什么API能够解决这样的问题？xml节点和schema绑定验证？

[steeven]

动态给定一个schema
1. 能根据其验证已有的xml
2. 能根据schema的任意xpath生成对应的空的xml节点
3. xml的每个节点取出后改变内容可以根据原来的schema验证自己或者验证所有子节点．

或者说拿一个xml文档验证，出错了能知道哪个节点出错．

据说MSXML4.0可以..但我没有试过 -_-!

JavaTM Architecture for XML Binding
README
Specification Version: 1.0
Reference Implementation (RI) Version: 1.0

JavaTM Architecture for XML Binding (JAXB) provides an API and tools that automate the mapping between XML documents and Java objects.

JAXB makes XML easy to use by compiling an XML schema into one or more Java technology classes. The combination of the schema derived classes and the binding framework enable one to perform the following operations on an XML document:


unmarshal XML content into a Java representation
access, update and validate the Java representation against schema constraints
marshal the Java representation of the XML content into XML content
