可以使用jsoup和regex, 推薦使用jsoup!jsoup document:https://jsoup.org/cookbook/in...http://www.open-open.com/jsoup/

import org.jsoup.Jsoup; import org.jsoup.nodes.Document; import org.jsoup.nodes.Element;import java.util.regex.Matcher; import java.util.regex.Pattern;public class Main { public static void main(String[] args) {// 方法１: jsoup String html = '<p class='info-detail-head-classify-subname'><a href='http://www.cgvv.com.cn/wenda/11492.html' target='_blank'>財(cái)富</a></p>';Document doc = Jsoup.parse(html); Element element = doc.getElementById('info_detail_head_classify_type'); System.out.println(element.text());// 方法2: regex Pattern r = Pattern.compile('<a.*>(.*)</a>'); Matcher m = r.matcher(html); if (m.find()) {System.out.println(m.group(1)); }} }回答2：

<a[^>]*>([^<]*)</a>
