如何使用 Symfony2 DomCrawler 组件解析正确描述的 XML 文件?
我需要拆分所有部分并与当前部分一起收集一个内部标签(碑文、p、诗歌等),该部分仅属于本部分。
我有如下描述的标准 FB2 书籍 XML 格式:
<?xml version="1.0" encoding="utf-8"?>
<FictionBook xmlns="http://www.gribuser.ru/xml/fictionbook/2.0" xmlns:l="http://www.w3.org/1999/xlink">
<description></description>
<body>
<section>
<title><p><strong>Level 1, section 1</strong></p></title>
<section>
<title><p><strong>Level 2, section 2</strong></p></title>
<section>
<title><p><strong>Level 3, section 3</strong></p></title>
<p>Level 3, section 3, paragraph 1</p>
<poem>
<stanza>
<v>bla-bla-bla 1</v>
<v>bla-bla-bla 2</v>
<v>bla-bla-bla 3</v>
</stanza>
</poem>
<p>Level3, section 3, paragraph 2</p>
<subtitle><strong>x x x</strong></subtitle>
</section>
<section>
<title><p><strong>Level 3, section 4</strong></p></title>
<p>Level 3, section 4, paragraph 1</p>
<p>Level 3, section 4, paragraph 2</p>
<subtitle><strong>x x x</strong></subtitle>
</section>
<section>
<title><p><strong>Level 3, section 5</strong></p></title>
<p>Level 3, section 5, paragraph 1</p>
<p>Level 3, section 5, paragraph 2</p>
<p>Level 3, section 5, paragraph 3</p>
<empty-line/>

下面的代码不起作用,有人可以帮我解决这个问题吗?顺便说一句,标题解析正确......但部分的标签不......
private function loadBookSections(Crawler $crawler)
{
$sections = $crawler->filter('section')->each(function(Crawler $node) {
$c = $node->filter('section')->reduce(function(Crawler $node, $i) {
return ($i == 0);
});
return array(
'title' => $node->filter('title')->text(),
'inner' => $c->html(),
);
});
echo "*******************************************\n";
foreach($sections as $section ) {
echo ">>> ".$section['title']."\n";
echo "!!! ".$section['inner']."\n";
}
}
并感谢您的帮助!
