    copied!<p>At work I've been given the fun task of generating PDFs with XSL. The XML structure I'm working with is similar to</p> <pre><code>&lt;records&gt; &lt;topLevel&gt; &lt;topLevelID&gt;&lt;/topLevelID&gt; &lt;secondLevel&gt; &lt;secondLevelID&gt;&lt;/secondLevelID&gt; &lt;thirdLevel&gt; &lt;/thirdLevel&gt; &lt;thirdLevel&gt; &lt;/thirdLevel&gt; &lt;/secondLevel&gt; &lt;/topLevel&gt; &lt;topLevel&gt; &lt;topLevelID&gt;&lt;/topLevelID&gt; &lt;secondLevel&gt; &lt;secondLevelID&gt;&lt;/secondLevelID&gt; &lt;thirdLevel&gt; &lt;/thirdLevel&gt; &lt;thirdLevel&gt; &lt;/thirdLevel&gt; &lt;/secondLevel&gt; &lt;/topLevel&gt; &lt;/records&gt; </code></pre> <p>I would try to give a more meaningful example of the XML, but I don't feel like approaching any legal boundaries that may exist. With that XML structure, I have to output a block of text in the PDF for every <code>thirdLevel</code> node. The XSL I have so far is like</p> <pre><code>&lt;xsl:for-each select ="topLevel"&gt; &lt;xsl:variable name="topID" select="topLevelID"/&gt; &lt;xsl:for-each select ="secondLevel"&gt; &lt;xsl:variable name="secondID" select="secondLevelID"/&gt; &lt;xsl:for-each select="thirdLevel"&gt; &lt;fo:block-container position="absolute" height="12.8pt" width="220.8pt" left="160pt" display-align="auto"&gt; &lt;xsl:attribute name="top"&gt; &lt;xsl:value-of select="concat(193 + [whatshouldgohere]), 'pt')"/&gt; &lt;/xsl:attribute&gt; &lt;fo:block font-size="7pt"&gt; &lt;xsl:call-template name="insertThirdLevel"/&gt; &lt;/fo:block&gt; &lt;/fo:block-container&gt; &lt;/xsl:for-each&gt; &lt;/xsl:for-each&gt; &lt;/xsl:for-each&gt; </code></pre> <p>Basically, I need to add some value to the top attribute to make the text for each <code>thirdLevel</code> node appear on its own line. I've tried using combinations of adding/multiplying by the ID (starts at 1 and increases by 1 for each set) and <code>position()</code>, but I can't seem to get it right.</p>

An individual column

Larger individual text columns get their own page to allow for proper reading.
