XML string for an XML document

Question

I have a whole XML document in String that I need to convert to an XML document and parse the tags in the document

Answer 1

This sample code is taken from csharp-examples.net , written by Jan Slama :

To find nodes in an XML file, you can use XPath expressions. The XmlNode.SelectNodes method returns a list of nodes selected by the XPath string. The XmlNode.SelectSingleNode method finds the first node that matches the XPath string.

XML:

<Names> <Name> <FirstName>John</FirstName> <LastName>Smith</LastName> </Name> <Name> <FirstName>James</FirstName> <LastName>White</LastName> </Name> </Names> 

CODE:

 XmlDocument xml = new XmlDocument(); xml.LoadXml(myXmlString); // suppose that myXmlString contains "<Names>...</Names>" XmlNodeList xnList = xml.SelectNodes("/Names/Name"); foreach (XmlNode xn in xnList) { string firstName = xn["FirstName"].InnerText; string lastName = xn["LastName"].InnerText; Console.WriteLine("Name: {0} {1}", firstName, lastName); } 

Answer 2

Using Linq to xml

Add a link to System.Xml.Linq

and use

 XDocument.Parse(string xmlString) 

Edit: The sample follows the xml data (TestConfig.xml) ..

 <?xml version="1.0"?> <Tests> <Test TestId="0001" TestType="CMD"> <Name>Convert number to string</Name> <CommandLine>Examp1.EXE</CommandLine> <Input>1</Input> <Output>One</Output> </Test> <Test TestId="0002" TestType="CMD"> <Name>Find succeeding characters</Name> <CommandLine>Examp2.EXE</CommandLine> <Input>abc</Input> <Output>def</Output> </Test> <Test TestId="0003" TestType="GUI"> <Name>Convert multiple numbers to strings</Name> <CommandLine>Examp2.EXE /Verbose</CommandLine> <Input>123</Input> <Output>One Two Three</Output> </Test> <Test TestId="0004" TestType="GUI"> <Name>Find correlated key</Name> <CommandLine>Examp3.EXE</CommandLine> <Input>a1</Input> <Output>b1</Output> </Test> <Test TestId="0005" TestType="GUI"> <Name>Count characters</Name> <CommandLine>FinalExamp.EXE</CommandLine> <Input>This is a test</Input> <Output>14</Output> </Test> <Test TestId="0006" TestType="GUI"> <Name>Another Test</Name> <CommandLine>Examp2.EXE</CommandLine> <Input>Test Input</Input> <Output>10</Output> </Test> </Tests> 

Using C # ...

 XElement root = XElement.Load("TestConfig.xml"); IEnumerable<XElement> tests = from el in root.Elements("Test") where (string)el.Element("CommandLine") == "Examp2.EXE" select el; foreach (XElement el in tests) Console.WriteLine((string)el.Attribute("TestId")); 

This code displays the following result: 0002 0006

Answer 3

Depending on what type of document you want, you can use XmlDocument.LoadXml or XDocument.Load .

Answer 4

Try this code:

 var myXmlDocument = new XmlDocument(); myXmlDocument.LoadXml(theString);
