Re: [docbook-apps] Match on Language

[Bob Stayton <bobs@sagehill.net>]

Hi Peter,
The complication here is the "all elements" requirement.  Each element 
has its own template for general formatting before it gets down to the 
text where you could set a font.  For example, a section element could 
have a lang attribute. All of the nested elements inside a section have 
their own templates.  I doubt you would want to customize a whole raft 
of elements to achieve this.

Fortunately, you don't have to.  Since you are only changing the font, 
you can operate at the text level.  Try this:

<xsl:template match="d:*[@lang = 'el']//text() | d:*[@xml:lang = 
'el']//text()">

  <fo:inline font-family="FontName">
    <xsl:copy/>
  </fo:inline>

</xsl:template>

The match attribute on the template finds elements with the lang 
attribute, and then selects any descendant (using double slash) text() 
nodes, regardless of what the sequence of descendants is.

For the text node, it generates an fo:inline and sets the font-family.

This approach works if you are not adding other custom templates that 
match on text() nodes.  Since the processor won't apply more than one 
matched template, this would have to coordinate with them.

I didn't test this, so let me know if it doesn't work.
