The following are some of the limitations of SAX.
No random access to the
document
Because the document is not in memory, you must handle data in the order in which it is processed. As a result, SAX can be difficult to use when the document contains many internal cross-references, such as ID and IDREF attributes.
Difficult to implement complex
searches
It is your responsibility to maintain data structures holding context information that you must retain, such as the attributes of the current element's ancestor.
No SAX implementation in current
browsers
SAX support is not built into Microsoft® Internet Explorer.
