Why DOM Parser would take more Memory than SAX parser while they are parsing?..

Answer / sandya

Both SAX and DOM are used to parse the XML document. Both
has advantages and disadvantages and can be used in our
programming depending on the situation

SAX:

1. Parses node by node

2. Doesnt store the XML in memory

3. We cant insert or delete a node

4. Top to bottom traversing

DOM

1. Stores the entire XML document into memory before processing

2. Occupies more memory

3. We can insert or delete nodes

4. Traverse in any direction.

If we need to find a node and doesnt need to insert or
delete we can go with SAX itself otherwise DOM provided we
have more memory.
