Question

Seeing the preceding sibling

This is what I'm trying to do:

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

Or

<xsl:if test="parent:Smiley Tonguereceding-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:Smiley Tonguereceding-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... Smiley Wink

    Brandon,

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

    I bow in your presence...
