XML中的特殊字符

Question

我想解析以下XML

XmlElement costCenterElement2 = doc.CreateElement("CostCenter");
costCenterElement2.InnerXml =
    "<CostCenterNumber>2</CostCenterNumber> <CostCenter>" +
    "G&A: Fin & Acctng" +
    "</CostCenter>";

但我发现了XML Exception

解析EntityName时发生错误.

Answer 1

是的 - 一个&在XML中无效,需要转义为&.

其他字符无效字符及其转义:

• < - <
• > - >
• " - &quote;
• ' - '

以下应该有效:

XmlElement costCenterElement2 = doc.CreateElement("CostCenter");
costCenterElement2.InnerXml =
  "<CostCenterNumber>2</CostCenterNumber> <CostCenter>" +
  "G&amp;A: Fin &amp; Acctng" +
  "</CostCenter>";

但是,你真的应该创建CostCenterNumber和CostCenter作为元素,而不是InnerXml.
