Parsing HTML Using HTML::TreeBuilder
I am trying to parse an html file that has several tables. I am able to find the table I need to parse which contains many rows. My task is to find the data in one particular row. Unfortunately, the only way to identify which row, is by an embedded <script>. Here is the row I am trying to find:
Code:
<TR>
<TD width=156 bgColor=#e7e7e7 height=25> </TD>
<TD width=8 background=UI_04.gif height=25> </TD>
<TD colSpan=3 height=25> </TD>
<TD><FONT style="FONT-SIZE: 8pt"><script>Capture(share.ipaddr)</script>:</FONT></TD>
<TD><FONT style="FONT-SIZE: 8pt"><B>74.176.153.107</B></FONT></TD>
<TD width=13 height=25> </TD>
<TD width=15 background=UI_05.gif height=25> </TD></TR>
<TR>
I cannot figure out how to get the text of that script. Here is my code segment:
Code:
my @tables=$html->look_down('_tag','table');
foreach my $table (@tables) {
if (defined($table->attr('id')) && $table->attr('id') eq "AutoNumber9") {
my @tds=$table->look_down('_tag','td');
foreach my $td (@tds) {
my $script=$td->look_down('_tag','script');
if (defined($script)) {
print($script->as_text."\n");
}
}
}
}
While the logic finds the script tags, it appears that the 'as_text' method returns an empty string for them. How can I determine the script text in that row? TIA.
