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>You can do that very easily using only bash.
You only have to add this function:</p>
<pre><code>rdom () { local IFS=\> ; read -d \< E C ;}
</code></pre>
<p>Now you can use rdom like read but for html documents.
When called rdom will assign the element to variable E and the content to var C.</p>
<p>For example, to do what you wanted to do:</p>
<pre><code>while rdom; do
if [[ $E = title ]]; then
echo $C
exit
fi
done < xhtmlfile.xhtml > titleOfXHTMLPage.txt
</code></pre>
</p>
