Nested apply-templates calls run out of stack space -

Subject: Nested apply-templates calls run out of stack space - alternative xslt

out of stack space
XSLT 1.0

The XSLT below fails as there are too many lines
between the start and the stop (6000 lines in one of
my input docs)....
[error]
Nested apply-templates calls run out of stack space. 

I have tried work arounds to no avial.... if anyone
has any insite into creating a new stylesheet that
does not run out of stack space I would be
appreciative....

Mr Kay suggested the following but this is beyond my
personal XSLT knowledge

Define a key for each of the elements that's the
generate-id() of the 
most
recent preceding sibling that matches "Point A" or
"Point B". Then do
Muenchian grouping using this key. 

the basic premise is that between point SSDD_START and
point SSDD_STOP need to extract information that has
R[xxx] in the data....

SSDD_START and SSDD_STOP can occur once of many times
in the document

xml out - I understand this is not what the xslt is
doing but if you can get to this stage I can work out
the rest.

<root>
	<text>R[3]</text>
	<text>R[4]</text>
	<text>R[6]</text>
</root>
