You can construct a sequence of booleans, in which case you should use
<xsl:sequence select="true()"/> in place of <xsl:value-of select="1"/>, and
then you can use `count($temp_result[.])` and `count($temp_result[not(.)]`
to count the number of true and false items respectively.
Thanks. I'm happy with this.
If you want to construct the variable as a single string, you can use
xsl:value-of as I suggested, but then you must declare the variable
as="xs:string".
Looks like, its not possible to write the XSLT solution for my use case
with this way. Below is my attempt to trying do this,
<xsl:stylesheet version="3.0" xmlns:xsl="
http://www.w3.org/1999/XSL/Transform";
xmlns:xs="
http://www.w3.org/2001/XMLSchema";
exclude-result-prefixes="xs">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/">
<xsl:variable name="temp_result" as="xs:string">
<xsl:analyze-string
select="'abhello1cdehello2fghijklhello3hello4mhello5nhello6'"
regex="hello[1-9]">
<xsl:matching-substring>
<xsl:value-of select="1"/>
</xsl:matching-substring>
<xsl:non-matching-substring>
<xsl:value-of select="0"/>
</xsl:non-matching-substring>
</xsl:analyze-string>
</xsl:variable>
<result>
<xsl:value-of select="count($temp_result)"/>
</result>
</xsl:template>
</xsl:stylesheet>
With above, the XSLT 3.0 processor presents me with following error,
Type error at char 0 in expression in xsl:analyze-string/@select on line 10
column 50 of anl_str_2.xsl:
XTTE0570 A sequence of more than one item is not allowed as the value of
variable
$temp_result ("0", "1")
In template rule with match="/" on line 7 of anl_str_2.xsl
A sequence of more than one item is not allowed as the value of variable
$temp_result ("0", "1")
I think that, as per XSLT 3.0 spec, the child content model
of xsl:matching-substring / xsl:non-matching-substring is a sequence
constructor, which would not allow xsl:analyze-string to return an atomic
value (except in a case, when the returned sequence's size is one).
