C# XSLT remove node

Question

Could someone help me with this. I need in C# to remove node "xsl:variable" , as you can see here are two xsl:template nodes with child elements xsl:variable . In this sample I need to remove it with C#.

Something like this:

XmlDocument d = new XmlDocument();
d.Load("MyFileName.Xml");
XmlNode t = d.SelectSingleNode("/navigation/page[@id='1']");
t.ParentNode.RemoveChild(t);
d.Save();

But I cant get path of 'xsl:variable' to d.SelectSingleNode()

Please help me ?

THIS IS XSLT:

<xsl:template name="Aggregate:RealECBooleanToXMLBoolean">
        <xsl:param name="RealECBoolean" select="/.."/>
        <xsl:variable name="var1_result">
            <xsl:value-of select="($RealECBoolean = 'Yes')"/>
            <xsl:value-of select="($RealECBoolean = 'YES')"/>
            <xsl:value-of select="($RealECBoolean = 'X')"/>
        </xsl:variable>
        <xsl:variable name="var2_resultof_any" select="boolean(translate(normalize-space($var1_result), 'false0 ', ''))"/>
        <xsl:choose>
            <xsl:when test="string((string((string($var2_resultof_any) != 'false')) != 'false')) != 'false'">
                <xsl:value-of select="(string((string($var2_resultof_any) != 'false')) != 'false')"/>
            </xsl:when>
            <xsl:otherwise>
                <xsl:value-of select="false()"/>
            </xsl:otherwise>
        </xsl:choose>
    </xsl:template>
    <xsl:template name="Aggregate:LookupRECodeName">
        <xsl:param name="RECode" select="/.."/>
        <xsl:call-template name="vmf:vmf1_inputtoresult">
            <xsl:with-param name="input" select="$RECode"/>
        </xsl:call-template>
    </xsl:template>

It may not be finding the node because the 'xsl:' namespace is not defined. This link might help: stackoverflow.com/questions/443250/… — M3NTA7

Thanks M3NTA7 I have a code for getting all xsl:template nodes but next step is to remove all child xsl:variable nodes and I cant do that with this sample upper. Need SingleNode value. — Zire

You need to passs to SelectNodes or SelectSingleNode a name space manager defining the xsl prefix:

XmlNamespaceManager namespaceManager = new XmlNamespaceManager(xDoc.NameTable);
namespaceManager.AddNamespace("xsl" , "http://www.w3.org/1999/XSL/Transform");

and then:

XmlNode variableNode = xDoc.SelectSingleNode("//xsl:variable", namespaceManager);

will select the first xsl:variable element, or

XmlNodeList variableNodes = xDoc.SelectNodes("//xsl:variable", namespaceManager);

will select all xsl:variable elements

Here's an idea. I'm not sure if you will need the 'xsl' name space when using SelectNodes, you will have to experiment with that.

public void YouMethod() {

XmlDocument doc = new XmlDocument();
doc.Load("your.xsl");

XmlNode root = doc.DocumentElement;

// iterate the template nodes
foreach (XmlNode tNode in root.SelectNodes("//xsl:template"))
{
  // iterate the variable child nodes
  foreach (XmlNode vNode in tNode.SelectNodes("xsl:variable"))
  {
      tNode.RemoveChild(vNode);
  } 
}

doc.Save();

}

Thanks again M3NTA7 I see that I have problem with root.SelectNodes("//xsl:template")) part. I was try to remove xsl but there is error again. I figure out that I need XmlNamespaceManager namespaceManager = new XmlNamespaceManager(xDoc.NameTable); 'namespaceManager' and then got this error 'Namespace prefix 'xsl' is not defined.'

Are you still having issues? It would be helpful for us to see the code. That way we can see what you are trying.
