  49. Enumerations
  50. ------------
  51. .. _enum_XMLParser_NodeType:
  52. enum **NodeType**:
  53. - **NODE_NONE** = **0** --- There's no node (no file or buffer opened)
  54. - **NODE_ELEMENT** = **1** --- Element (tag)
  55. - **NODE_ELEMENT_END** = **2** --- End of element
  56. - **NODE_TEXT** = **3** --- Text node
  57. - **NODE_COMMENT** = **4** --- Comment node
  58. - **NODE_CDATA** = **5** --- CDATA content
  59. - **NODE_UNKNOWN** = **6** --- Unknown node
  60. Description
  61. -----------
  62. 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.
  63. Method Descriptions
  64. -------------------
  65. .. _class_XMLParser_get_attribute_count:
  66. - :ref:`int<class_int>` **get_attribute_count** **(** **)** const
  67. Get the amount of attributes in the current element.
  68. .. _class_XMLParser_get_attribute_name:
  69. - :ref:`String<class_String>` **get_attribute_name** **(** :ref:`int<class_int>` idx **)** const
  70. Get the name of the attribute specified by the index in ``idx`` argument.
  71. .. _class_XMLParser_get_attribute_value:
  72. - :ref:`String<class_String>` **get_attribute_value** **(** :ref:`int<class_int>` idx **)** const
  73. Get the value of the attribute specified by the index in ``idx`` argument.
  74. .. _class_XMLParser_get_current_line:
  75. - :ref:`int<class_int>` **get_current_line** **(** **)** const
  76. Get the current line in the parsed file (currently not implemented).
  77. .. _class_XMLParser_get_named_attribute_value:
  78. - :ref:`String<class_String>` **get_named_attribute_value** **(** :ref:`String<class_String>` name **)** const
  79. 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.
  80. .. _class_XMLParser_get_named_attribute_value_safe:
  81. - :ref:`String<class_String>` **get_named_attribute_value_safe** **(** :ref:`String<class_String>` name **)** const
  82. 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.
  83. .. _class_XMLParser_get_node_data:
  84. - :ref:`String<class_String>` **get_node_data** **(** **)** const
  85. Get the contents of a text node. This will raise an error in any other type of node.
  86. .. _class_XMLParser_get_node_name:
  87. - :ref:`String<class_String>` **get_node_name** **(** **)** const
  88. Get the name of the current element node. This will raise an error if the current node type is not ``NODE_ELEMENT`` nor ``NODE_ELEMENT_END``
  89. .. _class_XMLParser_get_node_offset:
  90. - :ref:`int<class_int>` **get_node_offset** **(** **)** const
  91. Get the byte offset of the current node since the beginning of the file or buffer.
  92. .. _class_XMLParser_get_node_type:
  93. - :ref:`NodeType<enum_XMLParser_NodeType>` **get_node_type** **(** **)**
  94. Get the type of the current node. Compare with ``NODE_*`` constants.
  95. .. _class_XMLParser_has_attribute:
  96. - :ref:`bool<class_bool>` **has_attribute** **(** :ref:`String<class_String>` name **)** const
  97. Check whether or not the current element has a certain attribute.
  98. .. _class_XMLParser_is_empty:
  99. - :ref:`bool<class_bool>` **is_empty** **(** **)** const
  100. Check whether the current element is empty (this only works for completely empty tags, e.g. <element \\>).
  101. .. _class_XMLParser_open:
  102. - :ref:`Error<enum_@GlobalScope_Error>` **open** **(** :ref:`String<class_String>` file **)**
  103. Open a XML file for parsing. This returns an error code.
  104. .. _class_XMLParser_open_buffer:
  105. - :ref:`Error<enum_@GlobalScope_Error>` **open_buffer** **(** :ref:`PoolByteArray<class_PoolByteArray>` buffer **)**
  106. Open a XML raw buffer for parsing. This returns an error code.
  107. .. _class_XMLParser_read:
  108. - :ref:`Error<enum_@GlobalScope_Error>` **read** **(** **)**
  109. Read the next node of the file. This returns an error code.
  110. .. _class_XMLParser_seek:
  111. - :ref:`Error<enum_@GlobalScope_Error>` **seek** **(** :ref:`int<class_int>` position **)**
  112. Move the buffer cursor to a certain offset (since the beginning) and read the next node there. This returns an error code.
  113. .. _class_XMLParser_skip_section:
  114. - void **skip_section** **(** **)**
  115. 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.
