◆ rnParse()

template<class TData >
void zypp::xml::rnParse ( const InputStream input_r,
TData &  data_r 
)
inline

Parse xml input_r and store data in data_r.

TData must be defaultconstructible and assignable.

TData::RootNode must be a xml::ParseDef constructible from TData&.

Exceptions
ParseDefExceptionon parse errors.

To parse a xml file like this:

<test>
<setup attr="13">value</setup>
<list name="A"/>
<list name="b"/>
</test>
sat::SolvAttr attr
Definition: PoolQuery.cc:311

You need something like this:

struct XmlData
{
// data
unsigned attr;
std::string value;
std:list<std::string> names;
public:
// Convenience parsing to *this.
void parse( const Pathname & path_r )
{ xml::rnParse( path_r, *this ); }
public:
// Parser description
struct RootNode : public xml::ParseDef
{
RootNode( XmlData & data )
: ParseDef( "test", MANDTAORY )
, _data( data )
{
(*this)
("setup", MANDTAORY,
xml::parseDefAssign( data.value )
( "attr", data.attr ) )
// Each individual list entry is collected locally
// and appended to the list after the node is done.
("list", MULTIPLE_OPTIONAL,
xml::parseDefAssign( "name", _cname )
>> bind( &RootNode::cdone, this, _1 ) )
;
}
void cdone( const xml::Node & node_r )
{
_data.push_back( _cname );
_cname.clear(); // prepare for next
}
private:
XmlData & _data; // stored just because notification callbacks are used.
std::string _cname;
};
};
XmlData xmlData;
xmlData.parse( "/tmp/mytest.xml" );
std::list< PublicKeyData > _data

◆ escape()

detail::EscapedString zypp::xml::escape ( const std::string &  in_r)
