Seeing the preceding sibling

[ptc-3050150]

This is what I'm trying to do:

<xsl:if test="name(parent:receding-sibling)='volume">

Or

<xsl:if test="parent:receding-sibling::volume">

Some of these XPath chapters show 3 in a row, but the parser just goes Pffft.

Test if the parent's preceding sibling is <volume>.

The parent tag varies, but will either have <volume> right above it or it won't.

I've written it a hundred ways wrong and now my eyes are blurred from banging my head on my desk.

Can't even run a good test to find it.

<xsl:value-of select="name(parent:receding-sibling)"/">

Adding ::node() just throws a parser error.

Thanks...hope it is just another can't see the forest for the trees...what am I missing?

John,

There can only be one axis specifier ("parent::",
"preceding-sibling::", etc.) per step and it must be followed by a
node test.  So, your case would be something like:

<xsl:if test="parent::*/preceding-sibling::volume">...</xsl:if>

or just:

<xsl:if test="../preceding-sibling::volume">...</xsl:if>

Note that this would be true if *any* of the parent's preceding
siblings are a "volume" element.  To check if just the immediately
preceding sibling is a volume:

<xsl:if test="../preceding-sibling::*[1][self::volume]">...</xsl:if>

Hope your head gets better...

Brandon,

Thanks for the lecture! Finished it up today and my head feels much better now.

I bow in your presence...
