  68. Description
  69. -----------
  70. 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.
  71. Method Descriptions
  72. -------------------
  73. .. _class_XMLParser_method_get_attribute_count:
  74. - :ref:`int<class_int>` **get_attribute_count** **(** **)** const
  75. Get the amount of attributes in the current element.
  76. ----
  77. .. _class_XMLParser_method_get_attribute_name:
  78. - :ref:`String<class_String>` **get_attribute_name** **(** :ref:`int<class_int>` idx **)** const
  79. Get the name of the attribute specified by the index in ``idx`` argument.
  80. ----
  81. .. _class_XMLParser_method_get_attribute_value:
  82. - :ref:`String<class_String>` **get_attribute_value** **(** :ref:`int<class_int>` idx **)** const
  83. Get the value of the attribute specified by the index in ``idx`` argument.
  84. ----
  85. .. _class_XMLParser_method_get_current_line:
  86. - :ref:`int<class_int>` **get_current_line** **(** **)** const
  87. Get the current line in the parsed file (currently not implemented).
  88. ----
  89. .. _class_XMLParser_method_get_named_attribute_value:
  90. - :ref:`String<class_String>` **get_named_attribute_value** **(** :ref:`String<class_String>` name **)** const
  91. 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.
  92. ----
  93. .. _class_XMLParser_method_get_named_attribute_value_safe:
  94. - :ref:`String<class_String>` **get_named_attribute_value_safe** **(** :ref:`String<class_String>` name **)** const
  95. 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.
  96. ----
  97. .. _class_XMLParser_method_get_node_data:
  98. - :ref:`String<class_String>` **get_node_data** **(** **)** const
  99. Get the contents of a text node. This will raise an error in any other type of node.
  100. ----
  101. .. _class_XMLParser_method_get_node_name:
  102. - :ref:`String<class_String>` **get_node_name** **(** **)** const
  103. 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>`
  104. ----
  105. .. _class_XMLParser_method_get_node_offset:
  106. - :ref:`int<class_int>` **get_node_offset** **(** **)** const
  107. Get the byte offset of the current node since the beginning of the file or buffer.
  108. ----
  109. .. _class_XMLParser_method_get_node_type:
  110. - :ref:`NodeType<enum_XMLParser_NodeType>` **get_node_type** **(** **)**
  111. Get the type of the current node. Compare with ``NODE_*`` constants.
  112. ----
  113. .. _class_XMLParser_method_has_attribute:
  114. - :ref:`bool<class_bool>` **has_attribute** **(** :ref:`String<class_String>` name **)** const
  115. Check whether or not the current element has a certain attribute.
  116. ----
  117. .. _class_XMLParser_method_is_empty:
  118. - :ref:`bool<class_bool>` **is_empty** **(** **)** const
  119. Check whether the current element is empty (this only works for completely empty tags, e.g. <element \\>).
  120. ----
  121. .. _class_XMLParser_method_open:
  122. - :ref:`Error<enum_@GlobalScope_Error>` **open** **(** :ref:`String<class_String>` file **)**
  123. Open a XML file for parsing. This returns an error code.
  124. ----
  125. .. _class_XMLParser_method_open_buffer:
  126. - :ref:`Error<enum_@GlobalScope_Error>` **open_buffer** **(** :ref:`PoolByteArray<class_PoolByteArray>` buffer **)**
  127. Open a XML raw buffer for parsing. This returns an error code.
  128. ----
  129. .. _class_XMLParser_method_read:
  130. - :ref:`Error<enum_@GlobalScope_Error>` **read** **(** **)**
  131. Read the next node of the file. This returns an error code.
  132. ----
  133. .. _class_XMLParser_method_seek:
  134. - :ref:`Error<enum_@GlobalScope_Error>` **seek** **(** :ref:`int<class_int>` position **)**
  135. Move the buffer cursor to a certain offset (since the beginning) and read the next node there. This returns an error code.
  136. ----
  137. .. _class_XMLParser_method_skip_section:
  138. - void **skip_section** **(** **)**
  139. 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.
