QName - xsl是名字空间前缀，template是元素名称，xsl:template 就是一个qname

根据wsdl生成 java代码 ：

%AXIS2_HOME%\bin\wsdl2java -uri "http://fy.webxml.com.cn/webservices/EnglishChinese.asmx?wsdl"  -d adb -s

----------------

Qname这个东东，在使用dom4j的时候，经常见到，可能是自己解析的xml都太简单了，所以没有仔细研究过，就是觉得名字很怪异，在google百度搜索“什么是qname”，居然只有几条没有像样答案的纪录。还好，在国外网站上找到了相关的解释，这下基本明白了。
1.来历：qname是qualified name 的简写
2.构成：由名字空间(namespace)前缀(prefix)以及冒号(:),还有一个元素名称构成
3.举例：
     xmlns="http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"
     version="1.0">

xsl是名字空间前缀，template是元素名称，xsl:template 就是一个qname
4.总结：qname无非是有着特定格式的xml元素，其作用主要是增加了名字空间，比如有同样的元素名称，而名字空间不同的情况。先了解这么多，请大家补充。

原文如下：

A document may contain elements and attributes from more than one namespace URI. Because namespace URIs can be quite lengthy, it is cumbersome to include the complete namespace URI in each element or attribute name.

XML allows a shorthand notation to simplify assigning names to namespaces. You may invent a shortnamespace prefix and associate it with a namespace URI.

For example, suppose your document contains names from both the XSLT and XHTML namespaces. In this situation, it is customary to associate the namespace prefix “xsl” with XSLT. You might use prefix “html” to refer to the XHTML namespace.

A qualified name has three parts:

1. A namespace prefix.

2. A colon character, “:”.

3. A local name that gives the name of the element or attribute within that namespace.

For example, here is a fragment illustrating the use of qualified names:

Element template is in the XSLT namespace, and elementhr is in the HTML namespace.

You can also use an unqualified name, which is just a local name without the namespace prefix. The namespace of such a name is called thedefault namespace.

The association between a namespace prefix and a namespace URI is made with anxmlns attribute located in some element. This attribute can have two forms:

• An attribute named xmlns='nsURI' defines the namespace URI of the default namespace. This namespace is associated with all elements and attributes that have unqualified names.

• An attribute named xmlns:prefix='nsURI' associates the givenprefix with the namespace URInsURI.

Here is an example of a complete document using elements from two namespaces:

In this example, the template element is in the XSLT namespace. Thehr element is in the default namespace, which is associated with the XHTML namespace URI.
