[Tutor] finding mismatched or unpaired html tags

[Dinesh B Vadhia]

This is the error and traceback:

Unexpected error opening J:/F2/....html: mismatched tag: line 124, column 8

Traceback (most recent call last):
  File "C:\....py", line 492, in <module>
    raw = extractText(xhtmlfile)
  File "C:\....py", line 334, in extractText
    tree = make_tree(xhtmlfile)
  File "....py", line 169, in make_tree
    return tree
UnboundLocalError: local variable 'tree' referenced before assignment
 

Here is line 124, col 8 and I cannot see any obvious missing/mismatched tags:

"<p>As to the present time I am unable physical and mentally to secure all this information at present.</p>"

It seems like the exception gives you the line number. What kind of
exception is raised? The exception object may contain the line and
column in a more accessible form, so you could catch the exception,
get the line number, then read that line out of the file and show it.
