but still I am not seeing through entirely and it does'nt work as
expected, still.
*[(_at_)lang = $selectedLanguage or (not(@lang) and $defaultLanguage =
$selectedLanguage)]
selects every element which lang attribute is set to the
selectedLanguage or every element which has no lang attribute whenever
the selectedLanguage matches the defaultLanguage. right?
Yes - I wasn't sure how you wanted defaultLanguage to work. I've no idea
whether this logic matches your requirements, it was only a suggestion.
this is why, i get the right result whenever
selectedLanguage=defaultLanguage. When this is not the case I get
nothing. hmm. strange.
so i tried
<xsl:template match="*">
<xsl:choose>
<xsl:when test="(@lang =
$selectedLanguage) or (not(@lang))">
<xsl:apply-imports/>
</xsl:when>
<xsl:otherwise>
<xsl:if test="@lang = $defaultLanguage">
<xsl:apply-imports/>
</xsl:if>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
which is not very beautiful, but still, out of reasons i do not
understand, it seems that the otherwise clause gets executed, even
when the when-clause returns true.
The otherwise clause won't be executed if the when-clause returns true.
There's a bug in your logic here, but if you want help in finding it, you'll
need to provide complete stylesheet and source document, and information on
the parameter values supplied - preferably cut down to illustrate the
problem.
