/**
|
|
|
|
Implements the interface to the "Visitor pattern" (see the Accept() method.)
|
|
|
|
If you call the Accept() method, it requires being passed a XMLVisitor
|
|
|
|
class to handle callbacks. For nodes that contain other nodes (Document, Element)
|
2012-05-12 12:21:23 +00:00
|
|
|
you will get called with a VisitEnter/VisitExit pair. Nodes that are always leafs
|
2012-02-10 02:16:58 +00:00
|
|
|
are simply called with Visit().
|
|
|
|
|
|
|
|
If you return 'true' from a Visit method, recursive parsing will continue. If you return
|
2012-05-12 12:21:23 +00:00
|
|
|
false, <b>no children of this node or its sibilings</b> will be visited.
|
2012-02-10 02:16:58 +00:00
|
|
|
|
|
|
|
All flavors of Visit methods have a default implementation that returns 'true' (continue
|
|
|
|
visiting). You need to only override methods that are interesting to you.
|
|
|
|
|
2012-05-12 12:21:23 +00:00
|
|
|
Generally Accept() is called on the TiXmlDocument, although all nodes support visiting.
|
2012-02-10 02:16:58 +00:00
|
|
|
|
|
|
|
You should never change the document from a callback.

XML tree will be conditionally visited and the host will be called back
|

via the TiXmlVisitor interface.
|
|
|
|
|
|
|
|
This is essentially a SAX interface for TinyXML. (Note however it doesn't re-parse
|
|
|
|
the XML for the callbacks, so the performance of TinyXML is unchanged by using this
|
|
|
|
interface versus any other.)
|
|
|
|
|
|
|
|
The interface has been based on ideas from:
|
|
|
|
|
|
|
|
- http://www.saxproject.org/
|
|
|
|
- http://c2.com/cgi/wiki?HierarchicalVisitorPattern
|
|
|
|
|
|
|
|
Which are both good references for "visiting".
|
|
|
|
|
|
|
|
An example of using Accept():
|
|
|
|
@verbatim
|
|
|
|
TiXmlPrinter printer;
|
|
|
|
tinyxmlDoc.Accept( &printer );
|
|

const char* xmlcstr = printer.CStr();

|

A text node can have 2 ways to output the next. "normal" output

|

and CDATA. It will default to the mode it was parsed from the XML file and
|
|
|
|
you generally want to leave it alone, but you can change the output mode with
|
|
|
|
SetCDATA() and query it with CDATA().

/** Convenience function for easy access to the text inside an element. Although easy
|
|
|
|
and concise, GetText() is limited compared to getting the TiXmlText child
|
|
|
|
and accessing it directly.
|
|
|
|
|
|
|
|
If the first child of 'this' is a TiXmlText, the GetText()
|
|
|
|
returns the character string of the Text node, else null is returned.
|
|
|
|
|
|
|
|
This is a convenient method for getting the text of simple contained text:
|
|
|
|
@verbatim
|
|
|
|
<foo>This is text</foo>
|
|
|
|
const char* str = fooElement->GetText();
|
|
|
|
@endverbatim
|
|
|
|
|
|
|
|
'str' will be a pointer to "This is text".
|
|
|
|
|
|
|
|
Note that this function can be misleading. If the element foo was created from
|
|
|
|
this XML:
|
|
|
|
@verbatim
|
|
|
|
<foo><b>This is text</b></foo>
|
|
|
|
@endverbatim
|
|
|
|
|
|
|
|
then the value of str would be null. The first child node isn't a text node, it is
|
|
|
|
another element. From this XML:
|
|
|
|
@verbatim
|
|
|
|
<foo>This is <b>text</b></foo>
|
|
|
|
@endverbatim
|
|
|
|
GetText() will return "This is ".

/**
|
|
|
|
A XMLHandle is a class that wraps a node pointer with null checks; this is
|
2012-04-05 05:00:07 +00:00
|
|
|
an incredibly useful thing. Note that XMLHandle is not part of the TinyXML
|
2012-03-29 00:27:55 +00:00
|
|
|
DOM structure. It is a separate utility class.
|
|
|
|
|
|
|
|
Take an example:
|
|
|
|
@verbatim
|
|
|
|
<Document>
|
|
|
|
<Element attributeA = "valueA">
|
|
|
|
<Child attributeB = "value1" />
|
|
|
|
<Child attributeB = "value2" />
|
|
|
|
</Element>
|
2012-05-12 12:21:23 +00:00
|
|
|
</Document>
|
2012-03-29 00:27:55 +00:00
|
|
|
@endverbatim
|
|
|
|
|
|
|
|
Assuming you want the value of "attributeB" in the 2nd "Child" element, it's very
|
|
|
|
easy to write a *lot* of code that looks like:
|
|
|
|
|
|
|
|
@verbatim
|
2012-04-05 05:00:07 +00:00
|
|
|
XMLElement* root = document.FirstChildElement( "Document" );
|
2012-03-29 00:27:55 +00:00
|
|
|
if ( root )
|
|
|
|
{
|
2012-04-05 05:00:07 +00:00
|
|
|
XMLElement* element = root->FirstChildElement( "Element" );
|
2012-03-29 00:27:55 +00:00
|
|
|
if ( element )
|
|
|
|
{
|
2012-04-05 05:00:07 +00:00
|
|
|
XMLElement* child = element->FirstChildElement( "Child" );
|
2012-03-29 00:27:55 +00:00
|
|
|
if ( child )
|
|
|
|
{
|
2012-04-05 05:00:07 +00:00
|
|
|
XMLElement* child2 = child->NextSiblingElement( "Child" );
|
2012-03-29 00:27:55 +00:00
|
|
|
if ( child2 )
|
|
|
|
{
|
|
|
|
// Finally do something useful.
|
|
|
|
@endverbatim
|
|
|
|
|
2012-04-05 05:00:07 +00:00
|
|
|
And that doesn't even cover "else" cases. XMLHandle addresses the verbosity
|
|
|
|
of such code. A XMLHandle checks for null pointers so it is perfectly safe
|
2012-03-29 00:27:55 +00:00
|
|
|
and correct to use:
|
|
|
|
|
|
|
|
@verbatim
|
2012-04-04 22:47:04 +00:00
|
|
|
XMLHandle docHandle( &document );
|
|
|
|
XMLElement* child2 = docHandle.FirstChild( "Document" ).FirstChild( "Element" ).FirstChild().NextSibling().ToElement();
|
2012-03-29 00:27:55 +00:00
|
|
|
if ( child2 )
|
|
|
|
{
|
|
|
|
// do something useful
|
|
|
|
@endverbatim
|
|
|
|
|
|
|
|
Which is MUCH more concise and useful.
|
|
|
|
|
|
|
|
It is also safe to copy handles - internally they are nothing more than node pointers.
|
|
|
|
@verbatim
|
2012-04-05 05:00:07 +00:00
|
|
|
XMLHandle handleCopy = handle;
|
2012-03-29 00:27:55 +00:00
|
|
|
@endverbatim
|
2012-04-05 05:00:07 +00:00
|
|
|
|
|
|
|
See also XMLConstHandle, which is the same as XMLHandle, but operates on const objects.

When loading, an XML parser is very useful. However, sometimes
|
|
|
|
when saving, it just gets in the way. The code is often set up
|
|
|
|
for streaming, and constructing the DOM is just overhead.
|
|
|
|
|
|
|
|
The Printer supports the streaming case. The following code
|
|
|
|
prints out a trivially simple XML file without ever creating
|
|
|
|
an XML document.
|
|
|
|
|
|
|
|
@verbatim
|
|
|
|
XMLPrinter printer( fp );
|
|
|
|
printer.OpenElement( "foo" );
|
|
|
|
printer.PushAttribute( "foo", "bar" );
|
|
|
|
printer.CloseElement();
