Generating 8000 text files from xml files
- by Ray
Hi all, i need to generate the same number of text files as the xml files i have. Within the text files, i need the title and maybe some other tags of it. I can generate text files with the elements i wanted but not all xml files can be generated. Only some of them are generated. Something might be wrong with my parser so help out please thanks.
This is my code. Please have a look and give me suggestions. Thanks in advance.
