[solved] XmlListModel problem
-
Hi,
I can't get this model to work:
@XmlListModel {
id: xmlModel
source: "http://gdata.youtube.com/schemas/2007/categories.cat"
query: "/app:categories/atom:category"namespaceDeclarations: "declare default element namespace 'http://www.w3.org/2005/Atom'; \ declare namespace yt='http://gdata.youtube.com/schemas/2007';" XmlRole { name: "term"; query: "yt:@term/string()" } XmlRole { name: "label"; query: "yt:@label/string()" }
}@
the xml contains:
@<?xml version='1.0' encoding='utf-8'?>
<app:categories xmlns:app='http://www.w3.org/2007/app'
xmlns:atom='http://www.w3.org/2005/Atom'
xmlns:yt='http://gdata.youtube.com/schemas/2007' fixed='yes'
scheme='http://gdata.youtube.com/schemas/2007/categories.cat'>
<atom:category term='Film' label='Film & Animation' xml:lang='en-US'>
<yt:assignable />
<yt:browsable regions='AR ... ZA' />
</atom:category>
[...]@I don't understand what I have to do. Any suggestions ?
thanks a lot

Hi, deimos,
after the definition of the XmlListModel based on the XMLS file, did you created also the other components? Do you to show this file in a list ?
It should be defined the delegate and the list...

Hi Alicemirror,
thanks for the reply.
I tried to learn XQuery all the night, but just for luck I got what I wanted ;)
Yes I use the XmlListModel as a model in a GridView. Here the working code:@Rectangle {
id: categoryButtonsXmlListModel { id: xmlModel source: "http://gdata.youtube.com/schemas/2007/categories.cat" query: "/categories/atom:category" namespaceDeclarations: "declare default element namespace 'http://www.w3.org/2007/app';"+ "declare namespace atom='http://www.w3.org/2005/Atom';"+ "declare namespace yt='http://gdata.youtube.com/schemas/2007';" XmlRole { name: "term"; query: "@term/string()" } XmlRole { name: "label"; query: "@label/string()" } } GridView { id: buttonsGridView model: xmlModel delegate: MDcomboButton { width: 100 height: 50 text: label+" - "+term } cellWidth: parent.width/8 cellHeight: cellWidth/2 width: parent.width height: parent.height }
}@
but I still don't understand the query statement: why it has not the "app:" beside "categories" ? I should learn more about these :)
thanks again

Hi Deimos,
bq. but I still don’t understand the query statement: why it has not the “app:” beside “categories” ? I should learn more about these :)
What does it means ? I tried to understand it without results :)

AAaaaahhhhhh :-(
Sorry, now I see. It is in your xml.
Well, if it can help you, everytime I see a new "dialect" of the xml I became crazy to understand what it means.
I think that this is a useful link to understand exactly what does means your xml file: http://www.w3.org/standards/xml/
Advice: keep it in your bookmarks :)

Yep. It maybe a good idea to post a wiki page with a simplified but useful version of the most frequent cases of how the xml can be expressed...
