Question

这是我尝试检索这些多个元素的两次尝试，第一次只选择第一个框和＆amp;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";
}

如何获得这样的结果：

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"

Answer 1

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：

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"

var items = document.Element("PrintJob")
                    .Element("Page")
                    .Elements()
                    .Select(x => x.Name.LocalName + ": " + (string)x)
                    .ToList();

foreach (var item in items)
    Console.WriteLine(item);

输出：

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"

var items = document.Element("PrintJob")
                    .Element("Page")
                    .Elements()
                    .Select(x => new
                                 {
                                     Box  = (x.Name.LocalName == "Box")
                                          ? (string)x
                                          : null,
                                     Text = (x.Name.LocalName == "Text")
                                          ? (string)x
                                          : null
                                 })
                    .ToList();

foreach (var item in items)
    Console.WriteLine("Box: " + item.Box + " Text: " + item.Text);

输出：

Box: 0000,0000,0190,0135 Text:
Box: 0050,0100,0190,0135 Text:
Box: Text: 0000,0000,"ABCdef123456"
Box: Text: 0000,0000,"ABCdef123456"
Box: Text: 0000,0050,"ABCdef123456"
Box: Text: 0000,0050,"ABCdef123456"

Answer 2

var xmlDoc = document.Root.Descendants("Page")
                          .Elements();
foreach(var x in xmlDoc)
{
    Console.WriteLine(x.Name + ": " + x.Value);
}
