c# xml multiple elements

这是我在检索这些多个元素的两次尝试，第一次只选择第一个框&第一个文本元素

第二个检索所有，但它们不是单独的变量——

var xmlDoc = document.Root.Elements("Page")
                          .Select(element => new
                          {
                             Box = (string)element.Element("Box"),
                             Text = (string)element.Element("Text"),
                          }).ToList();

var xmlDoc = document.Root.Descendants("Page")
                          .Elements()
                          .Select(x => x.Value)
                          .ToList();

xml示例:

<?xml version="1.0" standalone="yes"?>
<PrintJob>
<Page>
<Box>0000,0000,0190,0135</Box>
<Box>0050,0100,0190,0135</Box>
<Text>0000,0000,"ABCdef123456"</Text>
<Text>0000,0000,"ABCdef123456"</Text>
<Text>0000,0050,"ABCdef123456"</Text>
<Text>0000,0050,"ABCdef123456"</Text>
</Page>
</PrintJob>

循环检索元素:

foreach (var x in xmlDoc)
{
   //result += "box: " + x.Box + "'n";
   //result += "text: " + x.Text + "'n";
   result += "x: " + x + "'n";
}

如何得到这样的结果:

box: 0000,0000,0190,0135
box: 0050,0100,0190,0135
text: 0000,0000,"ABCdef123456"
text: 0000,0000,"ABCdef123456"
text: 0000,0050,"ABCdef123456"
text: 0000,0050,"ABCdef123456"

你在找这样的东西吗?

var page = document.Element("PrintJob")
                   .Element("Page");
var boxes = page.Elements("Box")
                .Select(x => (string)x)
                .ToList();
var texts = page.Elements("Text")
                .Select(x => (string)x)
                .ToList();
foreach (var box in boxes)
    Console.WriteLine("Box: " + box);
foreach (var text in texts)
    Console.WriteLine("Text: " + text);
输出:

                    .Select(x => x.Name.LocalName + ": " + (string)x)
                    .ToList();
