ASTNode_t* readMathMLFromString

(

const char *

xml

)

Reads the MathML from the given XML string, constructs a corresponding abstract syntax tree, and returns a pointer to the root of the tree.

Parameters

xml	a string containing a full MathML expression

Returns

the root of an AST corresponding to the given mathematical expression, otherwise NULL is returned if the given string is NULL or invalid.

ASTNode_t* readMathMLFromStringWithNamespaces	(	const char *	xml,
		XMLNamespaces_t *	xmlns
	)

Reads the MathML from the given XML string, constructs a corresponding abstract syntax tree, and returns a pointer to the root of the tree.

Parameters

xml	a string containing a full MathML expression
xmlns	a XMLNamespaces_t object containing namespaces that are considered active during the read e.g. an L3 package namespace

Returns

the root of an AST corresponding to the given mathematical expression, otherwise NULL is returned if the given string is NULL or invalid.

char* writeMathMLToString

(

const ASTNode_t *

node

)

Writes the given ASTNode_t (and its children) to a string as MathML, and returns the string.

Parameters

node	the root of an AST to write out to the stream.

Returns

a string containing the written-out MathML representation of the given AST.

Note

The string is owned by the caller and should be freed (with free()) when no longer needed. NULL is returned if the given argument is NULL.
