Counter in XSLT

[blacksab]

Hi All,

I'm having trouble counting the number of occurring nodes from my input XML.

I have this input:

<root>
  <level1>
    <countMeIn1/>
  <level1>
  <level1>
    <countMeIn2/>
  <level1>
  <level1>
    <countMeIn3/>
    <countMeIn4/>
    <countMeIn5/>
  <level1>
</root>
 

And my desired output is:

<root>
  <countMeIn count="1"/>
  <countMeIn count="2"/>
  <countMeIn count="3"/>
  <countMeIn count="4"/>
  <countMeIn count="5"/>
</root>
 

I have tried the position() function but that only renders an incremented number for 3,4 and 5.

Any help would be greatly appreciated.

@blacksab
could you explain, how you want to count the nodes, because I can’t follow your calculation.

Hi Dormilich,

I explained my input badly. In my input XML I have several nodes named countMeIn. I want to do a sequential count of the included countMeIn nodes in the output XML

 <root>
   <level1>
     <countMeIn/> <!-- Want an attribute named count="1" for this node-->
   <level1>
   <level1>
     <countMeIn/> <!-- Want an attribute named count="2" for this node-->
   <level1>
   <level1>
     <countMeIn/> <!-- Want an attribute named count="3" for this node-->
     <countMeIn/> <!-- Want an attribute named count="4" for this node-->
     <countMeIn/> <!-- Want an attribute named count="5" for this node-->
   <level1>
 </root>

after some thinking I came up with 2 ideas
1. use the DOM
2. use XSLT twice, the first one is only for grabbing the <CountMeIn> nodes, the second one you can use to make the count attribute.

This is solved:

This node to do the assignment to counter:
<xsl:variable name="counter">
<xsl:number level="any" count="countMeIn"/>
</xsl:variable>

And then this node to output the value as an attribute:
<xsl:attribute name="line">
<xsl:value-of select="$counter"/>
</xsl:attribute>

This solution was also given on another thread in this forum.

Thank you for your input.
