XPath Help and Pagebreak

emellaich · 07-27-2009, 09:59 PM

Hello all,

I'm just looking for some clarification on XPath. I've been playing around and its not doing what I expected, so I thought I would ask a quick question here. In the Calibre help it gives the following:

//h2[re:test(., 'chapter|section', 'i')]
(Selects <h2> tags that contain the words chapter or section)

What exactly is meant by contains? Does 1) or 2) below contain 'chapter'?

1) <h2 attribute=chapter>Headline</h2>

2) <h2>Chapter</h2>

Also, what do I do to force a pagebreak before a chapter break. I am converting from epub (html) to mobi. I've checked the appropriate meta data box, but it doesn't seem to be working. Maybe its my XPath problem. Or is there some other trick?

I insert page breaks by hand. Here is what I use:

<div style="page-break-before:always" />

2) and the calibre viewer doesn't support page breaks in MOBI, so check it with another viewer
