Access elements of the xml-file

[8Observer8]

Hi, everyone!

I read the xml-file:

<Matrix> 
<Description> 
        <rows>3</rows> 
        <columns>4</columns> 
</Description> 
<row1> 
        <cell>23.7</cell> 
        <cell>2.7</cell> 
        <cell>3.7</cell> 
        <cell>23.9</cell>       
</row1> 
<row2> 
        <cell>13.0</cell> 
        <cell>2.7</cell> 
        <cell>3.7</cell> 
        <cell>2</cell>  
</row2> 
<row3> 
        <cell>2.5</cell> 
        <cell>2.7</cell> 
        <cell>3.7</cell> 
        <cell>23.9</cell>       
</row3> 
</Matrix>

<Matrix> 
<Description> 
        <rows>3</rows> 
        <columns>4</columns> 
</Description> 
<row1> 
        <cell>23.7</cell> 
        <cell>2.7</cell> 
        <cell>3.7</cell> 
        <cell>23.9</cell>       
</row1> 
<row2> 
        <cell>13.0</cell> 
        <cell>2.7</cell> 
        <cell>3.7</cell> 
        <cell>2</cell>  
</row2> 
<row3> 
        <cell>2.5</cell> 
        <cell>2.7</cell> 
        <cell>3.7</cell> 
        <cell>23.9</cell>       
</row3> 
</Matrix>

To copy to clipboard, switch view to plain text mode 

I want to write to the console these names of tags 'row1' and 'row2':

qDebug() << rowElement1.tagName();
qDebug() << rowElement2.tagName();

qDebug() << rowElement1.tagName();
qDebug() << rowElement2.tagName();

I expect to see:

"row1"
"row2"

But I see:

"row1"
"row1"

QDomElement rowElement2 = rowElement1.nextSiblingElement();
qDebug() << rowElement2.tagName();

QDomElement rowElement2 = rowElement1.nextSiblingElement();
qDebug() << rowElement2.tagName();
