Re: [xsl] xpath help?

Hey Dan,

Actually, you have (used the axes). Often people use XPath without knowing
that's what they are doing.

Every time you say 'div/h1' you are saying 'child::div/child::h1'.

'span/@class' is short for 'child::span/attribute::class'. Etc.

Search for "XPath abbreviations" - for example, I get this page back:

https://www.stylusstudio.com/docs/v2007/d_xpath95.html

There is also the XPath 1.0 Recommendation:

https://www.w3.org/TR/1999/REC-xpath-19991116/#path-abbrev

Cheers, Wendell

Thanks, I don't think I've ever seen an XPath example with parents before.
I've certainly never used them. This did fix the problem.

..thanks

Subject: Re: [xsl] xpath help?

 you are selecting all elements that are the first child of their parent

use

(//a[contains(@filepath, 'preface.html')])[1]/@newid

or

/descendant::a[contains(@filepath, 'preface.html')][1]/@newid

I have this xpath that returns more than one result

//a[contains(@filepath, 'preface.html')]/@newid

I thought adding [1] to it like this would get me the first entry, but
the result doesn't change

//a[contains(@filepath, 'preface.html')][1]/@newid

Here is an example of the file I'm processing
