Qt parse html file

The text representation of JSON encloses arrays in square brackets [ Entries in arrays and objects are separated by commas.

The separator between keys and values in an object is a colon :. Two of the values are strings, one is a number, one is another object and the last one an array. A valid JSON document is either an array or an object, so a document always starts with a square or curly bracket.

Is it a good parser? I'm aware of it because it is a spin of of a project I use, Cutelyst, a web framework. I use HTML as output, via grantlee templates, not as input or woring format.

Konstantin-Tokarev Thank you. I only want to download a HTML source or load it from a file, and then parse it. For implementated XML parsers with Qt, are they also good as libxml2 or gumbo-parser? Meanwhile for your answer, I will give an other try for libxml2 and gumbo-parser.

Don't underestimate value of "CSS queries" point - in case you have complex documents where you need to process only a few deeply nested elements, it can be very handy to have full-blown CSS query engine.

You may like API of Qt parsers more, but speed may be worse than with others. QDom has abysmal performance, QXmlStreamReader is much faster but still has no way around conversion of all document text to UTF16 internally which hurts performance if your document is e. I agree with about QtWebKit. But, what about the performances? It does not keep the content read earlier in memory, thus is appropriate for handling large xml file.

The speed is also superior to QDomDocument. Then, the first thing is to get the root element of the xml document using QDomDocument::documentElement. The root element,i. It is not the root element of xml document; it is even not a part of xml document. The most often used function is QDomElement::text, which obtains the text between the open tag and close tag.
