Callback called when a validity error is found. This is a message oriented function similar to an *printf function.

ctx : an xmlValidCtxtPtr validity error context
msg : the string to format *printf like vararg
... : remaining arguments to the format

xmlSplitQName2 ()

xmlChar*    xmlSplitQName2                  (const xmlChar *name,
                                             xmlChar **prefix);

parse an XML qualified name string

[NS 5] QName ::= (Prefix ':')? LocalPart

[NS 6] Prefix ::= NCName

[NS 7] LocalPart ::= NCName

name : an XML parser context
prefix : a xmlChar **
Returns :NULL if not a QName, otherwise the local part, and prefix is updated to get the Prefix if any.

This function returns the list of authorized children to insert within an existing tree while respecting the validity constraints forced by the Dtd. The insertion point is defined using prev and next in the following ways: to insert before 'node': xmlValidGetValidElements(node->prev, node, ... to insert next 'node': xmlValidGetValidElements(node, node->next, ... to replace 'node': xmlValidGetValidElements(node->prev, node->next, ... to prepend a child to 'node': xmlValidGetValidElements(NULL, node->childs, to append a child to 'node': xmlValidGetValidElements(node->last, NULL, ...

pointers to the element names are inserted at the beginning of the array and do not need to be freed.

prev : an element to insert after
next : an element to insert next
list : an array to store the list of child names
max : the size of the array
Returns :the number of element in the list, or -1 in case of error. If the function returns the value max the caller is invited to grow the receiving array and retry.
