Transformation of text file into an xml using datapower - xslt

Question

I want to transfer a non-xml text file delimited by '|' characters into an xml using Datapower.
Following is file (sample1)
10|20003|24/23/25|23890
Now i have to break this into the following XML
<ResponseType>
<ResCode>10</ResCode>
<Id>20003</Id>
<SoftCode>24/23/25</SoftCode>
<StatusCode>23890</StatusCode>
</ResponseType>
What I did was following--
1>Create a Transform action in the service that will be receiving non-XML requests.
2>Select "Use XSLT specified in this action on a non-XML message" to specify that this is a Binary Transform.
3>Upload the following stylesheet as the Processing Control File.
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:dp="http://www.datapower.com/extensions"
version="1.0">
<dp:input-mapping href="sample1.ffd" type="ffd"/>
<xsl:output method="xml"/>
<xsl:template match="/">
<xsl:copy-of select="ResponseType"/>
<xsl:call-template name="str:tokenize">
<xsl:with-param name="string" select="string" />
</xsl:call-template>
</xsl:template>
<xsl:template name="str:tokenize">
<xsl:with-param name="string" select="">
str:tokenize('string', '|')
</xsl:with param>
</xsl:template>
</xsl:stylesheet>
and here is my sample1.ffd(which I have uploaded in my local:// directory in Datapower
<File name="ResponseType">
<!-- capture all data into this tag -->
<Field name="ResCode/Id/SoftCode/StatusCode" />
</File>
But I am not getting desired output , I think my xslt is quite wrong
What can I do do to get desired output?

Answer 1

In DataPower using FFD the following should work:
1) Add the FFD file (below one of my old education samples):
<File name="CSVFILE">
<Group name="CSVLine" minOccurs="0" maxOccurs="unbounded" delim="\n">
<Field name="id"/>
<Field name="fname" delim=","/>
<Field name="lname" delim=","/>
<Field name="title" delim=","/>
<Field name="dept" delim=","/>
<Field name="org"/>
</Group>
</File>
2) Add the XSLT (this one simply copies the FFD transformed XML to output):
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:dp="http://www.datapower.com/extensions"
version="1.0">
<dp:input-mapping href="CSVFILE.FFD" type="ffd"/>
<!-- This stylesheet copies the input to the output -->
<xsl:output method="xml"/>
<xsl:template match="/">
<xsl:copy-of select="." />
</xsl:template>
</xsl:stylesheet>
3) Send a message:
1,Anders,Wasen,B2B Architect,DataPower Dev,Enfo Zystems
2,Jean-Luc,Piccard,Captain,USS Enterprise,Star Fleet
4) This will result in the following XML:
<?xml version="1.0" encoding="UTF-8"?>
<CSVFILE>
<CSVLine>
<id>1</id>
<fname>Anders</fname>
<lname>Wasen</lname>
<title>B2B Architect</title>
<dept>DataPower Dev,Enfo Zystems</dept>
<org/>
</CSVLine>
<CSVLine>
<id>2</id>
<fname>Jean-Luc</fname>
<lname>Piccard</lname>
<title>Captain</title>
<dept>USS Enterprise,Star Fleet</dept>
<org/>
</CSVLine>
</CSVFILE>
Make sure that you change the XSLT Transform action into "Transform Binary" and set Request Type to "non-xml", else it will not work!
Hope this will help you! :)

I'm not sure how IBM Datapower might solve this problem, but for XSLT, you would at least wrap your input in a XML element:
<Whatever>
10|20003|24/23/25|23890
</Whatever>
And then you could go on with a transformation like follows. The hard part is splitting your text input. In XSLT 1.0, there is no function available for that, so you need a recursive template.
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxml="urn:schemas-microsoft-com:xslt" version="1.0" exclude-result-prefixes="msxml">
<xsl:output method="xml" indent="yes" />
<xsl:template match="/">
<xsl:variable name="tokenized">
<items>
<xsl:call-template name="tokenize">
<xsl:with-param name="string" select="//text()" />
</xsl:call-template>
</items>
</xsl:variable>
<ResponseType>
<ResCode>
<xsl:copy-of select="msxml:node-set($tokenized)/items/item[1]/text()" />
</ResCode>
<Id>
<xsl:copy-of select="msxml:node-set($tokenized)/items/item[2]/text()" />
</Id>
<SoftCode>
<xsl:copy-of select="msxml:node-set($tokenized)/items/item[3]/text()" />
</SoftCode>
<StatusCode>
<xsl:copy-of select="msxml:node-set($tokenized)/items/item[4]/text()" />
</StatusCode>
</ResponseType>
</xsl:template>
<xsl:template name="tokenize">
<xsl:param name="string" />
<xsl:variable name="item" select="normalize-space( substring-before( concat( $string, '|'), '|'))" />
<xsl:if test="$item">
<item>
<xsl:value-of select="$item" />
</item>
<xsl:call-template name="tokenize">
<xsl:with-param name="string" select="substring-after($string,'|')" />
</xsl:call-template>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
