1. Dom4j 介绍 Dom4j是开放源代码的解析XML文件的框架，它拥有本地的XPath支持，但是不支持使用XPath选择节点虽然 DOM4J 代表了完全独立的开发结果，但最初，它是JDOM 的一种智能分支。它合并了许多超出基本 XML文档表示的功能，包括集成的 XPath支持、XML Schema 支持以及用于大文档或流化文档的基于事件的处理。它还提供了构建文档表示的选项，它通过 DOM4J API 和标准 DOM 接口具有并行访问功能。从2000下半年开始，它就一直处于开发之中。为支持所有这些功能，DOM4J 使用接口和抽象基本类方法。DOM4J 大量使用了 API 中的 Collections 类，但是在许多情况下，它还提供一些替代方法以允许更好的性能或更直接的编码方法。直接好处是，虽然 DOM4J 付出了更复杂的 API 的代价，但是它提供了比JDOM 大得多的灵活性。在添加灵活性、XPath 集成和对大文档处理的目标时，DOM4J 的目标与 JDOM 是一样的：针对 Java 开发者的易用性和直观操作。它还致力于成为比 JDOM 更完整的解决方案，实现在本质上处理所有Java/XML问题的目标。在完成该目标时，它比JDOM 更少强调防止不正确的应用程序行为。 DOM4J 是一个非常非常优秀的Java XML API，具有性能优异

阅读更多关于 Can we force XmlWriter to issue rather than ?

问题 By default, someXmlWriter.WriteElementString("my-tag", someString); produces <my-tag /> I looked around XmlWriterSettings class for possible options that would force the writer to produce <my-tag></my-tag> instead but didn't find anything. Is there a simple way of forcing the XmlWriter to issuing empty elements with "open tag, close tag" rather than with the short-hand form? Edit : Yes! I realize that with regards to XML validity the two notations are equivalent, valid and all... I'm however
