Question

我面临 org.xml.sax.SAXParseException 并希望有人可以向我解释这一点。

堆栈跟踪是

通过谷歌搜索这个异常，我可以找到类似的东西 “org.xml.sax.SAXParseException：字符引用“某些字符”是无效的 XML”，这是有道理的。 但什么是

Failed to parse XML-RPC request: Character reference "&#

It seems missing "is an invalid XML" on the exception message.

谢谢。

Answer 1

无论错误消息显示什么：原因是 xml 文档中存在错误。第 382 列附近的某些内容格式错误，无法解析文档。

我会收到消息，使用一些工具应用适当的缩进（例如 eclipse wst 插件中的 xml 编辑器）并验证文档是否确实格式良好。
