Creating "index" attribute element and incrementing it from 0

[student2]

Hi, I have this input xml :

Code: Select all

<root>
<type>randomtext</type>
<attribute name="ath value"/>
...
<attribute name="nth value"/>
  <attribute name="initial">
    <respondtag>
      <tagtext name="valA">
        <texts>
          <type>ABCDE</type>
          <attribute name="abc" value="def" />
        </texts>
      </tagtext>
      <tagtext name="valB">
        <texts>
          <type>PQRST</type>
          <attribute name="thj" value="trf" />
        </texts>
      </tagtext>
      <tagtext name="valC">
        <texts>
          <type>JKLMN</type>
          <attribute name="lop" value="pth" />
        </texts>
      </tagtext>
      <tagtext name="...">
        <texts>
          <type>...</type>
          <attribute name="type" value="..." />
        </texts>
      </tagtext>
    </respondtag>
  </attribute>
</root>

which I need to transform to this output xml :

Code: Select all

<root>
<type>randomtext</type>
<attribute name="ath value"/>
...
<attribute name="nth value"/>
  <attribute name="initial">
    <respondtag>
      <tagtext name="valA">
        <texts>
          <type>ABCDE</type>
          <attribute name="abc" value="def" />
		  <attribute name="index" value="0" />
        </texts>
      </tagtext>
      <tagtext name="valB">
        <texts>
          <type>PQRST</type>
          <attribute name="thj" value="trf" />
		  <attribute name="index" value="1" />
        </texts>
      </tagtext>
      <tagtext name="valC">
        <texts>
          <type>JKLMN</type>
          <attribute name="lop" value="ptq" />
		  <attribute name="index" value="2" />
        </texts>
      </tagtext>
      <tagtext name="...">
        <texts>
          <type>...</type>
          <attribute name="type" value="..." />
	  <attribute name="index" value="..." />
        </texts>
      </tagtext>
    </respondtag>
  </attribute>
</root>

So I need to add an attribute with name="index" and value="" will increment from 0. This new attribute should be created AFTER the <type>ABCDE</type> for 1st case, <type>PQRST</type> for 2nd case, <type>JKLMN</type> for 3rd case, and similarly for the future <type>...</type> attributes as well.
I need to use XSLT for the transformation. The current XSLT I have is this :

Code: Select all

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>

<xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
</xsl:template>

<xsl:template match="texts">
    <xsl:copy>
        <xsl:copy-of select="*"/>
        <attribute name="index" value="{position()-1}"/>
    </xsl:copy>
</xsl:template>
</xsl:stylesheet>

But I am not getting the desired output from this XSLT. Could someone kindly help me out with this?

Hi,

Using the "position()" function makes sense when you are inside a xsl:for-each element, otherwise it will probably always return "1".
Maybe you can use the "preceding:::" xpath axis, something like count(preceding::texts)

preceding Selects all nodes that appear before the current node in the document, except ancestors, attribute nodes and namespace nodes

I do not want to help too much because it's probably your homework, right?
