Rendering different templates for the same XML element, at same level

XML: <Root> <Elements> <Element>el1</Element> <Element>el2</Element> </Elements>

XML:

<Root>
  <Elements>
    <Element>el1</Element>
    <Element>el2</Element>
   </Elements>

  <Elements>
    <Element>el1</Element>
    <Element>el2</Element&g开发者_运维知识库t;
   </Elements>
</Root>

Trying to generate to apply two different templates for the same element.

Main template:

<xsl:stylesheet version="1.0">
      <xsl:template match="/Root">
           At root level
             <xsl:apply-templates select="Elements">

             <h1>Render something more</h1>

             <xsl:apply-templates select="Elements" mode="1:Custom">
        </xsl:template>


    <!-- This doesn't render though it is called above-->
      <xsl:template match="Elements"> 
      render something here
      </xsl:template>

    <!-- This renders twice -->
      <xsl:template match="Elements" mode="1:Custom">
      render something else here
      </xsl:template>
</xsl:stylesheet>

If I add mode to the first template, both don't render.

Also tried:

 <xsl:apply-templates select="Elements" mode="1:Custom" />

with the different template to apply as:

<xsl:apply-templates select="Elements" mode="Different" />

Only one of the two(the first one which has the mode specified is rendered). i.e

<xsl:template match="Elements">
</xsl:template>

doesn't render

or <xsl:template match="Elements" mode="Different" />renders twice.

How should I fix this? Everywhere I researched, it suggests to put a priority on the mode. Must be something simple since so many programmers use it?


<?xml version="1.0"?>

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

      <xsl:template match="/Root">
           At root level
             <xsl:apply-templates select="Elements"/>

             <h1>After first template</h1>

             <xsl:apply-templates select="Elements" mode="Custom"/>
        </xsl:template>

      <xsl:template match="Elements">
      <p>First template</p> 
          <xsl:apply-templates select="Element"/>
      </xsl:template>

      <xsl:template match="Elements" mode="Custom">
         <p>Second template      </p>
      </xsl:template>
      </xsl:stylesheet>


<xsl:template match="Elements" mode="1:Custom">

You are using syntactically illegal mode name here (must be a QName) and any compliant XSLT processor must issue an error.

Solution: Just change

    mode="1:Custom"

to

    mode="Custom"

Therefore, this transformation is correct:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output omit-xml-declaration="yes" indent="yes"/>
    <xsl:strip-space elements="*"/>

    <xsl:template match="/Root">
       At root level
     <xsl:apply-templates select="Elements"/>
     <h1>Render something more</h1>

     <xsl:apply-templates select="Elements" mode="Custom"/>
    </xsl:template>

    <xsl:template match="Elements">
       render something here

    </xsl:template>

    <xsl:template match="Elements" mode="Custom">

     render something else here
   </xsl:template>

   <xsl:template match="text()"/>
</xsl:stylesheet>

when applied on the provided XML document:

<Root>
    <Elements>
        <Element>el1</Element>
        <Element>el2</Element>
    </Elements>
    <Elements>
        <Element>el1</Element>
        <Element>el2</Element>
    </Elements>
</Root>

the wanted, correct result is produced:

       At root level

   render something here


   render something here

<h1>Render something more</h1>

 render something else here


 render something else here
