Detailed Description

This section describes the M2MB APIs for XML module.

XML modules provides APIs to decodes a XML string and fills the parameters in the provided structure. Similarly, it also provides APIs to encode XMLstring from the provided structure. The structure information and the XML tag information are given to the XML module in a proprietary embedded schema format. Each TAG in XML string is defined in a structured format that gives the detail information about it, like the tag name, tag type, info on where to decode and fill the data of the tag, tag data type.

Get node API for XML module.

This function gets the node information from the XML file. It fills the child_node(child node structure) if it finds the tag. The tag name is taken from the parent name element in the child_node

Parameters

[in]	child_node	XML child node details. User has to fill the name of the tag and the API would fill the start and end pointer with in the pPNStart and pPNEnd pointer.
[in]	parent_node_start	The starting address of the XML file.
[in]	parent_node_end	The Ending address of the XML file.
[in]	tag_end	The Ending tag of the XML file.

Returns
