title: How to use regular expression in lxml xpath?
body: <p>I'm using construction like this:</p>
  
  <pre><code>doc = parse(url).getroot()
  links = doc.xpath("//a[text()='some text']")
  </code></pre>
  
  <p>But I need to select all links which have text beginning with "some text", so I'm wondering is there any way to use regexp here? Didn't find anything in lxml documentation</p>
