RapidXML异常

Question

我正在尝试解析来自另一个XML系统的响应。我决定使用RapidXML作为我的解析器。一切都很顺利，直到系统报告"faultResponse“消息。当尝试处理"faultResponse“消息时，我得到一个解析错误

我确保我捕获了异常代码，它显示这是一个解析错误。“期望的<”。我正在查看发送系统，他们记录了他们发送的内容，所以我知道它不会遗漏<。我尝试了xmllint来验证它是一个好文件，xmllint说它是好的

从远程系统发送的实际XML

我希望获得doc变量来包含xml文档的内容，并开始处理它，但是我得到了解析错误。

Answer 1

我已经做了更多的测试，看起来XML文件是有效的，并且能够被解析。我创建了一个单独的程序来测试它，而且rapidxml运行得很好。看起来有什么东西破坏了目标变量。
