Thank you Jeni for explaining this so clearly.
(Is this the right place to say that I found your
webpages on XSL very helpful indeed? :)
Regards,
Sean

Subject: Re: [xsl] Inheriting an attribute from first ancestor that defines
it
Hi Sean,
Specifically, is there a more general way (than specifying
test="../@attr", test="../../@attr") to select the first ancestor
travelling back up the tree that defines a specific attribute?
Sure: select all the ancestor elements:
ancestor::*
filter them to select only those with style attributes:
ancestor::*[(_at_)style]
and then pick the first of those that you find:
ancestor::*[(_at_)style][1]
(You can use [1] to select the nearest to the element you're on -- the
last in document order -- because the ancestor axis is a "reverse"
axis.)
In your stylesheet, you could just do:
<xsl:template match="page">
<page>
<xsl:copy-of select="@* | ancestor::*[(_at_)style][1]/@style"/>
<xsl:apply-templates/>
</page>
</xsl:template>
Cheers,
Jeni
