Hello All experts this is my code to create the xml file.

I want result in following format
<ui name="UI EDITOR" >
<ribbon>
<tab/>
<panel>
<button/>
<button/>
</panel>
</ribbon>
</ui>

But i am getting result in this format
<ui name="UI EDITOR" >
<ribbon>
<tab/>
<panel>
<button/>
</panel>
</ribbon>
</ui>
<ui name="UI EDITOR" >
<ribbon>
<tab/>
<panel>
<button/>
<button/>
</panel>
</ribbon>
</ui>

Please tell me where i am commiting mistake

I WANT TO INSERT THE button NODE DYNAMICALLY

why you can't just append a child?

[vajindarladdad]

panel.appendChild(newButton); //appending to the panel node

Sir , i am appending a child .. but not getting the desired output, repetation of ui , ribbon tab...etc does occure

[vajindarladdad]

In what other way i can do the same

[spirit]

as I understand you need to add data between these tags


<ui name="UI EDITOR" >
<ribbon>
....
</ribbon>
<ui name="UI EDITOR" >

right?

why you can't create a method wich will generate whole xml at all?

[vajindarladdad]

Sir if you could provide me an example code to do so ..
I would be very grateful.

[vajindarladdad]

Thanks ... here is a code to do so......

[CODE ]
void Ribbon::WriteXml(int id ,QString location)
{
QFile file("xml/node.xml");

if(id==1)
{
QDomElement uiElementNode , documentElement , ribbonElementNode , tabElementNode , panelElementNode , buttonElementNode;
if(!file.open(QIODevice::ReadWrite | QIODevice::Text))
{
qDebug("Error... in opening a file");
return ;
}

uiElementNode = document.createElement("ui");
uiElementNode.setAttribute("name", "UI EDITOR");
document.appendChild(uiElementNode);

ribbonElementNode = document.createElement("ribbon");
uiElementNode.appendChild(ribbonElementNode);

tabElementNode = document.createElement("tab");
ribbonElementNode.appendChild(tabElementNode);

panelElementNode = document.createElement("panel");
tabElementNode.appendChild(panelElementNode);

buttonElementNode = document.createElement("button");
buttonElementNode.setAttribute("id",QString::number(id));
buttonElementNode.setAttribute("tooltip",location);
panelElementNode.appendChild(buttonElementNode);

QTextStream out(&file);
out << document.toString(); //writting to a file
file.close();

}
else // here we need to insert button node to the panel
{
if(!file.open(QIODevice::ReadWrite | QIODevice::Text))
