HI
I'm going to develop a tourist app, that shows cards in a webview. At first I planned to have variuos html files, next I decided to have a single file html, and each page/card /denoted by a <section> marker.
I edited the file and transformed it in xhmlt, in order to parse it looking for a section with a certaing name (the idea is taken from cmsimple, a cms that works very well without database and use the <h1> tag as marker for each page.) Then I created that simple piece of code, but realized that the text returned is the last chunk of text enclodes in a set of tag <..> </..>
I thought that the EndElement event for section would be the whole html enclosed inside it.
Is it a correct behaviour? Is there a way to parse a file and to retrieve the text enclosed in side <section name="akey">...</section>?
thanks in advance
alex
the example uses 3 buttons, each looking for a particular section.
this is the xml file
consider that looking for key "ob3.html" my code returns cccc and not
<h1>
Alessandro Manzoni
</h1>
<p align="justify">
cccc
</p>
as I expected
So. I ask if there is way to extraxt a chunk of text using a keyword from a single file containg mode parts corresponding each to an html page.
thanks
