c++ - Parsing XML file while it is being written in Qt

Question

I have a process that is writing an XML file. I am writing an application that wants to parse the XML that is being written. The constraint here is that I want to parse the XML as it is being written. The XML is not written entirely all at once, and will be written gradually. How can I accomplish this using Qt?

Answer 1

您可以使用QXmlStreamReader完成此操作。如果在您解析时数据用完，它将报告 a QXmlStreamReader::PrematureEndOfDocumentError，但如果发生这种情况，您应该能够等待更多数据。
