Re: [xsl] linux xslt debugger/ profiler | AW: AW: AW: AW: AW: AW: [xsl] xhtml output formating problems / passing through pre defined static xhtml
Sorry, the source xml in the example should read:

<root> 
  <a> 
    <xml> 
      <Schema> 
        <ElementType> 
          <attributeType> attA-1</attributeType>
        </ElementType> 
      </Schema> 
    </xml> 
  </a> 
  <b> 
    <xml> 
      <Schema> 
        <ElementType> 
          <attributeType> attB-1</attributeType>
        </ElementType> 
      </Schema> 
    </xml> 
  </b> 
  <c> 
    <xml> 
      <Schema> 
        <ElementType> 
          <attributeType> attC-1</attributeType>
        </ElementType> 
      </Schema> 
    </xml> 
  </c> 
  <b> 
    <xml> 
      <Schema> 
        <ElementType> 
          <attributeType> attB-2</attributeType>
        </ElementType> 
      </Schema> 
    </xml> 
  </b> 
  <a> 
    <xml> 
      <Schema> 
        <ElementType> 
          <attributeType> attA-2</attributeType>
        </ElementType> 
      </Schema> 
    </xml> 
  </a> 
</root>
