    mxml_node_t *parent,
    int where,
    mxml_node_t *child,
    mxml_node_t *node
);

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.

mxmlDelete

Delete a node and all of its children.

void mxmlDelete (
    mxml_node_t *node
);

If the specified node has a parent, this function first removes the node from its parent using the mxmlRemove function.

mxmlElementDeleteAttr

Delete an attribute.

void mxmlElementDeleteAttr (
    mxml_node_t *node,
    const char *name
);

mxmlElementGetAttr

Get an attribute.

const char * mxmlElementGetAttr (
    mxml_node_t *node,
    const char *name
);

This function returns NULL if the node is not an element or the named attribute does not exist.

mxmlElementGetAttrByIndex

Get an element attribute by index.

const char * mxmlElementGetAttrByIndex (
    mxml_node_t *node,
    int idx,
    const char **name
);

The index ("idx") is 0-based. NULL is returned if the specified index is out of range.

mxmlElementGetAttrCount

Get the number of element attributes.

int  mxmlElementGetAttrCount (
    mxml_node_t *node
);

mxmlElementSetAttr

Set an attribute.

void mxmlElementSetAttr (
    mxml_node_t *node,
    const char *name,
    const char *value
);

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.

mxmlElementSetAttrf

Set an attribute with a formatted value.

void mxmlElementSetAttrf (
    mxml_node_t *node,
    const char *name,
    const char *format,
    ...
);

If the named attribute already exists, the value of the attribute is replaced by the new formatted string. The formatted string value is copied into the element node. This function does nothing if the node is not an element.

    mxml_node_t *top,
    const char *element,
    const char *attr,
    const char *value,
    int descend
);

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.

mxmlFindPath

Find a node with the given path.

mxml_node_t * mxmlFindPath (
    mxml_node_t *top,
    const char *path
);

The "path" is a slash-separated list of element names. The name "" is considered a wildcard for one or more levels of elements. For example, "foo/one/two", "bar/two/one", "/one", and so forth.

The first child node of the found node is returned if the given node has children and the first child is a value node.

mxmlGetInteger

Get the integer value from the specified node or its first child.

int  mxmlGetInteger (
    mxml_node_t *node
);

0 is returned if the node (or its first child) is not an integer value node.

mxmlGetLastChild

Get the last child of an element node.

mxml_node_t * mxmlGetLastChild (
    mxml_node_t *node
);

NULL is returned if the node is not an element node or if the node has no children.

Get the real value for a node or its first child.

double  mxmlGetReal (
    mxml_node_t *node
);

0.0 is returned if the node (or its first child) is not a real value node.

mxmlGetRefCount

Get the current reference (use) count for a node.

int  mxmlGetRefCount (
    mxml_node_t *node
);

The initial reference count of new nodes is 1. Use the mxmlRetain and mxmlRelease functions to increment and decrement a node's reference count.

mxmlGetText

Get the text value for a node or its first child.

const char * mxmlGetText (
    mxml_node_t *node,
    int *whitespace
);

NULL is returned if the node (or its first child) is not a text node. The "whitespace" argument can be NULL.

Note: Text nodes consist of whitespace-delimited words. You will only get single words of text when reading an XML file with MXML_TEXT nodes. If you want the entire string between elements in the XML file, you MUST read the XML file with MXML_OPAQUE nodes and get the resulting strings using the mxmlGetOpaque function instead.

mxmlGetType

Get the node type.

mxml_type_t  mxmlGetType (
    mxml_node_t *node
);

MXML_IGNORE is returned if "node" is NULL.

);

You should call mxmlIndexReset prior to using this function to get the first node in the index. Nodes are returned in the sorted order of the index.

mxmlIndexFind

Find the next matching node.

mxml_node_t * mxmlIndexFind (
    mxml_index_t *ind,
    const char *element,
    const char *value
);

You should call mxmlIndexReset prior to using this function for the first time with a particular set of "element" and "value" strings. Passing NULL for both "element" and "value" is equivalent to calling mxmlIndexEnum.

mxmlIndexGetCount

Get the number of nodes in an index.

int  mxmlIndexGetCount (
    mxml_index_t *ind
);

mxmlIndexNew

Create a new index.

mxml_index_t * mxmlIndexNew (
    mxml_node_t *node,
    const char *element,
    const char *attr
);

The index will contain all nodes that contain the named element and/or attribute. If both "element" and "attr" are NULL, then the index will contain a sorted list of the elements in the node tree. Nodes are sorted by element name and optionally by attribute value if the "attr" argument is not NULL.

mxmlIndexReset

Reset the enumeration/find pointer in the index and return the first node in the index.

mxml_node_t * mxmlIndexReset (
    mxml_index_t *ind
);

    mxml_node_t *top,
    int fd,
    mxml_load_cb_t cb
);

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
for the entire file. The callback function returns the value type that should be used for child nodes. The constants MXML_INTEGER_CALLBACK, MXML_OPAQUE_CALLBACK, MXML_REAL_CALLBACK, and MXML_TEXT_CALLBACK are defined for loading child (data) nodes of the specified type.

Note: The most common programming error when using the Mini-XML library is to load an XML file using the MXML_TEXT_CALLBACK, which returns inline text as a series of whitespace-delimited words, instead of using the MXML_OPAQUE_CALLBACK which returns the inline text as a single string (including whitespace).

mxmlLoadFile

Load a file into an XML node tree.

mxml_node_t * mxmlLoadFile (
    mxml_node_t *top,
    FILE *fp,
    mxml_load_cb_t cb
);
