Hi,
I am trying to debeg my xslt, that uses EXSLT extensions. I am using EXSLT function, parse-date(). I have Stylusstudio 2008 Enterprise Edition and using XSLT processor Saxon 9.0.0.2.
I have added namespace like this

xmlns:edate="http://exslt.org/dates-and-times"
exclude-result-prefixes="edate"

and in the code using function like

<xsl:variable name="dateField" select="edate:parse-date(text(), 'M/d/yyyy hh:mm:ss tt')"/>

when I debug, I am getting this error,
Error: on line 229 of file:///c:/Mike/PROJEC~1/AETC/XML/TESTIN~3.XSL: Cannot find a matching 2-argument function named {http://exslt.org/dates-and-times}parse-date().

Please advise do I need to change anything in my setup,

Thanks
Mike Hall

Hi Mike,
Saxon doesn't support the parse-date() EXSLT function (see http://www.saxonica.com/documentation/extensions/exslt.html for the complete list of the supported ones). According to the official EXSLT web page [http://www.exslt.org/date/functions/parse-date/date.parse-date.html], there is no XSLT processor supporting it.
I fear you will have to write the parsing code for your specific format by using the string-before/string-after standard functions.

Thanks for your response,

Can you please suggest alternative to parse-date() function.

I have big xslt and need to debug what's happening inside. I can replace parse-date() with some other function and continue to debug. There are few parse-date() functions, I can replace them.

Please suggest alternate function or how can I do that,

Thanks
Mike

Hi Mike,
you can use a template like this:

<xsl:template name="parse-date">
<xsl:param name="date"/>
<xsl:variable name="month" select="substring-before($date, '/')"/>
<xsl:variable name="rest1" select="substring-after($date, '/')"/>
<xsl:variable name="day" select="substring-before($rest1, '/')"/>
<xsl:variable name="rest2" select="substring-after($rest1, '/')"/>
<xsl:variable name="year" select="substring-before($rest2, ' ')"/>
<xsl:variable name="rest3" select="substring-after($rest2, ' ')"/>
<xsl:variable name="hour" select="substring-before($rest3, ':')"/>
<xsl:variable name="rest4" select="substring-after($rest3, ':')"/>
<xsl:variable name="minute" select="substring-before($rest4, ':')"/>
<xsl:variable name="second" select="substring-after($rest4, ':')"/>
<xsl:value-of select="concat($year, '-', $month, '-', $day, 'T', $hour, ':', $minute, ':', $second)"/>
</xsl:template>

(you may want to add some code for error checking and day/month/hour/minute padding)

You can invoke it using

<xsl:call-template name="parse-date">
<xsl:with-param name="date" select="'12/12/2007 15:34:23'"/>
</xsl:call-template>

Hope this helps,
Alberto
