Bug 31099 – [Qt] Add a way to access text nodes tree with QWebElement

• Component: WebKit Qt
• Status: RESOLVED INVALID

[Benjamin Poulain]

There is no way to access text nodes children of QWebElement. This limit the use of the API. Here is an example

How do I get "prefix" and "suffix" with QWebElement in the following snippet:
"<div>
  prefix
  <img src=""/>
  suffix
</div>"


To solve this, we could introduce a new class to iterate over the content of the QWebElement (QWebElementIterator || QWebElementCusor).

E.g.:

QWebElementCursor cursor(element);
while (cursor.next()) {
    if (cursor.isText()) {
        cursor.setHtml(QString("<p>%1</p>").arg(cursor.text()));
        //? int selectionOffset = cursor.textSelectionBeginning();
    } else if (cursor.isElement()) {
        QWebElement child = cursor.element();
        child.encloseWith("<div>");
    }
}

4.7 stuff definately. I have also had requests for iterating the text itself, and querying for size, position etc.

This is useful for ebook readers etc that want to split text blocks to fit as much contents on a page as possible, and put all overflow to the next page.

There are probably more usecases for this.

Maybe it should be not blocking 2.1 API metabug(?)

Meanwhile, has anyone found any workaround?

I think this is pretty much dead after the switch of focus to WebKit2. I don't know what API will replace QWebElement (if any).

I think the only way to workaround this is to use JavaScript to modify the DOM.
