XPath: Find a node within a text node











up vote

favorite












I have the following html:



<code>The first code block</code>

<p>Some text and <code>the second code block</code> followed by other text</p>


I need to find and remove all code blocks from it. I use the following XPath '//code', but it finds only the first code block while the second remains.



Question: Why '//code' is not able to catch the second code block? How to fix it?



Details: I'm doing it in Ruby using Nokagiry. My code looks like this:



html = Nokogiri::HTML(File.read(htmlFile))

html.search('//code').remove


UPDATE:



The XPath worked in fact. I just made a mistake in different place.
