Hi,
I am just starting learn how to use xml with Java, and decided to use
Xerces-J as my XML parser as it is the one recommended by the book I
am learning from "Java and XML" by Brett McLaughlin.
I have hit serious problems when it comes to trying to use the
SAXParser to validate my xml file, i do this by the below line of code
reader.setFeature("http://xm.org/sax/features/validation";, true)
where "reader" is a XMLReader object, for the exact error returned
please see the attached error message/stack trace.
I don't think my XML file is wrong as nothing is picked up in XMLSpy
(Home Version) it seems to think that the file is perfectly valid.
The bit of the XML file that Xerces seems to think is wrong is:
<book xmlns="http://www.oreilly.com/javaxml2";
xmlns:ora="http://www.oreilly.com";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.oreilly.com/javaxml2 XSD/contents.xsd
http://www.oreilly.com
XSD/contents-ora.xsd"
>
it does not seem to like xmlns:xsi="......
Any help will be greatly appreciated, and if any more information/data
is needed please let me know.
Thanks,
Andy
