Fraser Goffin a écrit : > Has anyone come across a good Java library for comparing XML instances ? > hi, you should consider XUnit : http://reflex.gforge.inria.fr/xunit.html XUnit does the same than JUnit, but if you have to compare 2 XML documents, it might help ; usually you do you own stuff that produce some datas, and as you have prepared the expected datas, you just have to assert that the 2 datas are equals ; this is the same in XUnit, and the 2 datas can be 2 nodes for example : <xunit:test-case name="myTest" label="Testing purchase order"> <!--run your own stuff--> <acme:transform-purchase-order output="result.xml" id="1234"/> <!--retrieve the result and the output expected--> <xcl:parse name="po" source="result.xml"/> <xcl:parse name="oe" source="output-expected.xml"/> <!--check if they are equals--> <xunit:assert-node-equals result="{ $po }" expected="{ $oe }" recurse="true"/> </xunit:test-case> the tool works on the DOM, and it will report each difference found (for example when an attribute is missing, or when an attribute is not expected, or when the attribute values don't match) ; at a given level, if 2 elements don't match, the tool won't look inside their content exemple of report : http://reflex.gforge.inria.fr/xunit.html#checkingTheErrorReport (if you scroll down a little, you'll find an HTML-formatted output) it is simple, but efficient ; the output report contains the canonical path of each node in fault (the canonical path is the XPath expression that starts from the root and descend child from child by naming it and setting its position regarding its parent : e.g. /root[1]/elem[5]/@attr) namespace URIs are supplied if you have any, and they don't clash even if some have been remapped in the documents enjoy ! -- Cordialement, /// (. .) --------ooO--(_)--Ooo-------- | Philippe Poulard | ----------------------------- http://reflex.gforge.inria.fr/ Have the RefleX !
