How to check the node exists in xml and returns the string values by reading CDATA values

I have got below xml in my string and I am using c# 2.0

string strXML ="<?xml version="1.0"?>
<tcm:Error xmlns:tcm="http://www.tridion.com/ContentManager/5.0" ErrorCode="80040329" Category="17" Source="Kernel" Severity="2">
  <tcm:Line ErrorCode="80040329" Cause="false" MessageID="16137">
    <![CDATA[Unable to save Keyword (tcm:0-0-0).]]><tcm:Token>RESID_4574</tcm:Token><tcm:Token>RESID_15309</tcm:Token><tcm:Token>tcm:0-0-0</tcm:Token>
  </tcm:Line>
  <tcm:Line ErrorCode="80040329" Cause="true" MessageID="15200">
    <![CDATA[Name must be unique for items of type: Keyword within this Category and its BluePrint context. Source or sources  of conflict: tcm:236-215788-1024,tcm:237-215788-1024,tcm:241-215788-1024,tcm:243-215788-1024,tcm:423-215788-1024.]]><tcm:Token>RESID_15214</tcm:Token><tcm:Token>RESID_15309</tcm:Token><tcm:Token>RESID_15293</tcm:Token><tcm:Token>tcm:236-215788-1024,tcm:237-215788-1024,tcm:241-215788-1024,tcm:243-215788-1024,tcm:423-215788-1024</tcm:Token>
  </tcm:Line>
  <tcm:Details>
    <tcm:CallStack>
      <tcm:Location>UtilitiesBL.AssertUniqueTitle</tcm:Location>
      <tcm:Location>UtilitiesBL.AssertUniqueTitle</tcm:Location>
      <tcm:Location>KeywordBL.Create</tcm:Location>
      <tcm:Location>XMLState.Save</tcm:Location>
      <tcm:Location>Keyword.Save</tcm:Location>
    </tcm:CallStack>
  </tcm:Details>
</tcm:Error>"

Now I want to write a function which will first check whether string strXML has the xml node node in it, if there is no such node then return "valid" else my function will return the string values taken from above xml.

So my return result will be "Unable to save Keyword (tcm:0-0-0). Name must be unique for items of type: Keyword within this Category and its BluePrint context. Source or sources of conflict: tcm:236-215788-1024,tcm:237-215788-1024,tcm:241-215788-1024,tcm:243-215788-1024,tcm:423-215788-1024.", these text are there in XML.

Please suggest!!

Thanks.

Solution

  • Use:

    XmlDocument xml = new XmlDocument();
xml.LoadXml(strXML);

XmlNamespaceManager xmlnsManager = new XmlNamespaceManager(xml.NameTable);
xmlnsManager.AddNamespace("tcm", "http://www.tridion.com/ContentManager/5.0");

XmlNodeList res = xml.SelectNodes("//tcm:Line/text()", xmlnsManager);


foreach (XmlNode item in res)
{
    Console.WriteLine(item.InnerText);
}
