trouble with variables value not available

[1ded6]

Hello,

Assuming that :

Code: Select all

   <xsl:variable name="eur-uri" select="resolve-uri('prices/eur.xml',base-uri())"/>

   <xsl:variable name="eur-node" select="document($eur-uri)" />

Can someone explain me why this is retrieving some data :

Code: Select all

    <xsl:value-of select="$eur-node//node()[text() = '4.99']/@position" />

and this is not ( i get the message "The variable value is unavailable') :

Code: Select all

    <xsl:variable name="prix-fr" as="xs:string" ><xsl:text>4.99</xsl:text></xsl:variable>

    <xsl:value-of select="$eur-node//node()[text() = $prix-fr]/@position" />

I am working with oxygen 16.1 and saxon 9.5 HE. Any help would be much appreciated. I am really annoyed because when i put my xpath in xwatch, the second option works... :$ tried a lot of things and i can't get it to work with my variable...

Hi,

I created a small XML and XSLT to reproduce your situation.
The XML looks like this:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>

<root>

    <a position="abc">4.99</a>

</root>

and the XSLT looks like this:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

    xmlns:xs="http://www.w3.org/2001/XMLSchema"

    exclude-result-prefixes="xs"

    version="2.0">

    <xsl:template match="/">

        <root>

            <xsl:variable name="eur-uri" select="resolve-uri('eur.xml',base-uri())"/>

            <xsl:variable name="eur-node" select="document($eur-uri)" />

            

            <xsl:variable name="prix-fr" as="xs:string" ><xsl:text>4.99</xsl:text></xsl:variable>

            <xsl:value-of select="$eur-node//node()[text() = $prix-fr]/@position" />

        </root>

    </xsl:template>

</xsl:stylesheet>

On my side the transformation works and produces the proper result, it outputs the "abc" position on the element.
So please give me more details about your problem, maybe some screenshots... Does the publishing fail to produce the desired output or does the XSLT debugger sometimes present the wrong value for certain variables?

Officially we no longer give tech support advice or make fixes for for Oxygen 16:

so maybe at some point you could consider upgrading.

Hello Radu,

Thank you so much for the answer.
I have not thought that the debugger could be wrong and did not check the publishing result.
I'll investigate further in this direction and come back to you.

Regards.

Ok. It was the debugger... lost a day with that.
I will definitely consider upgrading with such a great support ! Thank you !

Hi,

Usually the debugger reports things like The variable value is unavailable because the Saxon 9 XSLT processor may choose to postpone evaluating a variable, for example it may not evaluate the variable at all if it is not used at all or it may evaluate the variable only when it reaches the place where it's used.
