Question

我有xml以下。如果我有FolderName，我可以在数组中获取FileTypeId，EngName，JpnName。例如，如果我有Test2，我想使用XDocument类在字符串数组中获取2，EngName2，JpnName2。

<Row>
    <FolderName>Test1</FolderName>
    <FileTypeId>1</FileTypeId>
    <EngName>EngName1</EngName>
    <JpnName>JpnName1</JpnName>
  </Row>
  <Row>
    <FolderName>Test2</FolderName>
    <FileTypeId>2</FileTypeId>
    <EngName>EngName2</EngName>
    <JpnName>JpnName2</JpnName>
  </Row>
  <Row>
    <FolderName>Test3</FolderName>
    <FileTypeId>3</FileTypeId>
    <EngName>EngName3</EngName>
    <JpnName>JpnName3</JpnName>
  </Row>

Answer 1

你需要主根，

var doc = XDocument.Load("data.xml");


<Rows>
  <Row>
    <FolderName>Test1</FolderName>
    <FileTypeId>1</FileTypeId>
    <EngName>EngName1</EngName>
    <JpnName>JpnName1</JpnName>
  </Row>
  <Row>
    <FolderName>Test2</FolderName>
    <FileTypeId>2</FileTypeId>
    <EngName>EngName2</EngName>
    <JpnName>JpnName2</JpnName>
  </Row>
  <Row>
    <FolderName>Test3</FolderName>
    <FileTypeId>3</FileTypeId>
    <EngName>EngName3</EngName>
    <JpnName>JpnName3</JpnName>
  </Row>
</Rows>

Answer 2

尝试使用LINQ：

XDocument xdoc = XDocument.Load("input.xml");

string yourCondition = "Test2";
var query = from elem in xdoc.Root.Elements("Row")
            where elem.Element("FolderName").Value == yourCondition
            select new
            {
                FileTypeId = elem.Element("FileTypeId").Value,
                EngName = elem.Element("EngName").Value,
                JpnName = elem.Element("JpnName").Value
            };

if (query.Count() > 0)
{
    var result = query.First();

    // You can access the fields through this:
    string engName = result.EngName;
    string fileTypeId = result.FileTypeId;
    string jpnName = result.JpnName;
}

正如“snn brn”指出的那样，你的xml中需要一个Root元素。

使用XDocument类读取数组中的节点值
