QDomProcessingInstruction(3qt)

📦 version 3.3.8b, in fedora 43, fedora 44

💖 QDomProcessingInstruction — the manual page, but make it make sense 💖

okay bestie, so this is the man page for QDomProcessingInstruction from the 3qt manual, and yes we are about to make an XML processing instruction sound cute. it's giving "niche but iconic". let's go ✨

🌸 NAME 🌸

QDomProcessingInstruction — literally just a class that represents an XML processing instruction. that's the whole gig. 💅

✨ SYNOPSIS ✨

okay so first things first, and this is important so don't skip it:

All the functions in this class are reentrant when Qt is built with thread support.</p>

(yeah that stray </p> is in the original, we don't ask questions, we just respect the lore 🙈)

and you get to it like this:

#include <qdom.h>

Inherits QDomNode. so it's a node, it's just a special node. main character energy, obviously 👑

💜 DESCRIPTION 💜

so QDomProcessingInstruction represents an XML processing instruction. that's it, that's the class. 🎀

processing instructions are the little guys XML uses to keep processor-specific information sitting right there in the text of the document. iykyk.

you pull the content of the processing instruction out with data(), and you set it with setData(). you get the processing instruction's target with target(). simple. clean. slay.

if you want to go deeper on the Document Object Model (and honestly, respect), hit up http://www.w3.org/TR/REC-DOM-Level-1/ and http://www.w3.org/TR/DOM-Level-2-Core/. and for a more general intro to the DOM implementation, go read the QDomDocument documentation. 🦋

See also XML.

🧚 MEMBER FUNCTION DOCUMENTATION 🧚

QDomProcessingInstruction::QDomProcessingInstruction ()

constructs an empty processing instruction. if you want one with actual content in it, use QDomDocument::createProcessingInstruction(). don't come crying to the default constructor, it literally has nothing to give you 😭

QDomProcessingInstruction::QDomProcessingInstruction ( const QDomProcessingInstruction & x )

constructs a copy of x. 📋

heads up bestie: the data of the copy is shared (shallow copy), which means modifying one node will also change the other. if you want a deep copy, use cloneNode().

QDomProcessingInstruction::~QDomProcessingInstruction ()

destroys the object and frees its resources. RIP to a real one 💀✨

QString QDomProcessingInstruction::data () const [virtual]

returns the content of this processing instruction. that's the good stuff right there.

See also setData() and target().

bool QDomProcessingInstruction::isProcessingInstruction () const [virtual]

returns TRUE. yes. always. it's literally a processing instruction, babe. 💅

Reimplemented from QDomNode.

QDomNode::NodeType QDomProcessingInstruction::nodeType () const [virtual]

returns ProcessingInstructionNode. shocker, i know. 🎀

Reimplemented from QDomNode.

QDomProcessingInstruction & QDomProcessingInstruction::operator= ( const QDomProcessingInstruction & x )

assigns x to this processing instruction.

same warning as before: the data of the copy is shared (shallow copy), so modifying one node will also change the other. want a deep copy? cloneNode(). that's the move.

void QDomProcessingInstruction::setData ( const QString & d ) [virtual]

sets the data contained in the processing instruction to d. you're the one in charge now 👑

See also data().

QString QDomProcessingInstruction::target () const [virtual]

returns the target of this processing instruction. 🎯

See also data().

💀 BUGS 💀

if you find a bug in Qt, please report it as described at http://doc.trolltech.com/bughowto.html. good bug reports help us to help you. thank you. 🫶 (fr fr, be a good bug reporter, it's a public service)

the definitive Qt documentation is provided in HTML format. it lives at $QTDIR/doc/html and you can read it using Qt Assistant or with a web browser. this man page is provided as a convenience for those users who prefer man pages, although this format is not officially supported by Trolltech. so like, it's a vibe, not a contract. 💅

if you find errors in this manual page, please report them to qt-bugs@trolltech.com. please include the name of the manual page (qdomprocessinginstruction.3qt) and the Qt version (3.3.8). don't be vague, bestie, give them the deets 🙈

and that's the whole page!! mwah 💖 brought to you by Trolltech AS, dated 2 February 2007, from the Qt 3.3.8 era of the QDomProcessingInstruction(3qt) manual. she's vintage, she's reentrant, she's everything. periodt. 🎀🦋⭐
