DESCRIPTION
Mini-XML is a small XML parsing library that you can use to read XML
and XML-like data files in your application without requiring large
non-standard libraries. Mini-XML only requires an ANSI C compatible
compiler (GCC works, as do most vendors' ANSI C compilers) and a "make"
program.
Mini-XML provides the following functionality:
* Reading of UTF-8 and UTF-16 and writing of UTF-8 encoded XML files
and strings.
* Data is stored in a linked-list tree structure, preserving the XML
data hierarchy.
* Supports arbitrary element names, attributes, and attribute values
with no preset limits, just available memory.
* Supports integer, real, opaque ("CDATA"), and text data types in
"leaf" nodes.
* Functions for creating, indexing, and managing trees of data.
* "Find" and "walk" functions for easily locating and navigating
trees of data.
Mini-XML doesn't do validation or other types of processing on the data
based upon schema files or other sources of definition information, nor
does it support character entities other than those required by the XML
specification.
USING MINI-XML
Mini-XML provides a single header file which you include:
#include <mxml.h>
Nodes are defined by the "mxml_node_t" structure; the "type" member
defines the node type (element, integer, opaque, real, or text) which
determines which value you want to look at in the "value" union. New
nodes can be created using the "mxmlNewElement()", "mxmlNewInteger()",
"mxmlNewOpaque()", "mxmlNewReal()", and "mxmlNewText()" functions.
Only elements can have child nodes, and the top node must be an
element, usually "?xml".
You load an XML file using the "mxmlLoadFile()" function:
FILE *fp;
mxml_node_t *tree;
fp = fopen("filename.xml", "r");
tree = mxmlLoadFile(NULL, fp, MXML_NO_CALLBACK);
fclose(fp);
Similarly, you save an XML file using the "mxmlSaveFile()" function:
FILE *fp;
mxml_node_t *tree;
fp = fopen("filename.xml", "w");
mxmlSaveFile(tree, fp, MXML_NO_CALLBACK);
fclose(fp);
The "mxmlLoadString()", "mxmlSaveAllocString()", and "mxmlSaveString()"
functions load XML node trees from and save XML node trees to strings:
char buffer[8192];
char *ptr;
mxml_node_t *tree;
...
tree = mxmlLoadString(NULL, buffer, MXML_NO_CALLBACK);
...
mxmlSaveString(tree, buffer, sizeof(buffer),
MXML_NO_CALLBACK);
...
ptr = mxmlSaveAllocString(tree, MXML_NO_CALLBACK);
You can find a named element/node using the "mxmlFindElement()"
function:
mxml_node_t *node = mxmlFindElement(tree, tree, "name",
"attr", "value",
MXML_DESCEND);
The "name", "attr", and "value" arguments can be passed as NULL to act
as wildcards, e.g.:
/* Find the first "a" element */
node = mxmlFindElement(tree, tree, "a", NULL, NULL,
MXML_DESCEND);
/* Find the first "a" element with "href" attribute */
node = mxmlFindElement(tree, tree, "a", "href", NULL,
MXML_DESCEND);
/* Find the first "a" element with "href" to a URL */
node = mxmlFindElement(tree, tree, "a", "href",
"http://www.easysw.com/~mike/mxml/",
MXML_DESCEND);
/* Find the first element with a "src" attribute*/
node = mxmlFindElement(tree, tree, NULL, "src", NULL,
MXML_DESCEND);
/* Find the first element with a "src" = "foo.jpg" */
node = mxmlFindElement(tree, tree, NULL, "src",
"foo.jpg", MXML_DESCEND);
You can also iterate with the same function:
mxml_node_t *node;
for (node = mxmlFindElement(tree, tree, "name", NULL,
NULL, MXML_DESCEND);
node != NULL;
node = mxmlFindElement(node, tree, "name", NULL,
NULL, MXML_DESCEND))
{
... do something ...
}
To find the value of a specific node in the tree, use the
"mxmlFindPath()" function:
mxml_node_t *value = mxmlFindPath(tree, "path/to/*/foo/bar");
The "mxmlGetInteger()", "mxmlGetOpaque()", "mxmlGetReal()", and
"mxmlGetText()" functions retrieve the value from a node:
mxml_node_t *node;
int intvalue = mxmlGetInteger(node);
const char *opaquevalue = mxmlGetOpaque(node);
double realvalue = mxmlGetReal(node);
int whitespacevalue;
const char *textvalue = mxmlGetText(node, &whitespacevalue);
Finally, once you are done with the XML data, use the "mxmlDelete()"
function to recursively free the memory that is used for a particular
node or the entire tree:
mxmlDelete(tree);

FUNCTIONS
mxmlAdd
Add a node to a tree.
void mxmlAdd (
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.
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.
mxmlEntityAddCallback
Add a callback to convert entities to Unicode.
int mxmlEntityAddCallback (
mxml_entity_cb_t cb
);
mxmlEntityGetName
Get the name that corresponds to the character value.
const char * mxmlEntityGetName (
int val
);
If val does not need to be represented by a named entity, NULL is
returned.
mxmlEntityGetValue
Get the character corresponding to a named entity.
int mxmlEntityGetValue (
const char *name
);
The entity name can also be a numeric constant. -1 is returned if the
name is not known.
mxmlEntityRemoveCallback
Remove a callback.
void mxmlEntityRemoveCallback (
mxml_entity_cb_t cb
);
mxmlFindElement
Find the named element.
mxml_node_t * mxmlFindElement (
mxml_node_t *node,
mxml_node_t *top,
const char *name,
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.

mxml_node_t *node
);
NULL is returned if the node is not an element node or if the node has
no children.
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.
mxmlGetNextSibling
Return the node type...
mxml_node_t * mxmlGetNextSibling (
mxml_node_t *node
);
mxmlGetOpaque
Get an opaque string value for a node or its first child.
const char * mxmlGetOpaque (
mxml_node_t *node
);
NULL is returned if the node (or its first child) is not an opaque
value node.
mxmlGetParent
Get the parent node.
mxml_node_t * mxmlGetParent (
mxml_node_t *node
);
NULL is returned for a root node.
mxmlGetPrevSibling

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.
mxmlGetType
Get the node type.
mxml_type_t mxmlGetType (
mxml_node_t *node
);
MXML_IGNORE is returned if "node" is NULL.
mxmlGetUserData
Get the user data pointer for a node.
void * mxmlGetUserData (
mxml_node_t *node
);

);
mxmlIndexEnum
Return the next node in the index.
mxml_node_t * mxmlIndexEnum (
mxml_index_t *ind
);
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
);
This function should be called prior to using mxmlIndexEnum() or
mxmlIndexFind() for the first time.

);
The descend argument controls whether the previous node's last child is
considered to be the previous node. The top node argument constrains
the walk to the node's children.
