Xml文档，转义该字符

发布于 2024-11-17 10:06:03 字数 496 浏览 1 评论 0原文

我有一个 XML 文档，在某些节点中具有段落分隔符，

当我将 XML 加载到 XmlDocument 对象中时，我不再看到该字符。相反，我看到了一个空间。我如何让它显示？

XmlDocument doc = new XmlDocument();
doc.Load(xmlFilePath); 
XmlNodeList nodes = doc.SelectNodes("/catalog/classes"); 
foreach(XmlNode node in nodes) { 
    string category = node["category"]; 
    bool containerSeperator = category.Contains("&#x2029;") // this should return true but it returns false. This category has a paragraph separator
}

原文

I have an XML document that has the paragraph separator character in some nodes as  

When I load XML into an XmlDocument object, I no longer see this character. Instead I see a space. How do I get it to show  ?

XmlDocument doc = new XmlDocument();
doc.Load(xmlFilePath); 
XmlNodeList nodes = doc.SelectNodes("/catalog/classes"); 
foreach(XmlNode node in nodes) { 
    string category = node["category"]; 
    bool containerSeperator = category.Contains(" ") // this should return true but it returns false. This category has a paragraph separator
}

测试#1：

var xmlText = @"<Test>&</Test>";
var xml = XDocument.Parse(xmlText);
var result = xml.Element("Test").Value;

结果不会是&，结果将是"。所以Contains("& ") 永远不会成立。

测试#2：

var xmlText = @"<Test> </Test>";
var xml = XDocument.Parse(xmlText);
var result = Encoding.Unicode.GetBytes(xml.Element("Test").Value);

结果将是两个字节：x20 和 x29，这正是从 XML 读取的内容。因此字节在那里，你只是看不到它们作为这个 Unicode字符不可读。

Test #1:

var xmlText = @"<Test>&</Test>";
var xml = XDocument.Parse(xmlText);
var result = xml.Element("Test").Value;

result will not be &, result will be ". So Contains("&") will never be true.

Test #2:

var xmlText = @"<Test> </Test>";
var xml = XDocument.Parse(xmlText);
var result = Encoding.Unicode.GetBytes(xml.Element("Test").Value);

result will be two bytes: x20 and x29, which is exactly what is read from XML. So the bytes are there you just don't see them as this Unicode character is not readable.
