Subject: Re: [xsl] xsl:analyze-string use clarification needed From: "Andrew Welch" <andrew.j.welch@xxxxxxxxx> Date: Tue, 23 Jan 2007 14:58:32 +0000 |
I'm having a problem understanding xsl:analyze-string, or perhaps the problem is with my regex.
I'm working with a VARCHAR2 column in an Oracle database. This column has been "re-purposed" to hold three data items in a formatted structure. I need to inspect this field for data entry errors. One of the most common errors is the failure to include one or more spaces to separate the individual data items.
I have written the test template below. What I expect to see as output is "XY". What I get is "".
Can someone point out my error(s)? Thanks.
<xsl:template match="/"> <xsl:variable name="position-code-candidate"> <xsl:analyze-string select="'XY02/28/2007 L'" regex="^\w+"> <xsl:matching-substring> <xsl:value-of select="regex-group(1)" /> </xsl:matching-substring> </xsl:analyze-string> </xsl:variable> <xsl:value-of select="$position-code-candidate" /> </xsl:template>
If you are using regex-group() then you need to specify a group in your regex using brackets ( ) , just using . if you dont have any groups.
Also, I'm not sure why you expect "XY" using that regex - you should expect "XY02"
