected
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<Order xmlns="http://a.com/a">
<child1></child>
</Order>
Assuming you're only changing the element namespaces and ignoring any attributes, you can parse this using LINQ to XML and then change every element's qualified name:
var doc = XDocument.Parse(xml);
XNamespace ns = "http://a.com/a";
foreach (var element in doc.Descendants())
{
element.Name = ns + element.Name.LocalName;
}
I have an xml file whose structure goes as under(partial)
<?xml version="1.0" encoding="UTF-8"?>
<TestRun id="ee3838c9-a7e2-4ddf-acb1-58589e39422d" xmlns="http://microsoft.com/schemas/VisualStudio/TeamTest/2010">

As can be make out that, there is a namespace involved
xmlns="http://microsoft.com/schemas/VisualStudio/TeamTest/2010"
Now if I do
string source = #"D:\23_18_43.trx";
XDocument xDoc = XDocument.Load(source);
var xxxx = (from data in xDoc.Descendants("Results")
select data).Descendants("UnitTestResult").ToList();
There is no value coming.
Whereas , if I omit the namespace and do my processing, it works.
How can I proceed without removing the namespace explicitly from the source file? Can it be done programatically?
Thanks
To find a node in XML with a default namespace, you need to still search for that node using the namespace.
Eg.
XNamespace defaultNs = "http://microsoft.com/schemas/VisualStudio/TeamTest/2010";
and then in your "query";
var xxxx = (from data in xDoc.Descendants(defaultNs + "Results")
select data).Descendants(defaultNs +"UnitTestResult").ToList();
