Я хочу извлечь текст только для заголовка Методы объекта узла с веб-страницы. Конкретная часть HMTL выглядит следующим образом:

Node Object Methods
<p>The "DOM" column indicates in which DOM Level the method was introduced.</p>


Method
Description
DOM


    <a href="met_node_appendchild.asp">appendChild()</a>

    1 


    <a href="met_node_clonenode.asp">cloneNode()</a>
    Clones a node
    1 


    <a href="met_node_comparedocumentposition.asp">compareDocumentPosition()</a>

    1 


    getFeature(<span class="parameter">feature</span>,<span class="parameter">version</span>)

    of the specified feature and version
    3 


    getUserData(<span class="parameter">key</span>)

    3 


    <a href="met_node_hasattributes.asp">hasAttributes()</a>

    returns false

В Perl, если я напишу следующее:

 my $data = scraper {
 process "table.reference > tr > td > a", 'renners[]' => 'TEXT';
}

for my $i (0 .. $#{$res2->{renners}}) {
  print $res2->{renners}[$i];
print "\n";
}

Я получаю текст для всех тегов, т.е.

attributes
baseURI
.
.
.
.
insertBefore()

когда мне нужен текст тега<a></a> только для методов объекта Node, т.е.

appendChild()
.
.
.
insertBefore()

Короче говоря, я хочу напечатать только методы объекта NODE. Что я должен изменить в коде?
