The xmldom class implements a minimal XML DOM parser.
xmldom::xmldom | ( | ) |
Creates a new instance of the xmldom class.
xmldom::xmldom | ( | bool | stringcacheenabled | ) |
Creates a new instance of the xmldom class, allowing the user to enable or disable the "string cache" for this instance.
By default, as each xmldomnode is added to the xmldom tree, tag and attribute names and values are stored in a string cache and pointers into the cache are assigned to each node. Reference counters are kept and the string is removed from the cache when no more nodes are using it. As xml tends to be highly repetitive this conserves memory at the cost of speed.
If the string cache is disabled then memory is allocated in each xmldomnode for names and values and freed when the xmldomnode is freed. This is faster but uses much more memory.

virtual |
Deletes this instance of the xmldom class.
void xmldom::createRootNode | ( | ) |
Creates a new root node. This is useful for building a tree from scratch.
xmldomnode* xmldom::getNullNode | ( | ) | const |
Returns the null node of the DOM tree.
xmldomnode* xmldom::getRootNode | ( | ) | const |
Returns the root node of the DOM tree.
|
virtual |
Parses file "filename" and generates a DOM tree.
Reimplemented from xmlsax.
|
virtual |
Parses string "string" and generates a DOM tree.
Reimplemented from xmlsax.
bool xmldom::stringCacheEnabled | ( | ) |
Returns true if the string cache is enabled and false if it is disabled.
bool xmldom::writeFile | ( | const char * | filename, |
mode_t | perms | ||
) | const |
Writes the current DOM tree to "filename" and sets permissions of the file to "perms".
