Hello,

I have an xmlnode containing data about the financial results of a company, like this:

<company>
........
<financial>
<income>345000</income>
<expense>256100</expense>
</financial>
</company>

I wrote an xslt template, to get the result:

<xsl:template name="mycalc">
<xsl:param name="a"/>
<xsl:param name="b"/>
<xsl:value-of select="$a-$b" />
</xsl:template>

template call:

<xsl:call-template name="mycalc">
<xsl:with-param name="a" select="income" />
<xsl:with-param name="b" select="expense" />
</xsl:call-template>

I got an error:

Unexpected 'eof'token: '$'. $a--->$<--b.
Can anyone tell me the right way to use the "-" operator? "/" also returns an error, "+" and "*" were OK.

Thanks in advance!

XML allows hyphens in names, so the minus operator must be separated from a preceding name by a space.

Comes naturally to COBOL old-timers...

thanx,

it works with space around the hyphen.
just for curiosity, how can you solve with the "/" divide character?
Space is not a good point any more, in that case. It triggers an error:

Nodetest required $a / -->$<--b. !!!

Here is s great site to help you out...

thanx,

full description of all I wish.

The divide operator in XPath is not "/", it is "div". "/" is a path operator. And of course, "div" must be separated from its operands by spaces (there's been some debate about whether "1div2" is legal in XPath 1.0, I forget the outcome, but adding spaces certainly does no harm!)
