Hi Roland,
nothing seems to be wrong. Try to use the release version Xalan 2.2. I
never had such a bug.

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!
Roland
