Data Parsers


I want to get some data from a website for my app, what I have right now is getting the HTML source for the site, and storing it in a QString. Then parsing the QString which gets the specific values I need from the webpage.


Problem is, when parsing I'm using things like QString.split, indexOf(), etc, and for this I need multiple nested loops. This causes the program to run really slow (with 3 nested loops).


Does anyone have another way of doing this without using String manipulations, to get specific data from a website. Thanks

Re: Data Parsers

Does this website have an api that you could use to get pure xml or json? There is not an easy way to parse html, but you could try to run it through XMLDataAccess and see if it parses it.

Re: Data Parsers

If there is no other way to access the data you want, using regular expressions would possibly be a better choice.
Have a look at the QRegExp class.
