WPF 多层绑定XML
XML文件
<?xml version="1.0" encoding="utf-8" ?>
<a>
<b name="一" code="001">
<c cname="一.1" code="001001" />
<c cname="一.2" code="001002" />
<c cname="一.3" code="001003" />

<b name="二" code="002" />
<c cname="二.1" code="002001" />
<c cname="二.2" code="002002" />

为什么绑定只显示<b name="一" code="001">的子集， <b name="二"/>的不显示？
请高手指教
[解决办法]
试一试这样，修改xpath
<XmlDataProvider x:Key="xmldata" Source="data/x2.xml" XPath="a/b"/>
-->
<XmlDataProvider x:Key="xmldata" Source="data/x2.xml" XPath="a"/>
<TextBlock Grid.Column="0" Grid.Row="0" Text="{Binding XPath=@name}" />
-->
<TextBlock Grid.Column="1" Grid.Row="0" Text="{Binding XPath=b/@code}" />
