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" Bob Stayton Sagehill Enterprises [email protected] ----- Original Message ----- From: Xmplar To: [email protected] Sent: Thursday, December 01, 2011 11:38 PM 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 -- Dave Gardiner
