> cant dynamically update a variable in XSL while traversing the tree.
you just need to make your variable a parameter to your template and
pass on the parameter at the same time as traversing the tree.
You;ll probably want to traverse th etree one at a time rather than
applying templates to a set of sibling nodes at the same time as that
helps keep ones notion of paremeter passing and template invocation in
sync.
that is, instead of doing
<xsl:template match="register">
... <xsl:apply-templates select="bitfield"/>....
do
<xsl:template match="register">
... <xsl:apply-templates select="bitfield[1]"/>....
with
<xsl:template match="bitfield">
<xsl:param ... whatever parameters you need .../>
... some sums ...
<xsl:apply-templates select="following-sibling::bitfield[1]">
<xsl:with-param ... new values passed to the next
</xsl:apply-templates>
...
