解析实体名时发生错误。第1行 [英] an error occurred while parsing entityname. line 1

问题描述

Hello All，



我在解析XML字符串时遇到异常。



这是异常 解析entityname;时发生的错误。第1行 和我使用的XML如下;

Hello All,

I have got an exception while parsing an XML string.

Here is the exception an error occurred while parsing entityname;. line 1 and the XML I have used is as follows ;

<Details CompanyName="Outlook & Outlook Express" ></Details>

代码如下：

StringReader strRdr = new StringReader(textBox1.Text);
XmlDocument xmlDoc = new XmlDocument();
try
{
    xmlDoc.Load(strRdr);
    XmlNode node = xmlDoc.DocumentElement.SelectSingleNode(@"/Details");
}
catch (Exception Ex)
{
    System.Windows.Forms.MessageBox.Show(Ex.Message.ToString(), "XML Parsing");
}

如果有人可以帮我解决这个问题，那就太棒了。



问候

推荐答案

这是因为&在公司名称。在XMLDocument中加载字符串时，它会抛出错误。



您需要在加载之前对其进行编码。以下应该做：

It is because of & in the company name. When the string is being loaded in the XMLDocument it throws the error.

You need to encode it before loading it up. Following should do:

StringReader strRdr = new StringReader("<Details CompanyName=\"Outlook &amp; Outlook Express\" ></Details>");

如果需要，可在需要时将其解码。

If needed, decode it back when needed.
