I think that rather than using xsl:analyze-string to analyze the value of
regex-group(5), I would use a sequence of calls on matches():
<xsl:variable name="fname" select="regex-group(5)"/>
<xsl:choose>
<xsl:when test="matches($fname, 'b$')">...
<xsl:when test="matches($fname, 'm$')">...
<xsl:otherwise>...

Subject: [xsl] xsl:analyze-string
Problem:
I have xml looking like
<record>19/08/1992 09:08 111938 500014.08b</record>
Of interest is the last field, the dos file name.
Its general form is
nnnnnn.nnA n=int, A =A-Z.
I can use the analyze-string to parse this (mostly),
I'm missing a processing model to take care of exceptions.
E.g. xxx.01a is a particular (valid form).
On occasions someone has misnamed the file xxx.ola using o instead
of 0 letter l instead of 1.
I'm missing the nest of cases: My code is shown below.
What's the logic to posively select all the known/valid combinations
are exhausted?
I want to add some form of error markup to identify these rogues.
Valid options include, for regex-group(5)
nnb
nnm
nnl
nnf
lab
TIA, regards DaveP
