I originally posted this question to the FOP users list,
http://thread.gmane.org/gmane.text.xml.fop.user/29778
I'm writing a stylesheet that includes this template,
<xsl:template match="html:img">
<fo:external-graphic src="url('{...@src}')"/>
</xsl:template>
- but when I process it I get errors like,
$ fop -xml index.html -xsl index.xsl index.pdf

SEVERE: Image not found. URI:
/docs/images/thumb/b/bb/UM-2.1.png/500px-UM-2.1.png. (No context info available)
[...]
- and the generated PDF is missing some images : (
I think the problem is that the stylesheet uses the document() function
to get HTML pages from the web,
<xsl:template match="html:a" mode="foo">
<fo:block>
<xsl:apply-templates select="document(@href)//html:body"/>
</fo:block>
</xsl:template>
- and these pages, e.g. http://ica-atom.org/docs/index.php?title=UM-2.1
- have some relative images,
e.g. /docs/images/thumb/b/bb/UM-2.1.png/500px-UM-2.1.png
The <img> elements are part of the HTML document, and so relative to
http://ica-atom.org/docs/index.php?title=UM-2.1, but I guess the
<external-graphic> elements aren't?
I tried adding an xml:base="" attribute,
<xsl:template match="html:a" mode="foo">
<fo:block xml:base="{...@href}">
<xsl:apply-templates select="document(@href)//html:body"/>
</fo:block>
</xsl:template>
Here's a simplified, complete example,
http://www.sfu.ca/~jdbates/tmp/fop/200911160/index.html
http://www.sfu.ca/~jdbates/tmp/fop/200911160/index.xsl
- but now when I process this example I get this error,
$ fop -xml index.html -xsl index.xsl index.pdf

How can I automatically convert these HTML pages to a PDF with XSL-FO?
