[Qt-interest] QXmlSreamReader

[Sebastian Schöbinger]

hi

thank you for your answer (I couldn't write back earlier, because I had
no Computer :( )
It works good, but my xml file looks like this:

<title lang="en">German-English Dictionary"</title>

and the program just shows me

title

langen
, but I also want to see "German-English Dictionary"


how is that "codeable" ? ;)
