Extract DSV text from HTML and XML using XPATH expressions.

Available on Hackage.


If you have an HTML file like this:


    <h1>Some links</h1>
      <li><a href="http://news.ycombinator.com">Hacker News</a></li>
      <li><a href="http://yahoo.com">Yahoo</a>
      <li><a href="http://duckduckgo.com">Duck Duck Go</a>
      <li><a href="http://github.com">GitHub</a>

You can extract a list of tab-separated values like this:

xpathdsv  '//a'  '/a/text()' '/a/@href' < sample.html

GitHub	http://github.com

The first XPATH expression in the command sets the base node on which all the following XPATH expressions are applied. Each of the following XPATH expressions then generate a column of the row of data.

If you don't specify a text() node at the end of an XPATH expression, you'll get a string representation of a node if the node is not an attribute, which may be useful for debugging:

 xpathdsv '//a' '/a' < sample.html
