Hi,
I'm doing some calculation with a Saxon variable, initial value = 0 (internal integer?):

<xsl:variable name="var" saxon:assignable="yes">0</xsl:variable>

I discovered problems when assigning values to a variable:

<saxon:assign name="var">
  <xsl:value-of select="0"/>
</saxon:assign>

Assigning and even XSL-'testing' against expression does not always seem to be working correctly (e.g. value will not be set to 0 and comparison with another value will not result in TRUE/FALSE).

Is there a general issue?

Ciao

This is a product-specific issue so it's best dealt with on the saxon-help list or forum at sourceforge.net. Please supply a complete stylesheet that demonstrates the problem, it's impossible to debug code when you only have fragments.

saxon:assign is a somewhat dubious extension because it breaks the declarative nature of the language, and there can certainly be cases where optimization of the surrounding code causes it not to behave in the way you might expect. The amount of rewrite optimization that Saxon is doing these days is steadily making this problem worse. There's usually a better way of coding the transformation.
