如何在VB.Net中实现这一点

我的xml

<Integration xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:tsg="http://tsgweb.com" xmlns:IXML="http://tsgweb.com" xmlns:CMCodeQueryHelper="urn:CMCodeQueryHelper">
<Case InternalID="1617095448" ID="12131576" xmlns:user="http://tylertechnologies.com">
    <InterimConditionEvent ID="160850198">
        <OrderDate>08/14/2015</OrderDate>
        <ExpirationDate>08/14/2015</ExpirationDate>
        <TimestampCreate>08/14/2015 11:01:57:700</TimestampCreate>
        <TimestampChange>08/14/2015 11:21:51:623</TimestampChange>
        <Deleted>true</Deleted>
        <InterimCondition>
            <ConditionType Word="DOMNC">Domestic No Contact</ConditionType>
            <EffectiveDate>8/14/2015</EffectiveDate>
            <EndDate>8/21/2015</EndDate>
        </InterimCondition>
    </InterimConditionEvent>
    <InterimConditionEvent ID="160850209">
        <OrderDate>08/14/2015</OrderDate>
        <ExpirationDate>08/14/2015</ExpirationDate>
        <TimestampCreate>08/14/2015 11:22:28:900</TimestampCreate>
        <TimestampChange>08/14/2015 11:31:15:890</TimestampChange>
        <Deleted>true</Deleted>
        <InterimCondition>
            <ConditionType Word="DOMNC">Domestic No Contact</ConditionType>
            <EffectiveDate>8/14/2015</EffectiveDate>
            <EndDate>8/14/2015</EndDate>
        </InterimCondition>
    </InterimConditionEvent>
</Case>

请尝试Linq到XML：

Dim xDoc As XElement = XElement.Load("file.xml")

Dim conditionEvents = xDoc.Element("Case").Elements("InterimConditionEvent")

Dim maxId As String = conditionEvents.Attributes("ID").Max(Function(attr) attr.Value)

Dim eventNode As XElement = (From elem In conditionEvents
                             Where elem.Attribute("ID").Value = maxId
                             Select elem).Single()
