Hi Jay,

Is the order of declaration what's important in the document, or does
the parser detect dependencies so that this would work...?

<xsl:stylesheet>

                <xsl:variable name="C">
                                 some processing dependent on A,B,etc.
                 </xsl:variable>

                 <xsl:variable name="B">
                                 some processing dependent on B
                 </xsl:variable>

                 <xsl:variable name="A">
                                 some processing...
                 </xsl:variable>

                 <xsl:template match="/">
                                 transform
                 </xsl:template>
</xsl:stylesheet>

I assume that the former is the case, but you never know.

Thanks,

Matt

Hi, Matt,

For the most part, yes. However, beware of circular definitions (which
no
language can handle).

<xsl: variable name="a">
  some processing dependent on the value of $b
</xsl:variable>

<xsl: variable name="b">
  some processing dependent on the value of $a
</xsl:variable>

will break.

And while it looks simple in this very obvious case, it can be hell to
figure out in practice, when it's halfway through 3,000 lines of souce
code in multiple files. So I try to keep those kinds of things together
in
the same file and write comments so that I can figure out what I did
when
I come back to that stretch of code next year.

Spam:[xsl] Xsl:variable question






Hello,

If I declare more than one global variable in a document, can I be
ensured that the global variables will be instantiated in a particular
order?

For instance, if I do this,

<xsl:stylesheet>

                 <xsl:variable name="A">
                                 some processing...
                 </xsl:variable>

                 <xsl:variable name="B">
                                 some processing dependent on B
                 </xsl:variable>

                 <xsl:variable name="C">
                                 some processing dependent on A,B,etc.
                 </xsl:variable>

                 <xsl:template match="/">
                                 transform
                 </xsl:template>
</xsl:stylesheet>

Will I be ensured that C will be processed after B and after A,etc?

Thanks,

Matt
