Hello Monks,

When compile my perl program, I got an error as 'Memory Stack overflow'. Pls help me to correct this problem.

Please find my codings 

My perl code:--

$file=~s#<tbody>((?:[^<]+|<(?!/?tbody>))+</tbody>(?:\s*<tbody>(?:[^<]+
+|<(?!/?tbody>))+</tbody>)*)#"<tbody>\n".${TableBody(\$1)}."\n</tbody>
+"#gies;

sub TableBody
{
    my ($line) = @_;
    $temp = "$$line";
    $temp =~s#</tbody>$##;
    $temp =~s#\t#</para></entry><entry><para>#g;
    $temp ="<row><entry><para>$temp</para></entry></row>";

    $temp =~s#<tbody>#<row><entry><para>#g;
    $temp =~s#</tbody>#</para></entry></row>#g;
    return \$temp;
}

My input is:--

<tbody>one    two    three</tbody>
<tbody>one    two    three</tbody>
<tbody>one    two    three</tbody>
<tbody>one    two    three</tbody>

My output is:--

<tbody>
<row><entry><para>one</para></entry><entry><para>two</para></entry><en
+try><para>three</para></entry></row>
<row><entry><para>one</para></entry><entry><para>two</para></entry><en
+try><para>three</para></entry></row>
<row><entry><para>one</para></entry><entry><para>two</para></entry><en
+try><para>three</para></entry></row>
<row><entry><para>one</para></entry><entry><para>two</para></entry><en
+try><para>three</para></entry></row>
</tbody>

It works well. But if the number of rows in the input exceeds 25, the "Memory stack overflow" error comes.

Pls help me, how to increase stack memory.

thanks
