Re: [xsl] Repeated Recursion on different parts of a tree

> 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>
...
