有人可以向我解释这个或指向一些好文章吗? (请不要链接到XML-Schema规范 – 我读过那些,我更困惑)
TIA
xsd:anyType is a type,like
xsd:integer (though xsd:anyType is
special in that it can act as a simple
or complex type,and it places
essentially no restrictions on the
tree that it validates — think of it
loosely as the Schema language’s
analog of java.lang.Object).A sample use would be:
<xsd:element name="e" type="xsd:anyType"/>
This would mean that elements named
<e>
can have any content,any
attributes,etc.xs:any is a wildcard,usable as a term
in a content model. For example:
<xsd:complexType name="T"> <xsd:sequence> <xsd:element ref="A"/> <xsd:any /> <xsd:element ref="C"/> </xsd:sequence> </xsd:complexType>
Elements of type T must have content
<A/><???/><C/>
,where<???>
can be
any named element. Now,if you look
really closely there is an
approximation to the deFinition of
xsd:anyType given for reference in the
Recommendation,and it uses an xsd:any
wildcard as the means of saying that
it allows any elements.
另外看看XML Schema。
