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

Element.hasAttributeNS介绍

[英]Returns true when an attribute with a given local name and namespace URI is specified on this element or has a default value, false otherwise.
Per [XML Namespaces] , applications must use the value null as the namespaceURI parameter for methods if they wish to have no namespace.
[中]当在此元素上指定了具有给定本地名称和命名空间URI的属性或具有默认值时，返回true，否则返回false。
根据[{$0$}]，如果应用程序希望没有命名空间，则必须将值null用作方法的namespaceURI参数。

代码示例

public String getAttribute(String namespace, String name) {
 if (currentNode == null) {
  return null;
 }
 Element element = (Element) currentNode;
 if (element.hasAttributeNS(namespace, name)) {
  return element.getAttributeNS(namespace, name).trim();
 } else if (applicationNamespace.equals(namespace)
   && element.hasAttributeNS(AttributeResource.RES_AUTO_NS_URI, name)) {
  return element.getAttributeNS(AttributeResource.RES_AUTO_NS_URI, name).trim();
 }
 return null;
}

  }
  // older version of Xerces (I confirmed that the bug is gone with Xerces 2.4.0)
  // have a problem of re-setting the same namespace attribute twice.
  // work around this bug removing it first.
  if (element.hasAttributeNS("http://www.w3.org/2000/xmlns/", qname)) {
    // further workaround for an old Crimson bug where the removeAttribtueNS
    // method throws NPE when the element doesn't have any attribute.
    // to be on the safe side, check the existence of attributes before
    // attempting to remove it.
    // for details about this bug, see org.apache.crimson.tree.ElementNode2
    // line 540 or the following message:
    // https://jaxb.dev.java.net/servlets/ReadMsg?list=users&msgNo=2767
