I am using XSLT 1.0 I have the following xml document

I'd like to select the value of the CHECK_DIGIT_PACK_BARCODE element that is a sibling of a given PRODUCT_ID

Following Tim's suggestion, here's my XSLT which attempts to provide a value for OuterCartonBarcode by keying from the CHECK_DIGIT_PACK_BARCODE of the ns2:SelectResponse

Your current xpath ends with this...

/*[local-name() = 'CHECK_DIGIT_PACK_BARCODE'[PRODUCT_ID/text()="100000005503"]]

... which does not look correct.

The expression you are looking for is this....

/ns0:Root/InputMessagePart_1/*[local-name() = 'SelectResponse']/*[local-name() = 'SelectResult']/*[*[local-name()= 'PRODUCT_ID']/text()='100000005503']/*[local-name() = 'CHECK_DIGIT_PACK_BARCODE']

Or, to make it a bit more readable, this....

/ns0:Root
/InputMessagePart_1
/*[local-name() = 'SelectResponse']
/*[local-name() = 'SelectResult']
/*[*[local-name()= 'PRODUCT_ID']/text()='100000005503']
/*[local-name() = 'CHECK_DIGIT_PACK_BARCODE']

It would be much better if the expression did not try to ignore the namespaces, but used the relevant prefixes (as happens already with ns0:Root). Then the expression is much simplified

 /ns0:Root/InputMessagePart_1/ns2:SelectResponse/ns2:SelectResult/*[ns2:PRODUCT_ID='100000005503']/ns2:CHECK_DIGIT_PACK_BARCODE

Or better still, define a key like so:

<xsl:key name="barcodes" match="ns2:DW_PACK_BARCODESRECORDSELECT" use="ns2:PRODUCT_ID" />

Then you can write just this...

key('barcodes', '100000005503')/ns2:CHECK_DIGIT_PACK_BARCODE
