Hi Sunil, > I have a block of XML where one element my have more then one type > of data as "<type>" element may have either data like profession or > topic or specialty. I want to extract only those node which have a > type profession. > > <cc:keywords> > <cc:keyword> > <type>profession</type> > <ID>1071</ID> > <langstring lang="en_US">Physician</langstring> > </cc:keyword> > <cc:keyword> > <type>specialty</type> > <ID>102</ID> > <langstring lang="en_US">CLINICAL</langstring> > </cc:keyword> > <cc:keyword> > <type>specialty</type> > <ID>115</ID> > <langstring lang="en_US">INFECTIOUS DISEASE</langstring> > </cc:keyword> > </cc:keywords> 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 --- Jeni Tennison http://www.jenitennison.com/ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
