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>

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
