RapidXML异常

时间：2019-05-13 22:41:54

标签： c++ rapidxml

我正在尝试解析来自另一个XML格式的系统的响应。我决定使用RapidXML作为解析器。一切正常，直到系统报告“ faultResponse”消息。尝试处理“ faultResponse”消息时，出现解析错误

我确保捕获了异常代码，并说这是一个解析错误。 “预期<”。我正在查看发送系统，他们记录了发送的内容，因此我知道它不缺少<。我尝试xmllint验证它是一个好文件，而xmllint说它很好。

从远程系统发送的实际XML

// get message from system and store in variable target
rapidxml::xml_document<> doc;

}

我希望使doc变量具有xml文档的内容，并开始逐步处理它，但是我遇到了解析错误。

1 个答案:

答案 0 :(得分：0)

我做了更多的测试，看来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对其进行测试，并且Rapidxml正常工作。看起来有些东西正在破坏目标变量。
