Whether to use SAX or DOM?

[Vinay Kakade]

Hi All,   I am facing a design decision problem regarding whether to use Xerces C++ SAX or DOM parser. The requirements are as follows:   I want to prepare a generalized (nested) linked list (so that it may contain other linked lists) from the data in a configuration file in XML format. Then the user will do various operations on the linked list such as add, modify, delete nodes and can also save the modified data in the linked list back to the configuration file.   I want to know whether I should use SAX or DOM parser in parsing the configuration file. **If I use DOM parser, I need to update the DOM tree for each operation on the linked list such that the linked list and the DOM tree are in sync. For saving data to configuration file, I need to traverse the DOM tree and write it to output file. **If I use SAX parser, for saving data to confoguration file, I need to traverse the linked list and generate XML from it.   Please let me know which parser should I use from the ease of implementation and efficiency point of view.   Thanks in advance, -Vinay Kakade
