Enumerations

.. _enum_XMLParser_NodeType:

.. _class_XMLParser_constant_NODE_NONE:

.. _class_XMLParser_constant_NODE_ELEMENT:

.. _class_XMLParser_constant_NODE_ELEMENT_END:

.. _class_XMLParser_constant_NODE_TEXT:

.. _class_XMLParser_constant_NODE_COMMENT:

.. _class_XMLParser_constant_NODE_CDATA:

.. _class_XMLParser_constant_NODE_UNKNOWN:

enum **NodeType**:

- **NODE_NONE** = **0** --- There's no node (no file or buffer opened)

- **NODE_ELEMENT** = **1** --- Element (tag)

- **NODE_ELEMENT_END** = **2** --- End of element

- **NODE_TEXT** = **3** --- Text node

- **NODE_COMMENT** = **4** --- Comment node

- **NODE_CDATA** = **5** --- CDATA content

- **NODE_UNKNOWN** = **6** --- Unknown node

Description
-----------

This class can serve as base to make custom XML parsers. Since XML is a very flexible standard, this interface is low level so it can be applied to any possible schema.

Method Descriptions
-------------------

.. _class_XMLParser_method_get_attribute_count:

- :ref:`int<class_int>` **get_attribute_count** **(** **)** const

Get the amount of attributes in the current element.

----

.. _class_XMLParser_method_get_attribute_name:

- :ref:`String<class_String>` **get_attribute_name** **(** :ref:`int<class_int>` idx **)** const

Get the name of the attribute specified by the index in ``idx`` argument.

----

.. _class_XMLParser_method_get_attribute_value:

- :ref:`String<class_String>` **get_attribute_value** **(** :ref:`int<class_int>` idx **)** const

Get the value of the attribute specified by the index in ``idx`` argument.

----

.. _class_XMLParser_method_get_current_line:

- :ref:`int<class_int>` **get_current_line** **(** **)** const

Get the current line in the parsed file (currently not implemented).

----

.. _class_XMLParser_method_get_named_attribute_value:

- :ref:`String<class_String>` **get_named_attribute_value** **(** :ref:`String<class_String>` name **)** const

Get the value of a certain attribute of the current element by name. This will raise an error if the element has no such attribute.

----

.. _class_XMLParser_method_get_named_attribute_value_safe:

- :ref:`String<class_String>` **get_named_attribute_value_safe** **(** :ref:`String<class_String>` name **)** const

Get the value of a certain attribute of the current element by name. This will return an empty :ref:`String<class_String>` if the attribute is not found.

----

.. _class_XMLParser_method_get_node_data:

- :ref:`String<class_String>` **get_node_data** **(** **)** const

Get the contents of a text node. This will raise an error in any other type of node.

----

.. _class_XMLParser_method_get_node_name:

- :ref:`String<class_String>` **get_node_name** **(** **)** const

Get the name of the current element node. This will raise an error if the current node type is not :ref:`NODE_ELEMENT<class_XMLParser_constant_NODE_ELEMENT>` nor :ref:`NODE_ELEMENT_END<class_XMLParser_constant_NODE_ELEMENT_END>`

----

.. _class_XMLParser_method_get_node_offset:

- :ref:`int<class_int>` **get_node_offset** **(** **)** const

Get the byte offset of the current node since the beginning of the file or buffer.

----

.. _class_XMLParser_method_get_node_type:

- :ref:`NodeType<enum_XMLParser_NodeType>` **get_node_type** **(** **)**

Get the type of the current node. Compare with ``NODE_*`` constants.

----

.. _class_XMLParser_method_has_attribute:

- :ref:`bool<class_bool>` **has_attribute** **(** :ref:`String<class_String>` name **)** const

Check whether or not the current element has a certain attribute.

----

.. _class_XMLParser_method_is_empty:

- :ref:`bool<class_bool>` **is_empty** **(** **)** const

Check whether the current element is empty (this only works for completely empty tags, e.g. <element \\>).

----

.. _class_XMLParser_method_open:

- :ref:`Error<enum_@GlobalScope_Error>` **open** **(** :ref:`String<class_String>` file **)**

Open a XML file for parsing. This returns an error code.

----

.. _class_XMLParser_method_open_buffer:

- :ref:`Error<enum_@GlobalScope_Error>` **open_buffer** **(** :ref:`PoolByteArray<class_PoolByteArray>` buffer **)**

Open a XML raw buffer for parsing. This returns an error code.

----

.. _class_XMLParser_method_read:

- :ref:`Error<enum_@GlobalScope_Error>` **read** **(** **)**

Read the next node of the file. This returns an error code.

----

.. _class_XMLParser_method_seek:

- :ref:`Error<enum_@GlobalScope_Error>` **seek** **(** :ref:`int<class_int>` position **)**

Move the buffer cursor to a certain offset (since the beginning) and read the next node there. This returns an error code.

----

.. _class_XMLParser_method_skip_section:

- void **skip_section** **(** **)**

Skips the current section. If the node contains other elements, they will be ignored and the cursor will go to the closing of the current element.
