Mysterious QXMLStreamReader parsing behavior

[ym1206]

Hi,all,

I am new to Qt xml classes.
When reading XmlStreamReader example from the book by Jasmin Blanchette, I encountered mysterious QXMLStreamReader parsing behavior.
The small xml file from the book is listed as following:

<?xml version="1.0"?>
<bookindex>
<entry term="sidebearings">
<page>10</page>
<page>34-35</page>
<page>307-308</page>
</entry>
<entry term="subtraction">
<entry term="of pictures">
<page>115</page>
<page>244</page>
</entry>
<entry term="of vectors">
<page>9</page>
</entry>
</entry>
</bookindex>
My question is: Why do so many "Characters" Tokens emerge during the parsing procedure?
As an example, for line "<page>307-308</page>", after readElementText(),Token is "EndElement", with another readNext(), "</entry>" should be read, and the token is supposed to be "EndElement", but "Characters" token appeared, Why?

Thanks for your help.


All the tokens reported by the parser are listed below:
StartDocument
StartElement
Characters
StartElement
Characters
StartElement
EndElement

Characters
EndElement

EndElement
Characters
EndElement
Characters

EndDocument

Hello Friend,

I can't say exactly, but it might be a whitespace, i think the parser consider whitespace as "Characters".
so just check for whitespace before you read next element...

try this to check whitespace..!!


QXmlStreamReader *reader = new QXmlStreamReader();
if( reader->isWhitespace() == true )
{
reader->readNext();
}

Thanks for your help.

I'll try to understand the example code with WhiteSpace and NewLine in mind.:D
