 You load an XML file using the mxmlLoadFilename function:
 
     mxml_node_t *tree;
 
-    tree = mxmlLoadFilename(NULL, "filename.xml",

 Similarly, you save an XML file using the mxmlSaveFilename function:
 
     mxml_node_t *tree;

 You can find a named element/node using the mxmlFindElement function:

 wildcards, e.g.:

-    node = mxmlFindElement(tree, tree, "a", NULL, NULL, MXML_DESCEND);
