<function name="mxmlAdd"><description>Add a node to a tree.
Adds the specified node to the parent. If the child argument is not
NULL, puts the new node before or after the specified child depending
on the value of the where argument. If the child argument is NULL,
puts the new node at the beginning of the child list (MXML_ADD_BEFORE)
or at the end of the child list (MXML_ADD_AFTER). The constant
MXML_ADD_TO_PARENT can be used to specify a NULL child pointer.</description><argument

<function name="mxmlDelete"><description>Delete a node and all of its children.
If the specified node has a parent, this function first removes the
node from its parent using the mxmlRemove() function.</description><argument

</function>
<function name="mxmlElementGetAttr"><returnvalue><description>Attribute value or NULL</description><type>const
char *</type></returnvalue>
<description>Get an attribute.
This function returns NULL if the node is not an element or the
named attribute does not exist.</description><argument
name="node" direction="I"><type>mxml_node_t *</type><description>Element node</description></argument>
<argument name="name" direction="I"><type>const char *</type><description>Name of attribute</description></argument>
</function>
<function name="mxmlElementSetAttr"><description>Set an attribute.
If the named attribute already exists, the value of the attribute
is replaced by the new string value. The string value is copied
into the element node. This function does nothing if the node is
not an element.</description><argument

</function>
<function name="mxmlFindElement"><returnvalue><description>Element node or NULL</description><type>mxml_node_t
*</type></returnvalue>
<description>Find the named element.
The search is constrained by the name, attribute name, and value; any
NULL names or values are treated as wildcards, so different kinds of
searches can be implemented by looking for all elements of a given name
or all elements with a specific attribute. The descend argument determines
whether the search descends into child nodes; normally you will use
MXML_DESCEND_FIRST for the initial search and MXML_NO_DESCEND to find
additional direct descendents of the node. The top node argument
constrains the search to a particular node's children.</description><argument

<function name="mxmlLoadFile"><returnvalue><description>First node or NULL if the file could not be read.</description><type>mxml_node_t
*</type></returnvalue>
<description>Load a file into an XML node tree.
The nodes in the specified file are added to the specified top node.
If no top node is provided, the XML file MUST be well-formed with a
single parent node like &lt;?xml&gt; for the entire file. The callback
function returns the value type that should be used for child nodes.
If MXML_NO_CALLBACK is specified then all child nodes will be either
MXML_ELEMENT or MXML_TEXT nodes.</description><argument

list. The constant MXML_NO_PARENT can be used to specify that the new
element node has no parent.</description><argument

The new integer node is added to the end of the specified parent's child
list. The constant MXML_NO_PARENT can be used to specify that the new
integer node has no parent.</description><argument

</function>
<function name="mxmlNewOpaque"><returnvalue><description>New node</description><type>mxml_node_t
*</type></returnvalue>
<description>Create a new opaque string.
The new opaque node is added to the end of the specified parent's child
list. The constant MXML_NO_PARENT can be used to specify that the new
opaque node has no parent. The opaque string must be nul-terminated and
is copied into the new node.</description><argument
name="parent" direction="I"><type>mxml_node_t *</type><description>Parent node or MXML_NO_PARENT</description></argument>

<function name="mxmlNewText"><returnvalue><description>New node</description><type>mxml_node_t
*</type></returnvalue>
<description>Create a new text fragment node.
The new text node is added to the end of the specified parent's child
list. The constant MXML_NO_PARENT can be used to specify that the new
text node has no parent. The whitespace parameter is used to specify
whether leading whitespace is present before the node. The text
string must be nul-terminated and is copied into the new node.</description><argument
name="parent" direction="I"><type>mxml_node_t *</type><description>Parent node or MXML_NO_PARENT</description></argument>
