这就是我的xPathNavigator的样子:
<mux:Column Name="id" DisplayMemberBinding="{Binding Path=Id, Mode=OneWay}" Width="100" DisplayName="Header_Id" Property="Id" DataType="s:String" xmlns:mux="http://schemas.microsoft.com/SystemCenter/Common/UI/Views/GridView" />
我想在DisplayMemberBinding属性中读取Path的值。
这就是我的尝试:
xPathNavigator.GetAttribute("DisplayMemberBinding", "") //Gives me {Binding Path=Id, Mode=OneWay}
xPathNavigator.GetAttribute("DisplayMemberBinding/Binding/@Path", "") //Gives me empty string
如何在DisplayMemberBinding属性中获取Path的值?
答案 0 :(得分:1)
使用强>:
xPathNavigator.Evaluate
(@"substring-before(substring-after(@DisplayMemberBinding, 'Path='),
',')"
);
当然,您需要将结果转换为string
。
基于XSLT的验证:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:mux="http://schemas.microsoft.com/SystemCenter/Common/UI/Views/GridView">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/*">
<xsl:value-of select=
"substring-before(substring-after(@DisplayMemberBinding, 'Path='),
',')"/>
</xsl:template>
</xsl:stylesheet>
在提供的XML文档上应用此转换时:
<mux:Column Name="id"
DisplayMemberBinding="{Binding Path=Id, Mode=OneWay}"
Width="100" DisplayName="Header_Id"
Property="Id" DataType="s:String"
xmlns:mux="http://schemas.microsoft.com/SystemCenter/Common/UI/Views/GridView" />
评估XPath表达式并将此评估结果复制到输出中:
Id
