Question

我有xml以下，我的目标是给定ProductName（例如Spot）和给定语言例如（“en-gb”）我想要所有翻译。所以在这种情况下（ProductName = Spot和language =“en-gb”）输出应该是TRADE STATUS，TRADE ID，VALUE DATE

我在linq查询下面尝试了但它打印了“ProductType = Spot”的所有翻译，而不是ProductType = Spot和language =“en-gb”的所有翻译

    var qry = doc.Descendants("Product")
    .Where(p => p.Attribute("ProductName").Value == "Spot")
    .Where(p =>   
   p.Element("Fields")
 .Element("Field")
.Element("Translations")
.Element("Translation")
.Attribute("language")
.Value == "en-gb")
.Select(p => new { Text = p.Value });

如果有人可以为上述目标建议linq查询，那将会很棒。

我找到了自己问题的答案，在linq查询工作下面

var qry = doc.Descendants("Product")
    .Where(p=>p.Attribute("ProductName").Value=="Spot").Descendants("Fields").Descendants("Translations").Descendants("Translation")
    .Where(t => t.Attribute("language").Value == "en-gb")
    .Select(t => new { Text = t.Value });
