QDomElement's text() for <element> </element> giving me a empty Qstring

[CirqueForge]

Here's a simple example that hopefully will help :

#include <QDomDocument>
#include <QXmlSimpleReader>
#include <QDebug>
 
int main(){
 
    QString xmlString("<original> </original>");
    QXmlInputSource source;
    source.setData(xmlString);
    QXmlSimpleReader reader;
    QDomDocument doc;
    doc.setContent(&source, &reader);
    QDomElement docElem = doc.documentElement();
    qDebug() << docElem.tagName() << docElem.text();
}

#include <QDomDocument>
#include <QXmlSimpleReader>
#include <QDebug>

int main(){

    QString xmlString("<original> </original>");
    QXmlInputSource source;
    source.setData(xmlString);
    QXmlSimpleReader reader;
    QDomDocument doc;
    doc.setContent(&source, &reader);
    QDomElement docElem = doc.documentElement();
    qDebug() << docElem.tagName() << docElem.text();
}

Outputs: "original" " "

Kinda helpful for me to understand what QXmlSimpleReader does but I think you are misunderstanding me.

The thing is from "<original>　</original>", I want to get a Qstring with " ". As in, I want to read the whitespace and nothing else. I want it so that not only when I parse "<original>　</original>" do I get a whitespace but for some control tags, "<control>　 </control>", the Qstring would give me " ". Is there a way from any classes in Qt or any kind of manual implementation I can use to read a node so it will do that for me? Or is there some way I can bypass this non-whitespace reading?

Edit: Even the forum doesn't seem to respect whitespace handling, haha... I meant for <control></control> to have 6 spaces in between.

As in, I want to read the whitespace and nothing else.

QDomElement::text() will return a QString that will contain 6 spaces if your element contains 6 spaces.

QDomElement::text() will return a QString that will contain 6 spaces if your element contains 6 spaces.

It doesn't if the node is just whitespace. It will just return an empty Qstring. That's the entire problem and hence, why I'm asking if there's another way to get text from the element using either other classes or doing it manually.

Edit: Do you mean to say that when I read it using a QXMLSimpleReader, QDomElement::text() will return the whitespace nodes correctly?

Bingo.

Modified simple program:

#include <QDomDocument>
#include <QXmlSimpleReader>
#include <QDebug>
 
int main(){
    QString xmlString("<original>      </original>");
    QDomDocument doc;
    doc.setContent(xmlString);
    QDomElement docElem = doc.documentElement();
    qDebug() << "Without QXmlSimpleReader \t- element contains" <<docElem.text() << "\tlength="<< docElem.text().length();
    doc.clear();
    QXmlInputSource source;
    source.setData(xmlString);
    QXmlSimpleReader reader;
    doc.setContent(&source, &reader);
    docElem = doc.documentElement();
    qDebug() << "With QXmlSimpleReader \t- element contains" <<docElem.text() << "\tlength="<< docElem.text().length();
}
 
//Output:
//Without QXmlSimpleReader 	- element contains "" 	        length= 0 
//With QXmlSimpleReader 	- element contains "      " 	length= 6

#include <QDomDocument>
#include <QXmlSimpleReader>
#include <QDebug>

int main(){
    QString xmlString("<original>      </original>");
    QDomDocument doc;
    doc.setContent(xmlString);
    QDomElement docElem = doc.documentElement();
    qDebug() << "Without QXmlSimpleReader \t- element contains" <<docElem.text() << "\tlength="<< docElem.text().length();
    doc.clear();
    QXmlInputSource source;
    source.setData(xmlString);
    QXmlSimpleReader reader;
    doc.setContent(&source, &reader);
    docElem = doc.documentElement();
    qDebug() << "With QXmlSimpleReader \t- element contains" <<docElem.text() << "\tlength="<< docElem.text().length();

Yeah, I was able to get it to work correctly after doing so. Thank you for your help.

It's not the forum, it's your web browser.
