QDomImplementation real dom Document;

Printable View

i wand to write xml doc on QDomDocument not entyti ....

on line to line the doc is so:

Code:

QStringList xml;
    xml.append("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
    xml.append("<cms:root xmlns:cms=\"http://www.pulitzer.ch/2005/PuliCMS/1.0\">");
    xml.append("<cms:page la=\"it\">");
    xml.append(desc_it->GetXMLTag());
    xml.append("</cms:page>");
    xml.append("</cms:root>");
    QString stayutf8 = xml.join("\n");
   qDebug() << "### xml result1   "  << stayutf8;

and on a real QDomDocument.... Manual say so:

Code:

QDomDocument doc(QDomImplementation::createDocument(QString("http://www.pulitzer.ch/2005/PuliCMS/1.0/"),
                 QString("utf8"),(const QDomDocumentType)"xml"));
    QDomElement root = doc.createElement("root");
    root.setAttribute("xmlns:s","http://www.pulitzer.ch/2005/shop/shema/1.0/");
    root.setAttribute("xmlns:cms","http://www.pulitzer.ch/2005/PuliCMS/1.0/");
    doc.appendChild(root); 
    QDomElement page = doc.createElement("cms:page");
    page.setAttribute("xmlns:cms","http://www.pulitzer.ch/2005/PuliCMS/1.0/");
    page.setAttribute("la","it");
    page.appendChild((const QDomDocumentFragment)(desc_it->GetXMLTag()));
    root.appendChild(page);
    QString xml = doc.toString();
    qDebug() << "### xml result2   "  << xml;

on php5 and qt all dom function is same but new domdocument no....

php = $dom = new DOMDocument('1.0', 'utf-8') and become a clean first line...

qt no why?

how to become a clean line <?xml version=\"1.0\" encoding=\"utf-8\"?> so tidy xml dont clean?

Because DOM Level 2 specification does not specify the constructor of Document (since it's an interface, not a class).

As usual in Qt --- with only a few lines of code:
Code:

#include <QDomDocument> #include <QtDebug> int main() { QDomDocument doc; QDomProcessingInstruction header = doc.createProcessingInstruction( "xml", "version=\"1.0\"" ); doc.appendChild( header ); QDomElement root = doc.createElement( "test" ); doc.appendChild( root ); qDebug() << doc.toString(); return 0; }
Quote:

$ ./xml
"<?xml version="1.0"?>
<test/>
"

Re: QDomImplementation real dom Document;

and QDomDocumentFragment so helpfull is the same?

Code:

QDomElement page = doc.createElement("cms:page");
page.setAttribute("xmlns:cms","http://www.pulitzer.ch/2005/PuliCMS/1.0/");
page.setAttribute("la","it");
page.appendChild((const QDomDocumentFragment)(desc_it->GetXMLTag()));
root.appendChild(page);

I'm not sure what you mean.

What does GetXMLTag() return? It seems that you are doing something dangerous here.

Fragments of xml return.... tree or only </nocode>
I wand to attach piece of fragment to other... to build on file...

If that method returns QDomDocumentFragment, then why do you need a cast?

why? is a existing file ... trasformed to qstring and replace <? xml...>

wenn i open the file on QDomDocument ... on error.... i must return a empyty dom?
on qstring on error read i return a <nullnode/> qstring...
qt code

Code:

if(!xmlfile.open( QIODevice::ReadOnly ) ) {
    out....
    }
    QString errorStr;
    int errorLine;
    int errorColumn;
 
    QDomDocument doc("http://www.pulitzer.ch/2005/PuliCMS/1.0");
     if (!doc.setContent(&xmlfile,true, &errorStr, &errorLine, &errorColumn)) {
         QString error = (QString("Parse error at line %1, column %2:\n%3")
         .arg(errorLine)
         .arg(errorColumn)
         .arg(errorStr) );
        ErrorConfig(error);
     xmlfile.close();
     }

the best way i think to make a similar php class on qt...

php code

Code:

/*  Aggregate moore xml file to one or insert xml fragment */
 
class XML extends DOMDocument {
    function __construct () {
	parent::__construct ();
	}
	function __destruct() {
    parent::__destruct();
    }
	/*  function similar from createDocumentFragment but enter xml file or pure xml frags */ 
	function appendXML_or_File($node,$frag) {
 
	if (is_file($frag)) {
	$frag = @file_get_contents($frag);
	} 
	$tmpdoc = new self('1.0', 'utf-8');
	$tmpdoc->loadXML("<dummyroot>".$this->Remove_Version($frag)."</dummyroot>") 
		or Error_Manager::msg('Error on fragment not possibel to insert xml Fragment!'.htmlentities($frag, ENT_QUOTES),__FILE__,__LINE__);
    $newnode = $node->ownerDocument->importNode($tmpdoc->documentElement,true);
    $child = $newnode->firstChild;
    while ($child) {
        $nextChild = $child->nextSibling;
        $node->appendChild($child);
        $child = $nextChild;
    }
    }
	/*  remove php code or xml header ..... */
    function Remove_Version($string) {
    return preg_replace_callback("/(<\?php|<\?)(.*?)\?>/si",create_function("","return '';"),$string);
    }
	function utf($string) {
	return Multi_Language::utf8_to_unicode($string);
	}
 
}

but can i open qtextstreams on dom?

Code:

if (! doc.setContent(qtextstreams...) ) {

I was asking about this:

Quote:

(const QDomDocumentFragment)(desc_it->GetXMLTag())

Either you don't need it or you do something Bad.

Not directly, but you can try:
Code:

doc.setContent( stream.readAll() );

Re: QDomDocumentFragment is not !isDocumentFragment()

The fragment is not fragment!

Qtextstream "<samplenode/>" readAll() return a false QDomDocument

and fragment give a false isDocumentFragment() why?

Code:

#include <QtDebug>
#include <QDebug> 
#include <QObject>
#include <QSettings>
#include <QErrorMessage>
#include <QProcess>
#include <QDomDocument>
#include <QDomElement>
#include <QStringList>
#include <QDir>
#include <QDomDocumentFragment>
#include <QDomImplementation>
#include <QMessageBox>
 
int main(int argc, char *argv[]) {
 
    QDomDocument dom_external; 
    QString filexmleternal = "./qtpage.xml";
    bool is_fi = false;
 
    QFile xmlfile(filexmleternal);
    if(!xmlfile.open( QIODevice::ReadOnly ) ) {
     /* stay false ! */
    }
    if (dom_external.setContent(&xmlfile)) { 
    is_fi = true;
    }
    if (!is_fi) {
      qDebug() << "External file not loadet!";   
    } else {
      qDebug() << "External file is super!! loadet!";  
      QDomDocumentFragment frag;
      frag.appendChild(dom_external);
       if (!frag.isDocumentFragment()) {
        qDebug() << "Is not a fragment !!!"; 
       }           
    }
 
   /* external file end */
  /* new qdom to insert external ... */
   QDomDocument doc;
   QDomProcessingInstruction header = doc.createProcessingInstruction( "xml", "version=\"1.0\"" );
   doc.appendChild( header );
   QDomElement root = doc.createElement( "root" );
   doc.appendChild( root );
    QDomElement big = doc.createElement( "big" );
    if (is_fi) {
    //////big.appendChild(frag);   /* not insert */
    }
    root.appendChild( big );
    /////QDomNode::isDocumentFragment ()
   qDebug() << doc.toString();
   return 0;
};

pro file...

Code:

TEMPLATE = app console
TARGET += 
DEPENDPATH += .
INCLUDEPATH += .
 
win32:debug { CONFIG = console } 
CONFIG  += qt warn_on release
QT += xml
 
# Input
SOURCES += main.cpp

Probably it's a bug, use QDomDocument::createDocumentFragment() to create document fragments.

PS. If you post code, please, post only relevant part. 3/4 of your example has nothing to do with QDomDocumentFragment.

Re: QDomImplementation real dom Document;

is solved so.... and fragment not run!

make a node from external root and .toElement(); after big.appendChild(extase);
to other node....

Code:

int main(int argc, char *argv[]) {
 
    QDomDocument dom_external; 
    QString filexmleternal = "./qtpage.xml";
    bool is_fi = false;
 
    QFile xmlfile(filexmleternal);
    if(!xmlfile.open( QIODevice::ReadOnly ) ) {
     /* stay false ! */
    }
    is_fi = dom_external.setContent(&xmlfile);  
    QDomElement root_extern = dom_external.documentElement(); 
    QDomNode externxml = root_extern.firstChild();
    QDomNode externxml_2 = dom_external.importNode(externxml,true);
    QDomElement extase = externxml_2.toElement(); 
 
    if (!is_fi) {
      qDebug() << "External file not loadet!";   
    } else {
      qDebug() << "External file is super!! loadet!";           
    }
 
   QDomDocument doc;
   QDomProcessingInstruction header = doc.createProcessingInstruction( "xml", "version=\"1.0\"" );
   doc.appendChild( header );
   QDomElement root = doc.createElement( "root" );
   doc.appendChild( root );
   QDomElement big = doc.createElement( "big" );
   big.appendChild(extase);  /* the external file not from fragment */
   root.appendChild( big );
 
 
 
   qDebug() << doc.toString();
   return 0;
};

Thanks, this helps me!
