title: XSL: chop off string at arbitrary place
body: <p>I'm using XSL to get an XML styled. The xsl defines a table with two columns. Thanks to Kevin Brown, the following code works fine to chop off at a word boundary, but what I need is to chop off at an arbitrary place.</p>
  
  <pre><code>&lt;fo:table-cell&gt;
      &lt;fo:block-container overflow="hidden" height="15pt"&gt;&lt;fo:block&gt;this is a very, very, very long text here&lt;/fo:block&gt;&lt;/fo:block-container&gt;
  &lt;/fo:table-cell&gt;
  </code></pre>
