Detailed Description

template<class char_type, class super_class>
class irr::io::IIrrXMLReader< char_type, super_class >

Interface providing easy read access to a XML file.

You can create an instance of this reader using one of the factory functions createIrrXMLReader(), createIrrXMLReaderUTF16() and createIrrXMLReaderUTF32(). If using the parser from the Irrlicht Engine, please use IFileSystem::createXMLReader() instead. For a detailed intro how to use the parser, see irrxmlexample and features.

The typical usage of this parser looks like this:

    #include <irrXML.h>
    using namespace irr; // irrXML is located in the namespace irr::io
    using namespace io;

    void main()
    {
        // create the reader using one of the factory functions
        IrrXMLReader* xml = createIrrXMLReader("config.xml");

        if (xml == 0)
            return; // file could not be opened

        // parse the file until end reached
        while(xml->read())
        {
            // based on xml->getNodeType(), do something.
        }

        // delete the xml parser after usage
        delete xml;
    }

See irrxmlexample for a more detailed example.

Member Function Documentation

template<class char_type , class super_class >
virtual unsigned int irr::io::IIrrXMLReader< char_type, super_class >::getAttributeCount ( ) const [pure virtual]

Returns attribute count of the current XML node.

This is usually non null if the current node is EXN_ELEMENT, and the element has attributes.

Returns:
Returns amount of attributes of this xml node.
template<class char_type , class super_class >
virtual const char_type* irr::io::IIrrXMLReader< char_type, super_class >::getAttributeName ( int  idx) const [pure virtual]

Returns name of an attribute.

Parameters:
idx,:Zero based index, should be something between 0 and getAttributeCount()-1.
Returns:
Name of the attribute, 0 if an attribute with this index does not exist.
template<class char_type , class super_class >
virtual const char_type* irr::io::IIrrXMLReader< char_type, super_class >::getAttributeValue ( int  idx) const [pure virtual]

Returns the value of an attribute.

Parameters:
idx,:Zero based index, should be something between 0 and getAttributeCount()-1.
Returns:
Value of the attribute, 0 if an attribute with this index does not exist.
template<class char_type , class super_class >
virtual const char_type* irr::io::IIrrXMLReader< char_type, super_class >::getAttributeValue ( const char_type *  name) const [pure virtual]

Returns the value of an attribute.

Parameters:
name,:Name of the attribute.
Returns:
Value of the attribute, 0 if an attribute with this name does not exist.
template<class char_type , class super_class >
virtual float irr::io::IIrrXMLReader< char_type, super_class >::getAttributeValueAsFloat ( const char_type *  name) const [pure virtual]

Returns the value of an attribute as float.

Parameters:
name,:Name of the attribute.
Returns:
Value of the attribute as float, and 0 if an attribute with this name does not exist or the value could not be interpreted as float.
template<class char_type , class super_class >
virtual float irr::io::IIrrXMLReader< char_type, super_class >::getAttributeValueAsFloat ( int  idx) const [pure virtual]

Returns the value of an attribute as float.

Parameters:
idx,:Zero based index, should be something between 0 and getAttributeCount()-1.
Returns:
Value of the attribute as float, and 0 if an attribute with this index does not exist or the value could not be interpreted as float.
template<class char_type , class super_class >
virtual int irr::io::IIrrXMLReader< char_type, super_class >::getAttributeValueAsInt ( const char_type *  name) const [pure virtual]

Returns the value of an attribute as integer.

Parameters:
nameName of the attribute.
Returns:
Value of the attribute as integer, and 0 if an attribute with this name does not exist or the value could not be interpreted as integer.
template<class char_type , class super_class >
virtual int irr::io::IIrrXMLReader< char_type, super_class >::getAttributeValueAsInt ( int  idx) const [pure virtual]

Returns the value of an attribute as integer.

Parameters:
idx,:Zero based index, should be something between 0 and getAttributeCount()-1.
Returns:
Value of the attribute as integer, and 0 if an attribute with this index does not exist or the value could not be interpreted as integer.
template<class char_type , class super_class >
virtual const char_type* irr::io::IIrrXMLReader< char_type, super_class >::getAttributeValueSafe ( const char_type *  name) const [pure virtual]

Returns the value of an attribute in a safe way.

Like getAttributeValue(), but does not return 0 if the attribute does not exist. An empty string ("") is returned then.

Parameters:
name,:Name of the attribute.
Returns:
Value of the attribute, and "" if an attribute with this name does not exist
template<class char_type , class super_class >
virtual const char_type* irr::io::IIrrXMLReader< char_type, super_class >::getNodeData ( ) const [pure virtual]

Returns data of the current node.

Only valid if the node has some data and it is of type EXN_TEXT, EXN_COMMENT, EXN_CDATA or EXN_UNKNOWN.

template<class char_type , class super_class >
virtual const char_type* irr::io::IIrrXMLReader< char_type, super_class >::getNodeName ( ) const [pure virtual]

Returns the name of the current node.

Only valid, if the node type is EXN_ELEMENT.

Returns:
Name of the current node or 0 if the node has no name.
template<class char_type , class super_class >
virtual EXML_NODE irr::io::IIrrXMLReader< char_type, super_class >::getNodeType ( ) const [pure virtual]

Returns the type of the current XML node.

template<class char_type , class super_class >
virtual ETEXT_FORMAT irr::io::IIrrXMLReader< char_type, super_class >::getParserFormat ( ) const [pure virtual]

Returns format of the strings returned by the parser.

This will be UTF8 for example when you created a parser with IrrXMLReaderUTF8() and UTF32 when it has been created using IrrXMLReaderUTF32. It should not be necessary to call this method and only exists for informational purposes.

template<class char_type , class super_class >
virtual ETEXT_FORMAT irr::io::IIrrXMLReader< char_type, super_class >::getSourceFormat ( ) const [pure virtual]

Returns format of the source xml file.

It is not necessary to use this method because the parser will convert the input file format to the format wanted by the user when creating the parser. This method is useful to get/display additional informations.

template<class char_type , class super_class >
virtual bool irr::io::IIrrXMLReader< char_type, super_class >::isEmptyElement ( ) const [pure virtual]

Returns if an element is an empty element, like <foo />

template<class char_type , class super_class >
virtual bool irr::io::IIrrXMLReader< char_type, super_class >::read ( ) [pure virtual]

Reads forward to the next xml node.

Returns:
Returns false, if there was no further node.
