[solved] QtWebKit - how to find name of radio button

guziemic

Hi,

I have web page on which there are radio buttons in form. Relevant part of page:
@
<form>
...
<tr>
<td colspan="2" class="input">
<input class="noborder" name="radiobuttonMH" value="radio2" type="radio"> Radio button 2
</td>
</tr>
...
</form>
@

My aim is to provide to user all possible choices when he click on one of radio buttons. I am able to find a group of radio buttons within <form> with the same name. But I have problems with values. As you can see on snippet of page value of button is "radio2" and the text visible for user on web page is "Radio button 2". I would like to present on some dialogue window to the user the name visible on web page and not the value. Which can be very different from visible text.

I already tried some options that QWebElement provide to get this real name but without success.
Code that I checked:
@
qDebug() << "Element " << i << "\nTag" << radioCollection.at(i).tagName()
<< "\nName" << radioCollection.at(i).attribute("name")
<< "\nPlain" << radioCollection.at(i).toPlainText()
<< "\nLocal name" << radioCollection.at(i).localName()
<< "\nPrefix" << radioCollection.at(i).prefix()
<< "\nInnerXml" << radioCollection.at(i).toInnerXml()
<< "\nOuterXml" << radioCollection.at(i).toOuterXml()
<< "\nAttributes" << radioCollection.at(i).attributeNames()
<< "\nNamespaceUri" << radioCollection.at(i).namespaceUri();
@

Output:
@
Element 1
Tag "INPUT"
Name "radiobuttonMH"
Plain ""
Local name "input"
Prefix ""
InnerXml ""
OuterXml "<input class="noborder" name="radiobuttonMH" value="radio2" type="radio">"
Attributes ("class", "onfocus", "onblur", "name", "value", "type")
NamespaceUri "http://www.w3.org/1999/xhtml"

Thanks for answers.

I don't understand 100%, but the "Radio button 2" is not part of radio button but its a value of a particular cell of the table.

Probably from HTML point of view you are right, but the radio buttons can also be outside table like here
@
<form>
...
<input class="noborder" name="radiobuttonMH" value="radio2" type="radio"> Radio button 2
...
</form>

@

Then I will be not able to get value of table cell. Thus, I am looking for some general solution.

And if some one will have such form then I will not have choice and I plan to send value of radio to user. But on web page user will see only circle.

@
<form>
...
<input class="noborder" name="radiobuttonMH" value="radio2" type="radio">
...
</form>

Because the web page is not correct. A label tag is need for a radio button for a 'text information'.
In this case i don't know a good solution. Maybe only an hard parser.

Yes, with <label> it is different story. I was not aware about this tag in HTML. Well, I will need to deepen knowledge about HTML. Unfortunately for me, I notice that some of web developers do not use <label> and just write raw text after definition of <input type=radio>.

Even on most HTML tutorials they do not mention about that tag. For instance "HTML tutorial":http://www.htmlcodetutorial.com/forms/_INPUT_TYPE_RADIO.html

Thanks.

I also implemented hard parser in following way. But I think it is time consuming operation, as there is a lot of operation related to QString.

@
a_oWebElement - input element
QString CClass::getWebElementInnerText(QWebElement & a_oWebElement)
{
QString strRetVal;

//find text visible on WebPage (need to be stripped from any white space characters
QString text = a_oWebElement.toOuterXml();

//  qDebug() << text;
QString strHtml = a_oWebElement.webFrame()->toHtml();
int position = strHtml.indexOf(text, Qt::CaseInsensitive);
int tagPosition = strHtml.indexOf("<", (position + text.size()), Qt::CaseInsensitive);

for (int j = (position + text.size()); j < tagPosition; ++j)
    strRetVal.append(strHtml.at(j));


strRetVal = strRetVal.trimmed();

// qDebug() << "innerText - " << innerText << "position" << position << "tagPosition" << tagPosition;

return strRetVal;

}
