title: XPath - extract numeric value out of string
body: <pre><code>&lt;Description&gt;this is my value 822880494 this is my value&lt;/Description&gt;
  </code></pre>
  
  <p>I'm quite new to xpath, xml and stylevision so this might be a basic problem.</p>
  
  <p>I am using stylevision 2010 and xpath to create an sps/xslt for an schema.</p>
  
  <p>In the above node you can see there is a numeric value inside the node and I want to extract that value and turn it into a link in my pdf/html. The problem is that i cant seem to extract it. Substring is not an option since the length of the value and the position of the numeric value inside it varies.</p>
  
  <p>Some will probably think that the schema is badly composed and that the numeric value should be in a seperate node/attribute/... There is nothing I can do about that since this schema is provided by another company.</p>
  
  <p>Thanks in advance!</p>
