Question

I have an XML file with the following structure:

<tu>
    <tuv xml:lang="EN">
        <seg>XXX</seg>
    </tuv>
    <tuv xml:lang="FR">
        <seg>YYY</seg>
    </tuv>
</tu>
<tu>
    <tuv xml:lang="EN">
        <seg>XXX</seg>
    </tuv>
    <tuv xml:lang="FR">
        <seg>YYY</seg>
    </tuv>
</tu>
...

And I would like to delete the node <tu> when <seg>XXX</seg> is equal to <seg>YYY</seg> from a C# application. I have tried with linq and in some other ways, but I wasn t able to compare those internal valuea and then delete the parent node if necessary.

预祝福!

首先,你的XML是无效的,因此,我添加了<条码>和>;root> node,然后为我工作:

XDocument doc = XDocument.Load("test.xml");

var nodesWithMatchingElements = doc.Root.Elements("tu")
                                   .GroupBy(e => e)
                                   .Select(g => new 
                                    { 
                                       Element = g.Key, 
                                       Count = g.Descendants("seg").Select(x => x.Value).Distinct().Count() 
                                    })
                                   .Where(x => x.Count == 1);

foreach (var node in nodesWithMatchingElements)
    node.Element.Remove();
