Tom BoyceSubject: removing duplicates from xml wtih xslt
Author: Tom Boyce
Date: 16 Jul 2013 07:39 PM
I have a need to remove duplicate values in repeating nodes. I've found several examples around the web and studied them enough to try them in my project. When I do, I get the error: XTSE0010: An xsl:template element must not contain an xsl:key element. I'm uploading the source and xslt that's giving this error.

I feel pretty confident I've recreated the example properly. I'm not sure if this is a code problem or maybe some quirk with SS 2011. I"ve specified 1.0 and the example is for this version.

Thanks in advance for any help.

Tom

You have attached the input document twice but the XSLT is missing.

The error reported by Saxon seems to be pretty clear.

Are you sure that xsl:key is defined as direct child of xsl:stylesheet?

I am not sure what you are trying to output but the XSLT contains several errors

1) on line 5 you have declared xsl:key under xsl:template, and as mentioned in previous post this shoudl be udenr xsl:stylesheet

2) the identity template tries to copy attribute after generating text nodes

3) xsl:copy should wrap all template body


Attached here you can find a syntactically correct version which does not mean that its output is what you want. but this is a far as we can go without seeing the desired result

Thanks for your response. I'm not very practiced at xslt so please be patient.

ok, when I run the changes you make I now get the error: SXXP0003: Error reported by XML parser: Content is not allowed in prolog.

at com.exln.stylus.CSaxon8Driver.doProcessing(CSaxon8Driver.java:281)
at com.exln.stylus.CProcessorDriver.process(CProcessorDriver.java:104)
Vendor_Generic_XML.XML (1, 1)

This is line 1
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:a="http://www.ibm.com/maximo">

I have to have this line in there.
when I run just the generic line for stylesheet i get this error:

SXXP0003: Error reported by XML parser: The prefix "xsl" for element "xsl:stylesheet" is not bound.

at com.exln.stylus.CSaxon8Driver.doProcessing(CSaxon8Driver.java:269)
at com.exln.stylus.CProcessorDriver.process(CProcessorDriver.java:104)


what I am trying to output is an xml file exactly like the input xml except with the duplicate values for the nodes under ABCD_COMPCODE elenent.

As an example in the original xml you have these elements/values where
<ABCD_COMPANYCODE>1223</ABCD_COMPANYCODE>
<ABCD_COMPANYNAME>ABCD Productions</ABCD_COMPANYNAME>

occur more than once. I want the duplicate nodes to be removed:

<ABCD_COMPCODE>
<ABCD_COMPANYCODE>1223</ABCD_COMPANYCODE>
<ABCD_COMPANYNAME>ABCD Productions Inc</ABCD_COMPANYNAME>
</ABCD_COMPCODE>
<ABCD_COMPCODE>
<ABCD_COMPANYCODE>1224</ABCD_COMPANYCODE>
<ABCD_COMPANYNAME>ABCD Regional TV Inc</ABCD_COMPANYNAME>
</ABCD_COMPCODE>
<ABCD_COMPCODE>
<ABCD_COMPANYCODE>1223</ABCD_COMPANYCODE>
<ABCD_COMPANYNAME>ABCD Productions Inc</ABCD_COMPANYNAME>
</ABCD_COMPCODE>
<ABCD_COMPCODE>
<ABCD_COMPANYCODE>1223</ABCD_COMPANYCODE>
<ABCD_COMPANYNAME>ABCD Productions Inc</ABCD_COMPANYNAME>
</ABCD_COMPCODE>

The input document had an extra character at the start of the file which made it not well formed

See solution attached
