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.
| nodePtr | points to the xml node in question. Only the node is available, not the subtree. See libxml2 documentation. |

| XMLPatternData_Ptr zypp::parser::xmlstore::XMLPatternParser::process | ( | const xmlTextReaderPtr | readerPtr | ) | [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().
| readerPtr | points to the xmlTextReader that reads the xml stream. |
