|
Lee Thomason | 3ffdd39 | 2012-03-28 17:27:55 -0700 | [diff] [blame] | 1819 | easy to write a *lot* of code that looks like:
|
| 1820 |

| 1821 | @verbatim

|

|

|

|
Lee Thomason (grinliz) | ae209f6 | 2012-04-04 22:00:07 -0700 | [diff] [blame] | 1837 | And that doesn't even cover "else" cases. XMLHandle addresses the verbosity
|
Lee Thomason (grinliz) | 2f1f624 | 2012-09-16 11:32:34 -0700 | [diff] [blame] | 1838 | of such code. A XMLHandle checks for null pointers so it is perfectly safe
|
Lee Thomason | 3ffdd39 | 2012-03-28 17:27:55 -0700 | [diff] [blame] | 1839 | and correct to use:
|
| 1840 |
|
| 1841 | @verbatim
|
Lee Thomason | db0bbb6 | 2012-04-04 15:47:04 -0700 | [diff] [blame] | 1842 | XMLHandle docHandle( &document );
|
Dmitry-Me | a317bd6 | 2014-12-08 10:35:37 +0300 | [diff] [blame] | 1843 | XMLElement* child2 = docHandle.FirstChildElement( "Document" ).FirstChildElement( "Element" ).FirstChildElement().NextSiblingElement();
|
Lee Thomason | 3ffdd39 | 2012-03-28 17:27:55 -0700 | [diff] [blame] | 1844 | if ( child2 )
|
| 1845 | {
|
| 1846 | // do something useful
|
| 1847 | @endverbatim
|
| 1848 |
|
| 1849 | Which is MUCH more concise and useful.
|
| 1850 |
|
| 1851 | It is also safe to copy handles - internally they are nothing more than node pointers.
|
| 1852 | @verbatim
|
Lee Thomason (grinliz) | ae209f6 | 2012-04-04 22:00:07 -0700 | [diff] [blame] | 1853 | XMLHandle handleCopy = handle;

|
| 2034 | When loading, an XML parser is very useful. However, sometimes
|
| 2035 | when saving, it just gets in the way. The code is often set up

|
| 2037 |
|
| 2038 | The Printer supports the streaming case. The following code

|
| 2040 | an XML document.
