How to parse XML in Bash?
Ideally, what I would like to be able to do is:
cat xhtmlfile.xhtml |
getElementViaXPath --path=\'/html/head/title\' |
sed -e \'s%(^|</title&>

<p>Another command line tool is my new Xidel. It also supports XPath 2 and XQuery, contrary to the already mentioned xpath/xmlstarlet. </p>
<p>The title can be read like:</p>
<pre><code>xidel xhtmlfile.xhtml -e /html/head/title > titleOfXHTMLPage.txt
</code></pre>
<p>And it also has a cool feature to export multiple variables to bash. For example</p>
<pre><code>eval $(xidel xhtmlfile.xhtml -e 'title := //title, imgcount := count(//img)' --output-format bash )
</code></pre>
<p>sets <code>$title</code> to the title and <code>$imgcount</code> to the number of images in the file, which should be as flexible as parsing it directly in bash.</p>
