XML名称不能以“ =”字符开头

Question

我已经阅读了％字符的similar post，但似乎其他问题可以在标题行中解决。在XML中是否存在某些不允许使用的字符，还是我需要以其他方式设置文档格式（在我的情况下，尝试在C＃中读取文档时，“ =”字符给我带来了麻烦）？

Name cannot begin with the character ' '，也类似，但仍由标题固定。

XElement nodes = XElement.Load(filename);  

XML的结构如下：

<?xml version="1.0" encoding="utf-8"?>
<offer>
  <data id="Salary">
    <ocrstring>which is equal to $60,000.00 if working 40 hours per week</ocrstring>
    <rule>.*(([+-]?\$[0-9]{1,3}(?:,?[0-9]{3})*\.[0-9]{2}))</rule>
    <output></output>
  </data>
  <data id="Hours">
    <ocrstring></ocrstring>
    <rule>"(?<=working).*?(?=hours)"</rule>    <!-- Error Occurring Here -->
    <output>bob</output>
  </data>
  <data id="Location">
    <ocrstring></ocrstring>
    <rule>Regex2</rule>
    <output>LongWindingRoad222</output>
  </data>
</offer>

如何解析XML文档而又无法获取无法以字符“ =”开头的错误

Answer 1

您需要对所有<rule>元素使用CDATA部分。

What does <![CDATA[]]> in XML mean?
