Java 当xml文档具有多层次父文档时，如何解析xml？
我正在尝试解析来自响应的xml流，以填充我的android应用程序中的一些字段。如果响应中有一个关键节点项和多个子项，我可以解析该响应 XML是 我的解析代码是 我的问题从xml成为多层次开始，例如 如何解析上述示例？引用文档 我们推荐XmlPullParser，这是一种高效且可维护的方法 在Android上解析XML 您可以使用xml拉式解析器Java 当xml文档具有多层次父文档时，如何解析xml？,java,android,xml,parsing,Java,Android,Xml,Parsing,我正在尝试解析来自响应的xml流，以填充我的android应用程序中的一些字段。如果响应中有一个关键节点项和多个子项，我可以解析该响应 XML是 我的解析代码是 我的问题从xml成为多层次开始，例如 如何解析上述示例？引用文档 我们推荐XmlPullParser，这是一种高效且可维护的方法 在Android上解析XML 您可以使用xml拉式解析器 public class XMLPullParserHandler { private String text; public X

为什么不使用xml PullParser？我必须在哪里发送URL才能得到响应？@Raghunandan因为你知道我得到的是一个字符串作为响应，那么我可以在setInput中设置字符串而不是inputstream吗？@Saty你需要从URL下载xml并将其作为inputstream传递好的@Raghunandan在我下载xml后我可以这样写吗这InputStream in=IOUtils.toInputStreamstring，UTF-8；好的@Raghunandan我需要你的最后一个帮助…我怎么知道在我的案例项目中有多少个元素将被解析？我没有像你所说的那样得到内部节点值，而且如果有很多项目，那么它只解析一个。我怎样才能解析多个？
