问题


I have a payroll XML file that contains a child element(pay_component_code) for every line item row. I'm provided with a mapping document that contains translation between current codes and future codes, either 1:1 or M:1. The requirement is to convert the xml to pipe delimited text file and also aggregate the amount based on a grouping of person number, effective date and pay component code (future state). The xslt I have seems to work fine for a sample population but however, when I ran the program for another group, it errors with following error: A sequence of more than one item is not allowed as the first argument of concat() (<payCode/>, <payCode/>) Line: 1786 Column: 11 I see it happens when the node in context has more than one child element. Can someone explain what the issue might be? Oxygen editor has not been very helpful as it highlights the entire xml, which is too long to analyse the root issue.

Sample xml: 

<?xml version='1.0' encoding='UTF-8'?>

I don't see a line 1786 in your stylesheet, but assuming that the problem is with

group-by="concat(key('paycode', wd:Pay_Component_Code, $payCodes),
                 wd:Person_Number, wd:Effective_Date)">

it's complaining about the first argument to concat(), saying that it contains a sequence of two payCode elements. But even if it only selected one, this code would be questionable, because the element selected by the key() function would be atomized to get its string value, and the string value of a payCode element isn't anything very meaningful. Perhaps it should be key(...)/@name?

The problem seems to be with your data, not with your code; or rather, it's with the assumptions your code is making about your data, in particular uniqueness of values. I would therefore suggest that the solution lies in validation; define your data more precisely, e.g. with an XSD schema, and validate it before you apply the transformation. Alternatively, you can do a lot of validation with custom XSLT code.
