Ok thanks James.
I am aware of the call-template tag.
However the issue I have was with the fact that
if I was to call the template by name, how would I deal
with the fact that I want to use the first <bitfield> node,
and then the next and then the next etc.. with each pass of
recursion?
Below it is done by the select attribute, which
<call-template> does not have?
Thanks for the book reference. I have just ordered
Michael Kays XSLT Programmers reference, but I may add that
to my shopping list to.
Thanks

try <xsl:call-template/> tag.

Subject: Re: [xsl] Repeated Recursion on different parts of a tree
Hello,
Is there anyway I can perform the below operation by
'calling' a template by name, instead of using a template
match?
<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>
...
My XML looks like:
<register name="DATA" offset="0">
<no_of_regs>1</no_of_regs>
<descriptivename>Data register</descriptivename>
<description>The ...ster.</description>
<description>In ord..H.</description>
<description>..Oe...</description>
<bitfield name="DATA">
<function>Input data.</function>
<bitpos>0</bitpos>
<no_of_bits>10</no_of_bits>
<initialvalue>0</initialvalue>
<accesstype>R</accesstype>
</bitfield>
<bitfield name="CONTROL">
<function>Output data</function>
<bitpos>10</bitpos>
<no_of_bits>6</no_of_bits>
<initialvalue>0</initialvalue>
<accesstype>RW</accesstype>
</bitfield>
etc..........
</register>
<register name="SWAP" offset="10">
<no_of_regs..........
(I want to use values in each bitfield to create an
expression for the whole <register> e.g output document to
look like - Register DATA initialValue = X......)
My existing XSL stylesheet already has a few templates
which are called 'by name'. So when I implement the above,
I an getting junk in my output document. (actually I seem
to get the source xml element value output for each first
<bitfield> element)
Therefore I would like to call the template by name so as
not to incur these side effects. Any ideas?
Thankyou
PD

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>
...
