Subject: Re: [xsl] Stumped on why a field isn't showing up From: "J.Pietschmann" <j3322ptm@xxxxxxxx> Date: Sun, 13 Jun 2004 13:50:00 +0200 |
I'm trying to learn XSL(-FO), so I'm still beating my head against the wall.
I've managed to get everything except, oh, the most important piece of information to render correctly.
It seems you are missing some important concepts, in particular the concept of the context node in an XSLT template:
...<xsl:template match="/"> <fo:root font-family="Courier" font-size="12pt">
<xsl:apply-templates select="novel/chapter"/>
At this point the context node is the tree's root node. You are telling the processor to get the node set containing the novel/chapter nodes and apply templates, which will hopefully be matched by the following template:
<xsl:template match="chapter"> <fo:page-sequence master-reference="manuscript-body"> <fo:static-content flow-name="xsl-region-before"> <fo:block text-align="right" space-before="1in" end-indent="1.5in"> <xsl:value-of select="/novel/heading"/> / <fo:page-number/>
Here you use an absolute XPath, which will get you the string value of /novel/heading, something you probably expect.
<fo:flow flow-name="xsl-region-body" line-height="1.5"> <xsl:apply-templates select="novel/author"/>
However, at this point you use a relative XPath (no slash "/" in format). This means the processor will try to walk it down from the context node, which is most likely a /novel/chapter node. I suppose these nodes don't have a novel child, and you wont get to the /novel/author node anyway. You want to use <xsl:apply-templates select="/novel/author"/> <xsl:apply-templates select="/novel/address"/> here.
You should probably think about restructuring your processing logic. In many cases it's considered "bad style" to grab parts outside the subtree starting at the currently processed node. A way to avoid this is to use template parameters, they have their own set of drawbacks though.
