( #3333=superdoc: print w/replies, xml ) Need Help??
I managed to get it out badly with
my @nodes = $tree->findnodes('//tr'); for my $node (@nodes) { @text = $node->findvalues('td') or next; print Dumper \@text;
It is bad, in that I still have no clue what xpath is doing, despite reading documentation on it. It only works because as far as i can see, there is only one table... I am trying to get the following data parsed:
<ul><li>There was registered attempt to establish connection with the +remote host. The connection details are:</li></ul> <p><table class="tbl" cellpadding="5" cellspacing="0"> <tr><td class="cell_1_h">Remote Host</td><td class="cell_2_h">Port Num +ber</td></tr> <tr><td class="cell_1"><td class="cell_2">8091</td><tr> </table></p>
but am having zero luck. I am trying:
my @nodes = $tree->findnodes('//ul'); for my $node ?(@nodes) { my $text2 = $node->findvalue('li') or next; if ($text2 =~ m/connection details are/) { print "$text2\n"; my @text = $node->findvalues('/tr/td'); print @Dumper \@text; } }
The problem is, it clearly finds the li node, matches it, and then tries to run the findvalues against /tr/td. This totally doesn't work.... I have tried '/tr/td', '//tr/td', 'td', and cant get any of them to work at all. The total format of the section, as pasted from above is:
<ul><li>....connection...</li></ul> <p><table> <tr><td>stuff</td><td>stuff2</td></tr> . . . </table> </p>
What the heck is the xpath of the items below that section? Is it even possible to match this? I totally dont understand xpath at all....

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • 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.
