and reading the source, and I think this is my best bet.
I'm trying to use the xerces-c library through the Sleepycat DB XML software package, and I
consistently have an exception thrown from the following line in the WFXMLScanner class:
// check for duplicate namespace attributes:
// by checking for qualified names with the same local part and with prefixes
// which have been bound to namespace names that are identical.
XMLAttr* loopAttr;
XMLAttr* curAtt;
for (unsigned int attrIndex=0; attrIndex < attCount-1; attrIndex++) {
loopAttr = fAttrList->elementAt(attrIndex);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
for (unsigned int curAttrIndex = attrIndex+1; curAttrIndex < attCount; curAttrIndex++) {
curAtt = fAttrList->elementAt(curAttrIndex);
if (curAtt->getURIId() == loopAttr->getURIId() &&
XMLString::equals(curAtt->getName(), loopAttr->getName())) {
emitError
(
XMLErrs::AttrAlreadyUsedInSTag
, curAtt->getName()
, elemDecl->getFullName()
);
}
}
}
This is from the scanStartTagNS method in the WFXMLScanner.cpp file. The method
fAttrList->elementAt is throwing an ArrayIndexOutofBoundsException. I realize this has to do with
software besides simply xerces, but just from looking over this method's code, it doesn't look like it
should ever throw an exception right here, regardless of how badly deformed the XML file is. I've
run a few different test programs, and all of them have the same result: I simply can't call the
putDocument method without generating an exception. Here is one small test program that
reproduced the error for me:
#include "dbxml/DbXml.hpp" #include "db_cxx.h" using namespace DbXml;
int main()
{
XmlContainer container(NULL, "test.dbxml");
container.open(NULL, DB_CREATE); XmlDocument document;
document.setContent("<testing><a><b><c></c></b></a></testing>"); try {
container.putDocument(NULL, document);
}
catch (std::exception &e) {
std::cerr << e.what() << std::endl;
}return 0; }
Here is the output:
$ ./add_doc
Error: XML Indexer: Fatal parse error in document '', line 1, char 10. Parser Error Message: An
exception occurred! Type:ArrayIndexOutofBoundsException, Message:The passed index is
past the end of the vector
