您好Evan，
您可以尝试按如下方式修改XML文件。
< TREENODES>
< TREENODE TEXT =" Document-1" />
< TREENODE TEXT =" Folder-1" EXPANDED =" true">
< TREENODE TEXT =" Document-2" />
< TREENODE TEXT =" Document-3" />
< / TREENODE>
< TREENODE TEXT =" Document-4" />
< / TREENODES> ;
[注意：xml文件中的节点应该以/
结尾，例如
< TREENODE TEXT =" Document-1" / >
和
< TREENODE TEXT =" Folder-1" EXPANDED =" true">
< / TREENODE>
是正确的语法。
另外< TREENODE TEXT =" ;文献-1。" />是一个简短的形式
< TREENODE TEXT =" Document-1">< / TREENODE> ;.
如果您还有其他相关问题请随时与我联系。

Hi Evan,
You may try to modified the XML file as follows.
<TREENODES>
<TREENODE TEXT="Document-1"/>
<TREENODE TEXT="Folder-1" EXPANDED="true">
<TREENODE TEXT="Document-2" />
<TREENODE TEXT="Document-3" />
</TREENODE>
<TREENODE TEXT="Document-4"/>
</TREENODES>
[Note: the node in xml file should end with /
e.g.
<TREENODE TEXT="Document-1"/>
and
<TREENODE TEXT="Folder-1" EXPANDED="true">
</TREENODE>
is correct syntax.
In addition the <TREENODE TEXT="Document-1"/> is the brief form of
<TREENODE TEXT="Document-1"></TREENODE>.
If you have further related question please feel free to contact me.

Peter，
尝试了你推荐的改变，但我仍然得到同样的错误
消息。这也是XML文件的顶部
<？xml version =''1.0''？>
和文件的其余部分：
< TREENODES>
< TREENODE TEXT =" Document-1" />
< TREENODE TEXT =" Folder-1" EXPANDED =" true">
< TREENODE TEXT =" Document-2" />
< TREENODE TEXT =" Document-3" />
< / TREENODE>
< TREENODE TEXT =" Document-4" />
< / TREENODES> ;
还有什么建议吗？

Peter,
Tried the change that you recommended but I still get the same error
message. This is also at the top of the XML file
<?xml version=''1.0''?>
and the rest of the file:
<TREENODES>
<TREENODE TEXT="Document-1"/>
<TREENODE TEXT="Folder-1" EXPANDED="true">
<TREENODE TEXT="Document-2" />
<TREENODE TEXT="Document-3" />
</TREENODE>
<TREENODE TEXT="Document-4"/>
</TREENODES>
any more suggestions?
