Re: [docbook-apps] Cannot write xml:lang to content.opf

Hi Dave,

You are missing the context.  8^)

When that template is applied, the context is already the top-level book element, so the select statement is trying to select /book/book, which does not exist.

 

Also, you have put @xml:lang in the predicate, but you haven't actually selected its value.  Your current select says "apply templates to a book element that has an @xml:lang", which will process the whole <book> if it has the attribute.  It's a good thing it didn't work.  8^)

 

I would suggest the following:

 

<xsl:value-of select="/*/@xml:lang"/>

 

That will select the value of the top-level element's @xml:lang attribute.

 

If you only want to select if it has such an attribute, then qualify it with a predicate before selecting the attribute:

 

select="/*[@xml:lang]/@xml:lang"

Subject: [docbook-apps] Cannot write xml:lang to content.opf

I have specified an xml:lang value in a book element (i.e. not within an info tag) and need to write that value to the content.opf metadata element.

Here is my customisation:

<xsl:element namespace="http://purl.org/dc/elements/1.1/" name="dcterms:language">
                <xsl:apply-templates
                  select="d:book[@xml:lang]|d:article[@xml:lang]|d:part[@xml:lang]" />
              </xsl:element>

And all I get in content.opf is an empty element:

<dcterms:language xmlns:dcterms="http://purl.org/dc/elements/1.1/" />

What am I missing from the element selection syntax? I'm using 1.76.1, epub2. Thanks
