Hi grandfather, This is the code which i tried.

require HTML::TokeParser;
$p = HTML::TokeParser->new("output.xml") ||
      die "Can't open: $!";
$p->empty_element_tags(1);
open(FH, "output.xml");
print FH $p;
close FH;
[download]

output.xml

<greeting class="simple">Hello, world!
[download]

The above file is a sample file which i tried to insert the closing tag for the greeting. Actually i have a file which contains 500 lines of text with tagging. for. example in that file i have a tag named <to> but it's not closed. I have to insert the closing tag. This is an example. Thanks for your suggestion.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
