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
