Subject: Re: [docbook-apps] Color In Syntax Highlighting

There is a "highlight.xsl" specific for the XSL-FO PDF publishing which
matches various syntax highlight range elements and adds bold or italic
styling to them like:

> <xsl:template match='xslthl:value' mode="xslthl">
> <fo:inline font-weight="bold"><xsl:apply-templates mode="xslthl"/></fo:inline>
> </xsl:template>

For example we have replaced the default PDF styling templates for our
Oxygen XML user's manual with templates applying color styling:

> 
> <xsl:template match='xslthl:keyword' mode="xslthl">
> <fo:inline font-weight="bold" color="#7f0055"><xsl:apply-templates mode="xslthl"/></fo:inline>
> </xsl:template>
>
> <xsl:template match='xslthl:string' mode="xslthl">
> <fo:inline font-weight="bold" font-style="italic" color="#2a00ff"><xsl:apply-templates mode="xslthl"/></fo:inline>
> </xsl:template>
>
> <xsl:template match='xslthl:comment' mode="xslthl">
> <fo:inline font-style="italic" color="#006400"><xsl:apply-templates mode="xslthl"/></fo:inline>
> </xsl:template>
>
> <xsl:template match='xslthl:tag' mode="xslthl">
> <fo:inline font-weight="bold" color="#000096"><xsl:apply-templates mode="xslthl"/></fo:inline>

> <xsl:template match='xslthl:xslt' mode="xslthl">
