Why can't I parse a XML file using QXmlStreamReader from Qt?

阅读更多关于 Why can't I parse a XML file using QXmlStreamReader from Qt?

问题 I'm trying to figure out how QXmlStreamReader works for a C++ application I'm writing. The XML file I want to parse is a large dictionary with a convoluted structure and plenty of Unicode characters so I decided to try a small test case with a simpler document. Unfortunately, I hit a wall.

阅读更多关于 Parse a list of XML fragments with no root element from a stream input

问题 Is it feasible in Java using the SAX api to parse a list of XML fragments with no root element from a stream input? I tried parsing such an XML but got a org.xml.sax.SAXParseException: The markup in the document following the root element must be well-formed. before even the endDocument event was fired. I would like not to settle with obvious but clumsy solutions as "Pre-append a custom root element or Use buffered fragment parsing". I am using the standard SAX API of Java 1.6. The SAX
