Hi Folks,
Would you please recommend an XPath expression which ensures that the content
of<author> is optional whitespace,<Person>, optional whitespace, and nothing
else:
<author>
<Person>
<name>Simon L. Peyton Jones</name>
</Person>
</author>
The result of the XPath expression is true if the content is as desired and
false otherwise. The XPath should return true for the above example and false
for the below example:
<author>
The person is:
<Person>
<name>Simon L. Peyton Jones</name>
</Person>
</author>

most of your replies have used normalize-space for testing ws text
nodes, but if you are using xpath from xslt (or other contexts where you
can control the parse) an alternative is to throw away white space text
children of author at XDM build time, which simplifies the expression
greatly.
so
<xsl:strip-space elements="person"/>
then then can go
Person and not(node()[2])
