Child Nodes Selection

[Bryan Galvin]

Hi all,

Is it possible to 'cherry-pick' child nodes but retain their
parentage. Given an example...

<user>
<first_name>George</first_name>
<sur_name>George</sur_name>
<dob>George</dob>
<title>Line Manager</title>
</user>

I would like to obtain a node-set that gives me...
<user>
<first_name>George</first_name>
<sur_name>George</sur_name>
</user>

I am trying to achieve this is a single XPATH expression, creating a
variable to hold my new smaller node-set. I am trying to make my
stylesheets less memory intensive by only focusing on those elements I
am interested. Effectively working with smaller records.

Any assistance is very appreciated,

Bryan Galvin

No.

XPath is a way of identifying (by "paths") nodes in a document. It
can never return a node that is not in the input. You need to create
a new element with the children you want, or modify an existing node,
and XPath cannot do either of these things.

Richard,

As I suspected. From all my experience of XPATH and XSLT I could not
see how it was feasable. I have embarked on an alternative path where
the nodes I require are prepared several stages before hand into a
<compound_key> element.
