Question

我有一个格式如下的HTML

<article class="cik" id="100">
<a class="ci" href="/abc/1001/STUFF">
              <img alt="Micky Mouse" src="/images/1001.jpg" />
              <span class="mick vtEnabled"></span>

</a>

<div>
         <a href="/abc/1001/STUFF">Micky Mouse</a>
         <span class="FP">$88.00</span>&nbsp;&nbsp;<span class="SP">$49.90</span>

</div>
</article>

在上面的代码中，文章中的标签有一个span class =“mick vtEnabled”，没有标签。我想检查带有指定类名的span标记是否存在于article标记中。我怎么做？我尝试选择（“＆gt; a [href]＆gt; span.mick vtEnabled”）并检查尺寸。对于所有文章标签，它都保持为0，无论其是否设置。任何输入？

从单个article代码开始会很好：

final String test = "<article class=\"cik\" id=\"100\"><a class=\"ci\" href=\"/abc/1001/STUFF\"><img alt=\"Micky Mouse\" src=\"/images/1001.jpg\" /></a><div><a href=\"/abc/1001/STUFF\">Micky Mouse</a><span class=\"FP\">$88.00</span>&nbsp;&nbsp;<span class=\"SP\">$49.90</span></div></article>";
final Elements articles = Jsoup.parse(test).select("article");
for (final Element article : articles) {
    final Elements articleImages = article.select("> a[href] > img[src]");
    for (final Element image : articleImages) {
        System.out.println(image.attr("src"));
    }
    final Elements articleLinks = article.select("> div > a[href]");
    for (final Element link : articleLinks) {
        System.out.println(link.attr("href"));
        System.out.println(link.text());
    }
    final Elements articleFPSpans = article.select("> div > span.FP");
    for (final Element span : articleFPSpans) {
        System.out.println(span.text());
    }
}
    final Elements articleSPSpans = article.select("> div > span.SP");
    for (final Element span : articleSPSpans) {
        System.out.println(span.text());
    }
}

打印：

/images/1001.jpg
/abc/1001/STUFF
Micky Mouse
$88.00
$49.90

Jsoup解析HTML，包括span标签
