我试图用java jsoup库从上面的代码中提取数据，虽然当'Contact'p标签为空时出现错误，'contact'p标签上会显示'Contact Position'如何进行联系列空白时显示空白，并在最后一列保留联系人位置p文本？非常感谢您的帮助。 for（元素d：数据）{

               idrow++;

         String Consumers = d.select("h1").text();
         String CertificateNumberall = d.select("p:eq(1)").text();
         String CertificateNumber = CertificateNumberall.substring(CertificateNumberall.lastIndexOf(":") + 1);
         String DateCertifiedall = d.select("p:eq(2)").text();
         String DateCertified = DateCertifiedall.substring(DateCertifiedall.lastIndexOf(":") + 1);
         String ConsumerCodeAll = d.select("p:eq(3)").text();
         String ConsumerCode = ConsumerCodeAll.substring(ConsumerCodeAll.lastIndexOf(":") + 1);
         String MembershipNumberAll = d.select("p:eq(4)").text();
         String MembershipNumber = MembershipNumberAll.substring(MembershipNumberAll.lastIndexOf(":") + 1);
         String CompanyAddressAll = d.select("p:eq(6)").text();
         String CompanyAddress = CompanyAddressAll.substring(CompanyAddressAll.lastIndexOf(":") + 1);
         String TelephoneAll = d.select("p:eq(8)").text();
         String Telephone = TelephoneAll.substring(TelephoneAll.lastIndexOf(":") + 1);
         String WebsiteAll = d.select("p:eq(9) :not(span)").text();
         String Website = WebsiteAll.substring(WebsiteAll.lastIndexOf(":") + 1);
         String EmailAll = d.select("p:eq(10) span").text();
         String Email = EmailAll.substring(EmailAll.lastIndexOf(":") + 1);
         String ContactAll = d.select("p:eq(11)").text();
         String Contact = ContactAll.substring(ContactAll.lastIndexOf(":") + 1);
         String ContactPositionAll = d.select("p:eq(12)").next("hr").text();
         String ContactPosition = ContactPositionAll.substring(ContactPositionAll.lastIndexOf(":") + 1);

Answer 1

当您想要获得空白数据（String contact = null或String contact = ""）时，请联系＆＃39; p标签是空的。是对的吗？

根据您的报废页面，p元素中没有类或ID。因此，基本上您无法识别特定信息，例如＆＃39;联系人＆＃39;

我的建议是＆＃34;选择包含指定文字的元素＆＃34;。（jsoup API - selector）如果没有，则返回null。

String contact = d.select("p:contains(Contact:)").get(1);

或者您可以使用:matches(regex)

String contact = d.select("p:matches(^Contact:.*)").get(1);

另外，在Java惯例中，Variable应该是初始小写字母，例如＆＃39; contactAll＆＃39;（它由＆＃39;较低的Camel案例＆＃39;调用）。这些文章可能会有所帮助： The Java™ Tutorials- Variables - Naming / Using Java Naming Conventions

快乐的编码！
