Subject: [xsl] xsl:analyze-string From: David.Pawson@xxxxxxxxxxx Date: Mon, 2 Aug 2004 08:33:01 +0100 |
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 <xsl:template match="record"> <xsl:analyze-string select="." flags="i" regex= "([0-9]+/[0-9]+/[0-9]+) +([0-9]+:[0-9]+) +([0-9]+) +([0-9]+)\.([0-9a-z]+)" > <xsl:matching-substring> <file> <nm><xsl:value-of select="regex-group(4)"/></nm> <ext><xsl:value-of select="regex-group(5)"/></ext> <xsl:analyze-string select="regex-group(5)" flags="i" regex= "([0-9]{{1,2}})([a-z])"> <xsl:matching-substring> <vol><xsl:value-of select="regex-group(1)"/></vol> <type> <xsl:choose> <xsl:when test="regex-group(2) = 'b' or regex-group(2) = 'B'"> <xsl:text>braille</xsl:text> </xsl:when> <xsl:when test="regex-group(2) = 'm' or regex-group(2) = 'M'"> <xsl:text>Moon</xsl:text> </xsl:when> <xsl:when test="regex-group(2) = 'l' or regex-group(2) = 'L'"> <xsl:text>ATOD</xsl:text> </xsl:when> <xsl:when test="regex-group(2) = 'f' or regex-group(2) = 'F'"> <xsl:text>DiskFile</xsl:text> </xsl:when> <xsl:otherwise> <xsl:value-of select="."/> </xsl:otherwise> </xsl:choose> </type> </xsl:matching-substring> </xsl:analyze-string> <xsl:if test="regex-group(5)='lab'"> <type>label</type> </xsl:if> </file> </xsl:matching-substring> </xsl:analyze-string> </xsl:template> Regards DaveP. **** snip here ***** -- DISCLAIMER: NOTICE: The information contained in this email and any attachments is confidential and may be privileged.
