Re: [xsl] xpath help?

["David Carlisle d.p.carlisle@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

 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
