Re: xalan extensions - get the result tree

[Jan Hoeft]

Hi Mukul,
I found a way to get the processed result as a string and count it:

function count(context, elem){
        transf = context.getTransformer();
        count=transf.transformToString(elem).length();

        transf.executeChildTemplates(elem,true);
        return "";
}

Is it possible to add an attribute to the parent node?
Thanks
Jan

Hi Jan,
   Perhaps you can do this in two passes. In the first pass, you copy the tree:

<text>
   some words
   some more words
</text>

in some variable. Then in second pass, you can find the count of words
and create the required attribute.

Hi,

I am able to do the transformation on my own via executeChildTemplates. But
I have not found a way to process the result.

<xalan:component prefix="my" elements="countwords">
  <xalan:script lang="javascript">
      function countwords(context, elem){
          transf = context.getTransformer();
          transf.executeChildTemplates(elem,true);
          return "";
      }
  </xalan:script>
</xalan:component>

<xsl:template match="/">
  <my:countwords>
      <text>
          some words
          <xsl:value-of select="."/>
      </text>
  </my:countwords>
</xsl:template>

my xml file:

<root>
  some more words
</root>

What i am trying to do is to add an attribute count to the text output.

<text count="5">
   some words
   some more words
</text>

Any idea how to do this?
Cheers
Jan
