[Interest] xsl:variable & QXmlQuery

[Sébastien Le Ray]

Hi list,

I've a strange behavior with xsl:variables and nested scopes.

First, something like :

<xsl:template match="//whatever"> <whatever>

<xsl:apply-templatesselect="@*"/>

<xsl:for-eachselect="something">

<xsl:variablename="localId"select="@local-id"/>

<xsl:variablename="otherId"select="@other-id"/>

<xsl:iftest="not(boolean(//no/matter/what/*[@attr=$localId]))">

<dont-care/>

</xsl:if>

</xsl:for-each>

</whatever>

</xsl:template>

Does not work under Qt (xsltproc is fine), tracking down the issue it 
appears that $localId is not set when the XPath get evaluated, not a big 
deal, I thought, I simply did something like

<xsl:template match="//whatever"> <whatever>

<xsl:apply-templatesselect="@*"/>

<xsl:for-eachselect="something">

<xsl:variablename="localId"select="@local-id"/>

<xsl:variablename="otherId"select="@other-id"/>

<xsl:iftest="not(boolean(//no/matter/what/*))"> <xsl:if 
test="@attr=$localId">

<dont-care/> </xsl:if>

</xsl:if>

</xsl:for-each>

</whatever>

</xsl:template>

That doesn't work neither.

Only way to make it work I found until now is to somehow output the 
variable before using it eg

<xsl:template match="//whatever"> <whatever>

<xsl:apply-templatesselect="@*"/>

<xsl:for-eachselect="something">

<xsl:variablename="localId"select="@local-id"/>

<xsl:variablename="otherId"select="@other-id"/> <xsl:value-of 
select="$localId"/>

<xsl:iftest="not(boolean(//no/matter/what/*[@attr=$localId]))">

<dont-care/>

</xsl:if>

</xsl:for-each>

</whatever>

</xsl:template>

This works but pollutes the XML

Is this a known limitation or am I missing something?

Is there a way to achieve the same effect without outputing the variable?

Regards
