从android json响应中的字符串解析html

Question

以下字符串是我从 json 响应的字段之一中检索到的内容

Getting better doesn’t stop because it’s getting colder. The best athletes don’t just overcome the elements, they embrace them with Nike Hyperwarm. Gear up for winter: <a href="/l.php?u=http%3A%2F%2Fwww.nike.com%2Fhyperwarm&amp;h=4AQEBIq17&amp;s=1" rel="nofollow nofollow" target="_blank" onmouseover="LinkshimAsyncLink.swap(this, &quot;http:\/\/www.nike.com\/hyperwarm&quot;);" onclick="LinkshimAsyncLink.swap(this, &quot;\/l.php?u=http\u00253A\u00252F\u00252Fwww.nike.com\u00252Fhyperwarm&amp;h=4AQEBIq17&amp;s=1&quot;);">http://www.nike.com/hyperwarm</a><br/><br/><a href="http://www.facebook.com/photo.php?v=10151882076318445" id="" title="" target="" onclick="" style=""><img class="img" src="http://vthumb.ak.fbcdn.net/hvthumb-ak-ash3/t15/1095964_10151882078663445_10151882076318445_40450_2013_b.jpg" alt="" style="height:90px;" /></a><br/><a href="http://www.facebook.com/photo.php?v=10151882076318445" id="" style="">Winning in a Winter Wonderland</a>

Answer 1

尝试使用jsoup html parsing api 来为html 解析提供专用功能，并且还将提供可扩展的解决方案。

对于您的情况（我转义引号和附加 \ 以使其成为有效的 Java 字符串）：

String str = "Getting better doesn’t stop because it’s getting colder. The best athletes don’t just overcome the elements, they embrace them with Nike Hyperwarm. Gear up for winter: <a href=\"/l.php?u=http%3A%2F%2Fwww.nike.com%2Fhyperwarm&amp;h=4AQEBIq17&amp;s=1\" rel=\"nofollow nofollow\" target=\"_blank\" onmouseover=\"LinkshimAsyncLink.swap(this, &quot;http:\\/\\/www.nike.com\\/hyperwarm&quot;);\" onclick=\"LinkshimAsyncLink.swap(this, &quot;\\/l.php?u=http\u00253A\u00252F\u00252Fwww.nike.com\u00252Fhyperwarm&amp;h=4AQEBIq17&amp;s=1&quot;);\">http://www.nike.com/hyperwarm</a><br/><br/><a href=\"http://www.facebook.com/photo.php?v=10151882076318445\" id=\"\" title=\"\" target=\"\" onclick=\"\" style=\"\"><img class=\"img\" src=\"http://vthumb.ak.fbcdn.net/hvthumb-ak-ash3/t15/1095964_10151882078663445_10151882076318445_40450_2013_b.jpg\" alt=\"\" style=\"height:90px;\" /></a><br/><a href=\"http://www.facebook.com/photo.php?v=10151882076318445\" id=\"\" style=\"\">Winning in a Winter Wonderland</a>\"";
Document doc = Jsoup.parse(str);
Element element = doc.select("img").first();
System.out.println(element.attr("src"));
Element element2 = doc.select("a").first(); // Get the anchor tag element
System.out.println(element2.attr("onclick")); // onclick as attribute for anchor tag

输出；
