[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Creating Headers in XSL:FO that correspond to chapter
I have recently been converting an installation guide written in xml to a
pdf document using the xsl:fo translating language. I am fairly new
to both xsl and fo, so please excuse the possible naivety of my questions.
I am writing to ask for advice on placing chapter numbers on page headings
corresponding to pages within those chapters.
The XML document that I'm using has been summarized below:
<book>
<title>
text
</title>
<chapter>
<title>titleval1</title>
<body>text</body>
</chapter>
<chapter>
<title>titleval2</title>
<body>....</body>
</chapter>
<chapter>
<title>titleval3</title>
<body>....</body>
</chapter>
</book>
In my xsl, I'd like to have a header that displays both the title
of the book, and the chapter number. Here is a clip of code
from my xsl that displays the header:
<fo:static-content flow-name="xsl-before">
<fo:block text-align-last="centered" font-size="10pt">
<xsl:value-of select="title" />
<xsl:text>/Chapter </xsl:text>
<!-- Commands for Chapter Number go here -->
</fo:block>
<fo:display-rule />
</fo:static-content>
I number my chapters using the <xsl:number /> function. I'll give
you a better idea of how I do this by displaying a piece of my
<xsl:template match="chapter"> template, which shows the code behind
chapter cover pages:
<xsl:if test="@pagebreak='yes'">
<fo:block break-before="page" font-size="30pt"
space-before.optimum="125pt" text-align-last="centered"
line-height="40pt" font-weight="bold">
<xsl:text>Chapter </xsl:text>
<xsl:number />
</fo:block>
</xsl:if>
<xsl:if test="not(@pagebreak='yes')">
<fo:block font-size="30pt" space-before.optimum="125pt"
text-align-last="centered" line-height="40pt" font-weight="bold">
<xsl:text>Chapter </xsl:text>
<xsl:number/>
</fo:block>
</xsl:if>
I'm finding it difficult to display the current chapter number in the
header since there doesn't seem to be a way for me to conditionalize
the header based on page number. If there is a page-number-position
function, I can tell the header to display different chapter numbers
depending on the page its on.
A more robust way (in terms of code) of displaying chapter numbers would
involve finding a way to communicate to the header the chapter that is
currently being displayed in the region-body. Although this seems
rather simple, variations of the <xsl:for-each> and <xsl:value-of select>
functions have left me with few results. I have only found ways to
display one chapter number throughout the entire installguide, or
all three chapter numbers together (123) throughout the guide.
I greatly appreciate any help you can give me. Thank you in advance.
