本文整理了Java中org.w3c.dom.Node.getNamespaceURI()方法的一些代码示例，展示了Node.getNamespaceURI()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。Node.getNamespaceURI()方法的具体详情如下：
包路径：org.w3c.dom.Node
类名称：Node
方法名：getNamespaceURI

Node.getNamespaceURI介绍

[英]The namespace URI of this node, or null if it is unspecified (see ).
This is not a computed value that is the result of a namespace lookup based on an examination of the namespace declarations in scope. It is merely the namespace URI given at creation time.
For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as Document.createElement(), this is always null.

Note: Per the Namespaces in XML Specification [XML Namespaces] an attribute does not inherit its namespace from the element it is attached to. If an attribute is not explicitly given a namespace, it simply has no namespace.
[中]此节点的命名空间URI，如果未指定，则为null（请参阅）。
这不是一个计算值，它不是基于对范围中的命名空间声明的检查而进行的命名空间查找的结果。它只是创建时给定的名称空间URI。
对于ELEMENT_NODE和ATTRIBUTE_NODE之外的任何类型的节点，以及使用DOM级别1方法创建的节点，例如Document.createElement()，这始终是null。
注意：根据XML规范[XML Namespaces]中的名称空间，属性不会从其附加到的元素继承其名称空间。如果一个属性没有显式地给出名称空间，那么它就没有名称空间。
