我要解析的HTML代码片段是这样的:
<ul class="authors">
<li class="author" itemprop="author" itemscope="itemscope" itemtype="http://schema.org/Person">
<a href="/search?facet-creator=%22Charles+L.+Fefferman%22" itemprop="name">Charles L. Fefferman</a>,
</li>
<li class="author" itemprop="author" itemscope="itemscope" itemtype="http://schema.org/Person">
<a href="/search?facet-creator=%22Jos%C3%A9+L.+Rodrigo%22" itemprop="name">José L. Rodrigo</a>
</li>
我想提取整个<a>
元素,但是当我尝试用WWW::Mechanize::TreeBuilder
解析它时,我得到的唯一内容就是作者的名字。所以:
内容我期待:
<a href="/search?facet-creator=%22Charles+L.+Fefferman%22" itemprop="name">Charles L. Fefferman</a>,
<a href="/search?facet-creator=%22Jos%C3%A9+L.+Rodrigo%22" itemprop="name">José L. Rodrigo</a>
内容我收到:
Charles L. Fefferman,
José L. Rodrigo
以下是负责解析此问题的代码:
my $mech = WWW::Mechanize->new();
WWW::Mechanize::TreeBuilder->meta->apply($mech);
$mech->get($addressdio);
my @authors = $mech->look_down('class', 'author');
print "Authors: <br />";
foreach ( @authors ) {
say $_->as_text(), "<br />";
}
我认为这可能与as_text()
有关,而且当CGI获取HTML时它不会将其视为文本。
答案 0 :(得分:3)
我处理它,但完全不同 - 使用HTML :: TagParser:
my $html = HTML::TagParser->new("overwrite.xml");
my @li = $html->getElementsByAttribute('class','author');
foreach(@li){
my $a = $_->firstChild();
my $link = $a->getAttribute('href');
say $_->innerText;
say $link;
}
