This piece of XML is well-formed, but it doesn't conform to the
namespaces Recommendation because it doesn't have a namespace
declaration for the 'cc' prefix, so an XSLT processor won't be able to
use it. Assuming it actually looks like:

<cc:keywords xmlns:cc="http://www.cecity.com/xml/cecity_classification">
...
</cc:keywords>

I'm also going to assume that you don't have a default namespace
declaration in your source XML document. If you do, then the answer is
different.

You need to declare the
http://www.cecity.com/xml/cecity_classification namespace in your
stylesheet:

<xsl:stylesheet version="1.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:cc="http://www.cecity.com/xml/cecity_classification">
...
</xsl:stylesheet>

then you need to start from the root node:

  /

travel down step by step to the cc:keyword elements:

 /cc:keywords/cc:keyword

and use a predicate to identify those whose child type element (in no
namespace) is equal to the string 'profession':

  /cc:keywords/cc:keyword[type = 'profession']

I hope that helps,

Jeni
