Hi dev,

I have a problem which I couldn't figure out after through quest.

I have been trying to figure out the constantly the same error in my xml parser. I have following configuration and dealing with file(200MB-4GB) size:

- Python 2.7
- lxml 2.3.1

The problem I understand is there is mismatch in the XML Syntax (start and end). The file is too huge I can't look inside at particular line between 751969:438466. But I tried what a naive do using sed command (sed -n 751969p filename) for specific line. So here are specific line output 751969 and 438466. It clearly shows that element start and end is not matching. But, the problem is I can't open such a huge file and do editing manually.

Note: I have design the validator according to given schema and it shows the same problem.

Question
------------

- **So how can I get rid off from such a error while parsing in future?**

- **Or get get rid off from such an element which is not mandatory in parser?**

Error goes here

    C:\Documents and Settings\****\Desktop>python example.py
        (751969, 438466)
        None
