Detailed Description

Parser for YUM filelists files Use this class as an iterator that produces, one after one, YUMFileListData_Ptr(s) for the XML package elements.

Here's an example:

for (YUMFileListParser iter(anIstream, baseUrl), iter != YUMFileListParser.end(), // or: iter() != 0, or ! iter.atEnd() ++iter) { doSomething(*iter) }

The iterator owns the pointer (i.e., caller must not delete it) until the next ++ operator is called. At this time, it will be destroyed (and a new ENTRYTYPE is created.)

If the input is fundamentally flawed so that it makes no sense to continue parsing, XMLNodeIterator will log it and consider the input as finished. You can query the exit status with errorStatus().
