本文整理了Java中org.n52.security.common.xml.XMLPath类的一些代码示例，展示了XMLPath类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。XMLPath类的具体详情如下：
包路径：org.n52.security.common.xml.XMLPath
类名称：XMLPath

XMLPath介绍

[英]Represents an XPath and its evaluation.

You create a "source" XMLPath by using the XMLPathCtx#findIn methods. From there you can use the

• #node(String)
• #all(String)
• #bool(String)
• #number(String)
• #text(String)
  methods to build a whole xpath. After creation of an whole xpath you can call the get() method of each concrete XMLPath instance, to get the result of the query.

Sample (finds a root node of a document):

XMLPathCtx ctx = XMLPathCtx.createNew() 
.addNamespace("t", "http://tempuri.org/test"); 
Node result = ctx.findIn(document).node("/*").get();

[中]表示XPath及其求值。
您可以使用XMLPathCtx#findIn方法创建一个“源”XMLPath。从那里你可以使用
*#节点（字符串）
*#全部（字符串）
*#布尔（弦）
*#编号（字符串）
*#文本（字符串）
方法来构建一个完整的xpath。创建完整的xpath后，可以调用每个具体XMLPath实例的get（）方法，以获取查询结果。
示例（查找文档的根节点）：

XMLPathCtx ctx = XMLPathCtx.createNew() 
.addNamespace("t", "http://tempuri.org/test"); 
Node result = ctx.findIn(document).node("/*").get();
