从/到xml读取/写入换行符
本文关键字:换行符 xml 读取 | 更新日期: 2023-09-27 17:59:05
我使用xml文件来存储一些键/值数据:
<Resource Key="A1" Value="Some text" />
我遇到的问题是,如果数据是多行文本,我将如何在Value中保存/加载数据?
<Resource Key="A2" Value="Some text'nin two lines" />
当显示时,应导致
Some text
in two lines
如果我使用阅读以上资源
XDocument document = XDocument.Load(filePath);
// get all the localized client resource strings
var resource = (from r in document.Descendants("Resource")
where r.Attribute("Key").Value == "A2"
select r).SingleOrDefault();
它将用双反斜杠读取:
Some text''nin two lines.
那么,我如何读取/保存换行符是一些文本,例如,稍后可以在WPF应用程序或web应用程序中显示?
编辑:以下是一个示例(写入正确,读取错误):
<!-- WPF window xaml code -->
<Grid>
<Button Name="btn" Content="Click me" />
</Grid>
// WPF window code behind
public MainWindow()
{
InitializeComponent();
XDocument doc =
new XDocument(
new XElement("Resources",
new XElement("Resource", new XAttribute("Key", "A1"), new XAttribute("Value", @"Some text'nin two lines")))
);
const string fileName = @"D:'test.xml";
doc.Save(fileName);
doc = XDocument.Load(fileName);
IDictionary<string, string> keys = (from c in doc.Descendants("Resource")
select c).ToDictionary(c => c.Attribute("Key").Value, c => c.Attribute("Value").Value);
btn.ToolTip = keys["A1"];
//btn.ToolTip = "Some text'nin two lines"; // if you uncomment this line, it works as expected
}
取消字符串的转换工作
btn.ToolTip = System.Text.RegularExpressions.Regex.Unescape(keys["A1"]);
如果有人知道如何在从xml读取时避免转义(按照原样读取),我会很高兴听到它。
