How can I achieve SPLIT function in XSLT 1.0 - xslt

Question

I have a following scenario. I have a TEAM-MEMBERS node which has name in the format last name, first name
<TEAM-MEMBER><LONG-NAME>Last Name, First Name</LONG-NAME></TEAM-MEMBER>
I want to transform this to
<CONTACT><FIRSTNAME>First Name</FIRSTNAME><LASTNAME>Last Name</LASTNAME></CONTACT>
Basically i want to split the <LONG-NAME> node's value by ,
How can I achieve this using XSLT 1.0
This XSLT will be consumed by BizTalk Server hence i am looking for some XSLT 1.0 solutions only
Thanks

Answer 1

Here is a complete XSLT 1.0 solution that uses a general "split" template that splits a string into multiple substrings, provided a delimiter to designate the boundary between substrings:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ext="http://exslt.org/common" exclude-result-prefixes="ext">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="TEAM-MEMBER">
<xsl:variable name="vrtfSplitWords">
<xsl:call-template name="split">
<xsl:with-param name="pText" select="."/>
</xsl:call-template>
</xsl:variable>
<xsl:variable name="vSplitWords"
select="ext:node-set($vrtfSplitWords)/*"/>
<CONTACT>
<FIRSTNAME><xsl:value-of select="$vSplitWords[2]"/></FIRSTNAME>
<LASTNAME><xsl:value-of select="$vSplitWords[1]"/></LASTNAME>
</CONTACT>
</xsl:template>
<xsl:template name="split">
<xsl:param name="pText" select="."/>
<xsl:param name="pDelim" select="', '"/>
<xsl:param name="pElemName" select="'word'"/>
<xsl:if test="string-length($pText)">
<xsl:element name="{$pElemName}">
<xsl:value-of select=
"substring-before(concat($pText,$pDelim),
$pDelim
)
"/>
</xsl:element>
<xsl:call-template name="split">
<xsl:with-param name="pText" select=
"substring-after($pText,$pDelim)"/>
<xsl:with-param name="pDelim" select="$pDelim"/>
<xsl:with-param name="pElemName" select="$pElemName"/>
</xsl:call-template>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
When this transformation is applied on the provided XML document:
<TEAM-MEMBER><LONG-NAME>Last Name, First Name</LONG-NAME></TEAM-MEMBER>
the wanted, correct result is produced:
<CONTACT>
<FIRSTNAME>First Name</FIRSTNAME>
<LASTNAME>Last Name</LASTNAME>
</CONTACT>
II. Solution using FXSL
This transformation uses the str-split-to-words template from FXSL:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ext="http://exslt.org/common"
exclude-result-prefixes="ext"
>
<xsl:import href="strSplit-to-Words.xsl"/>
<xsl:output indent="yes" omit-xml-declaration="yes"/>
<xsl:strip-space elements="*"/>
<xsl:output indent="yes" omit-xml-declaration="yes"/>
<xsl:param name="pmaxLines" select="10"/>
<xsl:template match="/">
<xsl:variable name="vwordNodes">
<xsl:call-template name="str-split-to-words">
<xsl:with-param name="pStr" select="/"/>
<xsl:with-param name="pDelimiters"
select="',()'"/>
</xsl:call-template>
</xsl:variable>
<xsl:apply-templates select=
"ext:node-set($vwordNodes)/*[normalize-space()]"/>
</xsl:template>
<xsl:template match="word[normalize-space()][1]">
<FIRSTNAME>
<xsl:value-of select="normalize-space()"/>
</FIRSTNAME>
</xsl:template>
<xsl:template match="word[normalize-space()][2]">
<MIDNAME>
<xsl:value-of select="normalize-space()"/>
</MIDNAME>
</xsl:template>
<xsl:template match="word[normalize-space()][last()]">
<LASTNAME>
<xsl:value-of select="normalize-space(.)"/>
</LASTNAME>
</xsl:template>
</xsl:stylesheet>
when applied to this XML document (made quite more complex):
<TEAM-MEMBER><LONG-NAME>First Name, (Jr.), Last Name</LONG-NAME></TEAM-MEMBER>
the wanted, correct result is produced:
<FIRSTNAME>First Name</FIRSTNAME>
<MIDNAME>Jr.</MIDNAME>
<LASTNAME>Last Name</LASTNAME>
Do Note:
The str-split-to-words template accepts multiple delimiters. Thus in this transformation the delimiters used are: ',', '(' and ')'

Answer 2

You need a recursive named template. Fortunately it's already been written: look for str:tokenize at http://www.exslt.org.

Answer 3

used substring-after() and substring-before() to get around the split
