Using a date:difference funtion from exslt.org date.msxsl.xsl with msxsl. If I use string literals, then the function works fine. But if I grab the strings from the xml file and put them into variables, and then use those variables for the 'difference' function, I get the following error:
msxsl.exe dummy.xml dateDifftest.xsl -o diffOut.html
Error occurred while executing stylesheet 'dateDifftest.xsl'.
Code: 0x80020009
Microsoft JScript runtime error
Wrong number of arguments or invalid property assignment
line = 954, col = 3 (line is offset from the start of the script block).
Error returned from property or method call.
I made 3 tests in this xsl. All 3 use the same datetime strings.
First test calls function with string literals. Second test calls function with variables with the strings as their content. Third test - and failing test - pulls the strings from the xml file.
So how is the variables of the 3rd test different from those of the 2nd test?
If I comment out the function call of the 3rd test this is output:
TEST-1
PT2M1S
TEST-2
2011-12-13T16:15:26
2011-12-13T16:17:27
PT2M1S
TEST-3
2011-12-13T16:15:26
2011-12-13T16:17:27
The xsl file:
<?xml version='1.0'?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:date="http://exslt.org/dates-and-times"
>
<xsl:include href="date.msxsl.xsl" />
<!-- msxsl.exe dummy.xml dateDifftest.xsl -o diffOut.html -->
<xsl:template match="/A/B/C">
<TEST1>
TEST-1
<br/>
<xsl:value-of select="date:difference('2011-12-13T16:15:26', '2011-12-13T16:17:27')"/> <!-- outputs "PT2M1S", the difference is 2 mins and 1 sec -->
</TEST1>
<br/>
<TEST2>
TEST-2
<br/>
<xsl:variable name="startTime" select="'2011-12-13T16:15:26'"/>
<xsl:value-of select="$startTime"></xsl:value-of>
<br/>
<xsl:variable name="endTime" select="'2011-12-13T16:17:27'"/>
<xsl:value-of select="$endTime"></xsl:value-of>
<br/>
<xsl:value-of select="date:difference($startTime, $endTime)"/> <!-- also outputs "PT2M1S" -->
</TEST2>
<br/>
<TEST3>
TEST-3
<br/>
<xsl:variable name="startTime" select="start"/>
<xsl:value-of select="$startTime"></xsl:value-of>
<br/>
<xsl:variable name="endTime" select="end"/>
<xsl:value-of select="$endTime"></xsl:value-of>
<br/>
<!-- <xsl:value-of select="date:difference($startTime, $endTime)"/>--> <!-- FAILS HERE -->
</TEST3>
</xsl:template>
Input xml file:
<A>
<B>
<C>
<start>2011-12-13T16:15:26</start>
<end>2011-12-13T16:17:27</end>
</C>
</B>
</A>
Thanks
Looking at the source you have linked to I see
<doc:args>
<doc:arg name="date" type="string" default="''" optional="yes"></doc:arg>
<doc:arg name="date" type="string" default="''" optional="yes"></doc:arg>
</doc:args>
so I would suggest to try to make sure on the XSLT/XPath side to pass string values as arguments
<xsl:variable name="startTime" select="string(start)"/>
<xsl:value-of select="$startTime"></xsl:value-of>
<br/>
<xsl:variable name="endTime" select="string(end)"/>
<xsl:value-of select="$endTime"></xsl:value-of>
<br/>
<xsl:value-of select="date:difference($startTime, $endTime)"/>
