本来想用xpath方式统一获取 cname节点的值，但是第二个<com.domain.Products>节点的<cla__id>却是reference的方式，如何得到其值呢？谢谢。
-------
<list>
<com.domain.Products>
<cla__id>
<cla__id reference=".."/>
<cname>class1</cname>
<id>1</id>
</cla__id>
<name>pname1</name>
<id>1</id>
</com.domain.Products>

<com.domain.Products>
<cla__id reference="../../com.domain.Products/cla__id"/>
<name>pname2</name>
<id>2</id>
</com.domain.Products>
</list>
-------
