◆ QQmlXmlListModel()

QQmlXmlListModel::QQmlXmlListModel ( QObject * parent = nullptr )

\qmltype XmlListModel \inqmlmodule QtQml.XmlListModel

For specifying a read-only model using XML data.

To use this element, you will need to import the module with the following line:

import QtQml.XmlListModel

XmlListModel is used to create a read-only model from XML data. It can be used as a data source for view elements (such as ListView, PathView, GridView) and other elements that interact with model data (such as Repeater).

Note: This model {does not} support the XPath queries. It supports simple slash-separated paths and, optionally, one attribute for each element.

For example, if there is an XML document at https://www.qt.io/blog/rss.xml like this:

<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0">
  ...
  <channel>
    <item>
      <title>Qt 6.0.2 Released</title>

    <item>
      <title>Qt Creator 4.14.1 released</title>
      <link>https://www.qt.io/blog/qt-creator-4.14.1-released</link>
      <pubDate>Wed, 24 Feb 2021 13:53:21 GMT</pubDate>
    </item>
  </channel>
</rss>

A XmlListModel could create a model from this data, like this:

\qml import QtQml.XmlListModel

XmlListModel { id: xmlModel source: "https://www.qt.io/blog/rss.xml" query: "/rss/channel/item"

XmlListModelRole { name: "title"; elementName: "title" } XmlListModelRole { name: "pubDate"; elementName: "pubDate" } XmlListModelRole { name: "link"; elementName: "link" } } \endqml

The \l {XmlListModel::query}{query} value of "/rss/channel/item" specifies that the XmlListModel should generate a model item for each { } in the XML document.

The \l [QML] {XmlListModelRole} objects define the model item attributes. Here, each model item will have title, pubDate and link attributes that match the title, pubDate and link values of its corresponding { }. (See \l [QML] {XmlListModelRole} documentation for more examples.)

The model could be used in a ListView, like this:

\qml ListView { width: 180; height: 300 model: xmlModel delegate: Text { text: title + ": " + pubDate + "; link: " + link } } \endqml

The \l XmlListModel data is loaded asynchronously, and \l status is set to XmlListModel.Ready when loading is complete. Note this means when \l XmlListModel is used for a view, the view is not populated until the model is loaded.

Note that when the progress is 1.0, the XML data has been downloaded, but it is yet to be loaded into the model at this point. Use the status property to find out when the XML data has been read and loaded into the model.

◆ rowCount()

int QQmlXmlListModel::rowCount ( const QModelIndex & parent ) const

overridevirtual

Returns the number of rows under the given parent.

When the parent is valid it means that rowCount is returning the number of children of parent.

Note: When implementing a table based model, rowCount() should return 0 when the parent is valid.
