Detailed Description

Define a xml node structure to parse.

An xml file like this:

<?xml version="1.0" encoding="UTF-8"?>
<syscontent>
  <ident>
    <name>mycollection</name>
    <version epoch="0" ver="1.0" rel="1"/>
    <description>All the cool stuff...</description>
    <created>1165270942</created>
  </ident>
  <onsys>
    <entry kind="package" name="pax" epoch="0" ver="3.4" rel="12" arch="x86_64"/>
    <entry kind="product" name="SUSE_SLES" epoch="0" ver="10" arch="x86_64"/>
    <entry ...
  </onsys>
</syscontent>

Could be described by:

using namespace xml;
struct SycontentNode : public ParseDef
{
  SycontentNode( Mode mode_r )
  : ParseDef( "syscontent", mode_r )
  {
    (*this)("ident",       OPTIONAL)
           ("onsys",       OPTIONAL)
           ;
    (*this)["ident"]
           ("name",        OPTIONAL)
           ("version",     OPTIONAL)
           ("description", OPTIONAL)
           ("created",     OPTIONAL)
           ;
    (*this)["onsys"]
           ("entry",       MULTIPLE_OPTIONAL)
           ;
  }
};

To parse it using an xml::Reader:

xml::Reader reader( input_r );
SycontentNode rootNode( xml::ParseDef::MANDTAORY );
// Define data consumers here.
rootNode.take( reader );

Whithout data consumers this will just parse the file but not retrieve any data. You may attach a consumer derived from xml::ParseDefConsume to each node:

// Parse Edition from ver/rel/eopch attributes.
struct ConsumeEdition : public ParseDefConsume
{
  ConsumeEdition( Edition & value_r )
  : _value( & value_r )
  {}
  virtual void start( const Node & node_r )
  {
    *_value = Edition( node_r.getAttribute("ver").asString(),
                       node_r.getAttribute("rel").asString(),
                       node_r.getAttribute("epoch").asString() );
  }
  Edition *_value;
};

See Also: xml::ParseDefConsume

xml::Reader reader( input_r );
SycontentNode rootNode( xml::ParseDef::MANDTAORY );
// Define data consumers here.
Edition _edition;
rootNode["ident"]["version"].setConsumer
( new ConsumeEdition( _edition ) );
rootNode.take( reader );

That's just one way to collect the data. You could as well use a xml::ParseDefConsumeCallback, and redirect the start call to some arbitrary function or method.

ParseDef & zypp::xml::ParseDef::addNode ( ParseDef & subnode_r )

Add subnode definition.

Note: As ParseDef copies share their implementation you can not add the same subnode to multiple parents.

Returns: *this.

Exceptions

ParseDefBuildException if a subnode with the same name is already defined, or if the subnode is already subnode of an other ParseDef.

void zypp::xml::ParseDef::take ( Reader & reader_r )

Parse the node.

This parses the node and all defined subnodes. Unknown subnodes are skipped and leave a warning in the logfile.

Precondition: Current node must be XML_READER_TYPE_ELEMENT matching this ParseDefs name.

Postcondition: All data parsed. At the corresponding end node. (XML_READER_TYPE_END_ELEMENT or atill at the same node, if it'a an empty element <node />).

Exceptions

ParseDefException on error.
