I have a question regarding xslt 2.0 transformation and the analyze-string component:
This is what I have tried so far:
<!-->Template for properties<-->
<xsl:template match="UserValue">
<xsl:variable name="TITLE" select="./@title"/>
<xsl:variable name="VALUE" select="./@value"/>
<xsl:analyze-string select="$VALUE" regex="^(\d{4}-\d{2}-\d{2})T(\d{2}:\d{2}:\d{2})$">
<xsl:matching-substring>
<Property>
<Title><xsl:value-of select="$TITLE"/></Title>
<Value>Date:<xsl:value-of select="regex-group(1)"/>Time:<xsl:value-of select="regex-group(2)"/></Value>
</Property>
</xsl:matching-substring>
<xsl:non-matching-substring>
<!-->Set title and value property<-->
<Property>
<Title><xsl:value-of select="$TITLE"/></Title>
<Value><xsl:value-of select="$VALUE"/></Value>
</Property>
</xsl:non-matching-substring>
</xsl:analyze-string>
</xsl:template>
There are datetime strings in following format: YYYY-MM-DDTHH:MM:SS
I used the ^(\d{4}-\d{2}-\d{2})T(\d{2}:\d{2}:\d{2})$ expression to extract two groups. The first group with date and the second group with time and I wanted to add them like it is in the stylesheet.
Now what happens is, that only the non-matching-substring block is executed and not the matching-substring block. I also tried it with the xsl when element and there the matching works but it is not the way I want to do it and also I would like to use the regex-group() function as it would perfectly fit my needs.
I cannot find the error I may have done here. Thank you in advance!
The use of curly braces in the select represent Attribute Value Templates, which means the expression inside the curly braces will be executed to get a value, rather than output literally. So, effectively your regex is being treated as if it was this....
^(\d4-\d2-\d2)T(\d2:\d2:\d2)$
To prevent Attribute Value Templates being used, you have to use double-curly braces
<xsl:analyze-string select="$VALUE" regex="^(\d{{4}}-\d{{2}}-\d{{2}})T(\d{{2}}:\d{{2}}:\d{{2}})$">
