Subject: Re: [xsl] xsl:key problem (probably!) From: Joerg Heinicke <joerg.heinicke@xxxxxx> Date: Thu, 07 Feb 2002 13:11:16 +0100 |
Hi,
I got the following code:
... <xsl:key name = "accountvalue" match ="/STATEMENT_OF_CHANGE/ACCOUNT_VALUES/ACCOUNT_VALUE" use = "ACCOUNT_NUMBER" /> ...
and then I call the key() function like this:
...
<xsl:variable name="accnr" select="@account_number" />
<xsl:variable name="accv" select="key('accountvalue', $accnr)" />
<!--<xsl:value-of <xsl:value-of select="$accv/VALUE[@currency='LW']" />
...
This works perfectly fine, when the "/STATEMENT_OF_CHANGE/ACCOUNT_VALUES/ACCOUNT_VALUE" node exists. If it doesn't XALAN 2.0 throws a NullPointerException (in the value-of statement!)
I tried to test the existence of then node, using things like:
<xsl:if test="$accv"> or <xsl:if test="$accv/VALUE">. (Here you also get some type of exception...)
Is this noraml, a bug or is it just me not knowing what do to?
Thanks in advance!
