Detailed Description

Parser for YUM primary.xml files (containing package metadata) Use this class as an iterator that produces, one after one, YUMPatchData_Ptr(s) for the XML package elements in the input.

Here's an example:

for (YUMPatchParser iter(anIstream, baseUrl), iter != YUMOtherParser.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().

Member Function Documentation

bool zypp::parser::yum::YUMPatchParser::isInterested ( const xmlNodePtr  nodePtr  )  [private, virtual]

filter for the xml nodes The derived class decides which xml nodes it is actually interested in.

For each that is selected, process() will be called an the resulting ENTRYTYPE object used as the next value for the iterator. Documentation for the node structure can be found in the libxml2 documentation. Have a look at LibXMLHelper to access node attributes and contents.

Parameters:
nodePtr points to the xml node in question. Only the node is available, not the subtree. See libxml2 documentation.
Returns:
true if interested

Implements zypp::parser::XMLNodeIterator< YUMPatchData_Ptr >.

YUMPatchData_Ptr zypp::parser::yum::YUMPatchParser::process ( const xmlTextReaderPtr  reader  )  [private, virtual]

process an xml node The derived class has to produce the ENTRYTYPE object here.

Details about the xml reader is in the libxml2 documentation. You'll most probably want to use xmlTextReaderExpand(reader) to request the full subtree, and then use the links in the resulting node structure to traverse, and class LibXMLHelper to access the attributes and element contents. fetchNext() cannot throw an error since it will be called in the constructor. Instead, in case of a fundamental syntax error the error is saved and will be thrown with the next checkError().

Parameters:
readerPtr points to the xmlTextReader that reads the xml stream.
Returns:

Implements zypp::parser::XMLNodeIterator< YUMPatchData_Ptr >.
