xml 文件解析
在用bcb 的xml data binding向导 从一个xml schema文件xx.xsd，用于生成cpp文件，解析根据xx.xsd生成的xml时，遇到当xml文件的element不在同一个namespace的时候，只解析与root element相同namespace的那些element
比如xml文件如下：
<rs:SubmitObjectsRequest
xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance "
xmlns:rs= "urn:oasis:names:xsd:2.1 "
xmlns:rim= "urn:oasis:names:rim:xsd:2.1 "
xmlns= "urn:oasis:names:rim:xsd:2.1 "
xsi:schemaLocation= "urn:oasis:names:xsd:2.1 rs.xsd ">
<LeafRegistryObjectList>
<ObjectRef id= "urn:uuid:7edca82f-054d-47f2-a032-9b2a5b518fff "/>
<ObjectRef id= "urn:uuid:a54d6aa5-d40d-43f9-88c5-b4633d873bdd "/>
</LeafRegistryObjectList>
</rs:SubmitObjectsRequest>
SubmitObjectsRequest 与 LeafRegistryObjectList 在不同的namespace，解析时
LeafRegistryObjectList 不能正确读出，是什么原因？

关注，xml data binding 没见过
xml只在.net里面处理过，bcb不会
看楼下的

鹰，当时问我的时候好像说根据xml生成代码呢。原来是找读取XML的类啊？我原来Duceland Desinger自带的代码生成器支持XML parser，不过现在不支持命名空间。
回去我把Duceland Desinger升级一下以便支持命名空间，然后公布reader和writer源代码。

XMLDocument对有名空间的XML情况确实有点问题, 但是有些东东用XML Binding功能又很方便, 真是鲍鱼和熊掌啊:)
