Detailed Description
The xml_text_reader_by_node class is used to represent an XML text reader which dispatches nodes to their registered handlers.Definition at line 32 of file by_node.h.
Constructor & Destructor Documentation
| virtual xml_text_reader_by_node::~xml_text_reader_by_node | ( | ) | [virtual] |
The destructor.
| xml_text_reader_by_node::xml_text_reader_by_node | ( | input & | deeper, | |
| bool | validate = false | |||
| ) |
The constructor.
| xml_text_reader_by_node::xml_text_reader_by_node | ( | ) | [private] |
The default constructor. Do not use.
| xml_text_reader_by_node::xml_text_reader_by_node | ( | const xml_text_reader_by_node & | ) | [private] |
The copy constructor. Do not use.
Member Function Documentation
The register_node_handler method is sued to register a node name and a corresponding handler.
- Parameters:
-
name The name of the node to be handled. Nodes are named ratyher like UNIX paths, they are slash separated. E.g. parent/ child/ subchild, etc. NO wildcards are available. handler The object which will adela with the named nodes. Noth that (depending on the DTD) this may be called from more than one instance, but always with begin/end pairs, so it is possible to keep track.
| void xml_text_reader_by_node::process_node | ( | ) | [virtual] |
The process_node method is used to process each node as it is read from the input. Each derived class must supply its own process_node method.
Implements xml_text_reader.
| void xml_text_reader_by_node::process_node_end | ( | bool | empty | ) | [virtual] |
The process_node_end method is only ever called for ELEMENT nodes, and only after all of the attributes have been given to the process_node method.
The default implimentation does nothing.
- Parameters:
-
empty Whether or not the original ELEMENT node was empty.
Reimplemented from xml_text_reader.
| void xml_text_reader_by_node::push_name | ( | const nstring & | name | ) | [private] |
the push_name method is used to tack action when the beginning of an entity or element is seen.
| void xml_text_reader_by_node::pop_name | ( | const nstring & | name | ) | [private] |
the pop_name method is used to tack action when the end of an entity or element is seen.
| void xml_text_reader_by_node::calculate_current_node_handler | ( | ) | [private] |
The calculate_current_node_handler method is used to set the current_node from the name at the top of the names stack.
| xml_text_reader_by_node& xml_text_reader_by_node::operator= | ( | const xml_text_reader_by_node & | ) | [private] |
The assignment operator. Do not use.
