如何获取"xmlns:XXX"属性是否在SAX中设置setNamespaceAware(true)? [英] How to get "xmlns:XXX" attribute if set setNamespaceAware(true) in SAX?

问题描述

这是我的代码:

path = wsdlPath;
SAXParserFactory saxfac = SAXParserFactory.newInstance();
saxfac.setNamespaceAware(true);
saxfac.setXIncludeAware(true);
saxfac.setValidating(false);
SAXParser saxParser = saxfac.newSAXParser();
saxParser.parse(wsdlPath, this);

设置setNamespaceAware=true后，无法在方法public void startElement(String uri, String localName, String qName, Attributes attributes)的参数attributes中获得xmlns:XXX属性.

After Setting setNamespaceAware=true, I can't get the xmlns:XXX attributes in parameter attributes of method public void startElement(String uri, String localName, String qName, Attributes attributes).

对于以下节点:

<definitions name="Service1"
    targetNamespace="http://www.test.com/service"
    xmlns="http://schemas.xmlsoap.org/wsdl/"
    xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
    xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/"
    xmlns:http="http://schemas.xmlsoap.org/wsdl/http/"
    xmlns:tns="http://www.test.com/">

我只得到name和targetNamespace属性. xmlns，xmlns:wsdl，xmlns:mime，xmlns:http和xmlns:tns在attributes参数中.但是它们不可访问.

I just get name and targetNamespace attribute. xmlns, xmlns:wsdl, xmlns:mime, xmlns:http and xmlns:tns are in the attributes parameter. But they are not accessible.

是否可以使用setNamespaceAware=true并获取节点的所有属性?

Is there any way to use setNamespaceAware=true and get all attributes of a node?

推荐答案

当您的XML解析器支持XML命名空间时，您就不必访问这些属性，因为它们仅定义了短名称用于XML中使用的名称空间.

When your XML parser is XML Namespace aware, then you should not need access to those properties, as they only define the short names for namespaces used in your XML.

在这种情况下，您始终使用其全名(例如http://schemas.xmlsoap.org/wsdl/)来引用名称空间，并且可以忽略它们在XML中别名的短名称(例如wsdl).

In that case you always refer to the name spaces using their full name (e.g. http://schemas.xmlsoap.org/wsdl/) and can ignore what short name they are aliased to in the XML (e.g. wsdl).

Attributes类:

除非将http://xml.org/sax/features/namespace-prefixes功能设置为true(默认为false)，否则它将不包含用作命名空间声明(xmlns*)的属性.

It will [...] not contain attributes used as Namespace declarations (xmlns*) unless the http://xml.org/sax/features/namespace-prefixes feature is set to true (it is false by default).

因此使用 应该可以帮助您获得这些值.

So using saxfac.setFeature("http://xml.org/sax/features/namespace-prefixes", true) should help you get to those values.
