SAX parsing for cdata tag for large xml file
Here, I have given the code for parsing or reading large xml files using php. Large xml files in php are parsed using this SAX parser. The inner function of php, which gives directly the data of xml, can handle only small xml files (mostly upto 1KB to 50KB). So for parsing large xml files having data like 5MB, 50MB, etc. we have to use this method. The code is given as simple as possible. Just enter your xml file path in 5th line.
