2. provide framework for custom curl request bodies using custom/non-standard request methods. This was a real nightmare because curl doesn't actually let you specify a string to send as the request body (except when doing POST). You have to treat it as a file upload using a custom file handler function which provides the actual content in chunks as if it were buffered I/O. 3. item_store and item_store_update now return the item that was stored

* Arguments : $contents - The XML text
|

* $namespaces - true or false include namespace information in the returned array as array elements.

* $priority - Can be 'tag' or 'attribute'. This will change the way the resulting array sturcture. For 'tag', the tags are given more importance.
|

* Return: The parsed XML in an array form. Use print_r() to see the resulting array structure.

split between two encoded words, according
