Re: [xsl] A - B

[pcoustillas <pcoustillas at perinfo dot com>]

 thanks, but if i have this XML :
<A>37</A>
<B/>

and my XSL :
<xsl:decimal-format NaN="0" name="forme1" decimal-separator="," 
grouping-separator=" " />

the result is 0 but i expect 37. i've been suggested to use 
<xsl:value-of select="format-number(concat('0',11) - concat('0',1), '# 
##0,00','forme1')" />

or

<xsl:value-of select="format-number(number(concat('0',11)) - 
number(concat('0',1)), '#  ##0,00','forme1')" />
but it is a bit complicated... isn't there something more simple...

To Marrow : i faced troubles while using sum with the tag <B/> i revieve 
"NaN"

other suggestions ??

Thank.
