select nodes where a grandchild's text is not some value?

[SkipSailors]

I have some XML that I want to transform to some XML:

<element>
    <child>
        <grandchild>
            otherWord
        </grandchild>
        <grandchild>
            triggerExclusion
        </grandchild>
    </child>
</element>
<element>
    <child>
        <grandchild>
            otherWord
        </grandchild>
    </child>
</element>
 

I want to copy elements where 'triggerExclusion' is not the text of its grandchild subelement. In this example I want to copy the second element, not the first.

This doesn't work for me:

<template match="element[not(child/grandchild eq 'triggerExclusion')"]>
    <copy>
        <apply-templates/>
    </copy>
</template>
 

My Saxon warns that a sequence can't be the first argument of the eq operator, and, I guess, only looks at the first grandchild.

Please, how do I select elements where a descendent of arbitrary depth has some value?

TIA

Hi,

What you could do is select every child-element that doesn't contain a grandchild with the text "triggerExclusion".

It could look something like this:
(don't quite remember the syntax, but isn't text() a function that returns the value of an element?? In this case it could be "triggerExclusion"...anyway)

[HTML]//child/grandchild/text() != "triggerExclusion"[/HTML]

That should at least get you started if you haven't solved it already.

thank you for the thought. This would select grandchild elements that don't have the trigger. What I want is to select elements such that the grandchild doesn't have the trigger.

Something like --

//element[some test on grandchild I can't figure]

element[child/grandchild/text() != 'triggerExclusion']

note: about the same as in your post...

Wouldn't this select the first element since it has a child/grandchild node that isn't equal to triggerExclusion?

I would suggest just replacing the eq with a =.

<xsl:template match="element[not (child/grandchild = 'triggerExclusion')]">
<xsl:copy-of select="."/>
</xsl:template>
<xsl:template match="element"/>

I don't think so. It will select all <element> elements, that have not even one <grandchild> element with "triggerException". In this case, it should select the second one. note that the expression child/grandchild/text() is actually a node-set*, since there are two <grandchild> elements.

Or to ask it the other way round: what's the difference between element[child/grandchild/text() != 'triggerExclusion']** and element[not(child/grandchild/text() = 'triggerExclusion')] ? to me it is the same.

in this case (string) grandchild/text() and (string) grandchild gives the same, because there are no further child elements with text nodes (see specs @ w3c)

* you can test it with count(child/grandchild/text()), though I'm quite positive that the result will be 2
** expanded XPath is child::element[child::child/child::grandchild/child::text()]
