Here is some XSLT 2.0 solution that should work for the original input you posted:
Code:
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:mf="http://example.com/mf"
version="2.0">
<xsl:param name="input-separators" as="xs:string" select="'~'"/>
<xsl:param name="output-separator" as="xs:string" select="','"/>
<xsl:param name="lf" as="xs:string" select="'
'"/>
<xsl:output method="text"/>
<xsl:function name="mf:make-lines" as="xs:string*">
<xsl:param name="items" as="item()*"/>
<xsl:param name="elements" as="element()*"/>
<xsl:choose>
<xsl:when test="$elements">
<xsl:for-each select="tokenize($elements[1], $input-separators)">
<xsl:sequence select="mf:make-lines(($items, .), $elements[position() gt 1])"/>
</xsl:for-each>
</xsl:when>
<xsl:otherwise>
<xsl:sequence select="concat(string-join($items, $output-separator), $lf)"/>
</xsl:otherwise>
</xsl:choose>
</xsl:function>
<xsl:template match="/">
<xsl:value-of select="mf:make-lines((), RecordSet/Data/*)" separator=""/>
</xsl:template>
</xsl:stylesheet>
When applied to the input
Code:
<RecordSet>
<Data>
<Field1>Field1</Field1>
<Field2>Field2</Field2>
<Field34>Field3~Field4</Field34>
<Field56>Field5~Field6</Field56>
<Field7>Field7</Field7>
<Field89>Field8~Field9</Field89>
<Field10>Field10</Field10>
</Data>
</RecordSet>
the output is
Code:
Field1,Field2,Field3,Field5,Field7,Field8,Field10
Field1,Field2,Field3,Field5,Field7,Field9,Field10
Field1,Field2,Field3,Field6,Field7,Field8,Field10
Field1,Field2,Field3,Field6,Field7,Field9,Field10
Field1,Field2,Field4,Field5,Field7,Field8,Field10
Field1,Field2,Field4,Field5,Field7,Field9,Field10
Field1,Field2,Field4,Field6,Field7,Field8,Field10
Field1,Field2,Field4,Field6,Field7,Field9,Field10

My original code had
Code:
<xsl:variable name="f1v" select="."/>
but you changed it to
Code:
<xsl:variable name="f1v" select="$Data/Audit_Auditees"/>

Thanks Martin for the code. Will try to work on that sample too. But i will have to convert into XSLT 1.0 and then test to see.

Yes, I changed the code back to original. It seems working. I am getting some new errors as below. I am using the source XML from the above post Not sure how to get rid of this error. Appreciate your help
java.lang.RuntimeException: Error: at xsl:for-each on line 14 column 69 of Desktop/Projects/Audit/SPLITT%7E1.XSL:
FORX0003: The regular expression in tokenize() must not be one that matches a zero-length string

at com.exln.stylus.CProcessorDriver.process(CProcesso rDriver.java:104)

The error message means exactly what it says, and it points to the exact location where the error occurs. So you really ought to be able to work this one out for yourself.
The problem is tokenize(X, '|'). Vertical bar is a special character in regular expressions and needs to be escaped with a backslash.

I am acting dumb, i know. I couldnt help myself because i have no previous experience with XSLT. I am really sorry being pain over the weekend.
I have the code running fine. Resulting nothing. No output
HTML Code:

<xsl:for-each select="tokenize($this/MPG_Supplier_Capabilities,',')">
MPG_Supplier_Capabilities is a zero-length string, so tokenize produces an empty sequence, so the code inside this xsl:for-each is executed zero times, so there is no output.

If one tag misses or zero length like MPG_Supplier_Capabilities, nothing gets generated?
If yes, how do we make sure rest continues with out skipping the whole recordSet?

Hi Martin
Thanks for the code. Your example works with the mock up code i created. But when i execute with the real data (Which was posted here in this forum), it won't work.
Because for each field, the separator might be different in real time scenario. Also i have fields before, middle and after tokenize fields. I need more control over to customize i guess. Also using XSLT 1.0.
I am not experience, so i have no idea on how to convert to 1.0
I appreciate your help

Does the code works in XSLT 1.0 compiler straight? Also how to skip the fields those were empty with out resulting into no output.
Also while doing tokenize, i like to replace special char from some of the fields. Like below example, tokenize splits Autitee 1|Title1, i would like to replace PIPE to {//}, please advice
<Audit_Auditees>Auditee 1|Title 1~Auditee 2|Title 2~Auditee 3|Title 3</Audit_Auditees>
Appreciate your great help here.
