XPath with variables

[Anonymous]

Hi there,
I have a XML file that looks like this:

 <?xml version="1.0" encoding="UTF-8"?>
<priorities>
<priority-key>
<level>01</level>
<English>High</English>
<German>Hoch</German>
</priority-key>
<priority-key>
<level>02</level>
<English>Normal</English>
<German>Normal</German>
</priority-key>
<priority-key>
<level>03</level>
<English>Low</English>
<German>Niedrig</German>
</priority-key>
</priorities>
 

I have a stylesheet, that looks like that:

<xsl:template match="priorities">
<xsl:param name="curLanguage"/>
<xsl:param name="curPrio"/>
<xsl:value-of[B]select="priority-key[level=$curPrio]/English"[/B]/>
</xsl:template>
 

I would like to change the XPath Expression to point the language that is in curLanguage. I tried
select="priority-key[level=$curPrio]/$curLanguage"
select="priority-key[level=$curPrio]/{$curLanguage}"
select="priority-key[level=$curPrio]/'{$curLanguage}'"

but without success. How does the correct XPath look like?

<xsl:template match="priorities"><xsl aram name="curLanguage"/><xsl aram name="curPrio"/><xsl:value-ofselect="priority-key[level=$curPrio]/English"/></xsl:template>

I think your XPath expr should be like this:

  
<xsl:value-ofselect="priority-key/level[. = $curPrio]/../English"/>

Hi Nimchi,
thx for taking the time to reply. From your reply I see, that I didn't phrase my question clearly. The xpath

<xsl:value-ofselect="priority-key[level=$curPrio]/English"/>

actually does work well. What I want to achieve is to replace English by the content that is in $curLanguage.
This is a very fundamental problem for me: how to construct an xPath expression where the name of a node is a variable. I tried to poke around with the name() function but no luck. The w3school tutorials didn't answer this question too (or I missed it).

maybe you can get all the element under priority-key, and then get the correct element with xsl:if test current() = $whatever, just like this

It's not easy, but I do think it can work

Hi Porky Liu,

thx for your reply. I did a little reevaluating of XLST concepts. You actually can't compare a node to a string. So the solution is to look for something that is a string inside the node. The riddle is solved when you use the name() function. to the answer is:

 <xsl:value-of select="priority-key[level=$curPrio]/*[name()=$curLanguage]"/>
