add element unique Id XSLT

[mvujica]

I am quite new to XSLT and I want to add unique index to elements types to transform something like this:

<item1>
<item2>
<item3></item3>
<item3></item3>
</item2>
<item2>
<item3></item3>
<item3></item3>
</item2>
</item1>
<item1>
</item1>

into:

<item1 id="1">
<item2 id="1">
<item3 id="1"></item3>
<item3 id="2"></item3>
</item2>
<item2 id="2">
<item3 id="3"></item3>
<item3 id="4"></item3>
</item2>
</item1>
<item1 id="2">
</item1>

I tried using position() but it counts based on context and not globally on document. Thanx. :^)

I have got the answer from daniweb (thanks fpmurphy) :

1.  <?xml version="1.0"?>
   

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

3.  <xsl:output method="xml" indent="yes"/>
   

5.  <xsl:template match="/">
   

6.  <xsl:apply-templates/>
   

7.  </xsl:template>
   

9.  <xsl:template match="\*">
   

10.  <xsl:variable name="name" select="name()" />
    

11.  <xsl:element name="{name()}">
    

12.  <xsl:attribute name="id">
    

13.  <xsl:value-of select="count(preceding::\*\[name()=$name\]) + 1" />
    

14.  </xsl:attribute>
    

15.  <xsl:apply-templates />
    

16.  </xsl:element>
    

17.  </xsl:template>
    

19.  </xsl:stylesheet>
