## Detailed Description

The xmldom class implements a minimal XML DOM parser.

## Constructor & Destructor Documentation

## xmldom() [1/2]

xmldom::xmldom | ( |  | ) |

Creates a new instance of the xmldom class.

## xmldom() [2/2]

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 domnode 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. If the data is highly repetitive this conserves memory at the cost of speed.

If the string cache is disabled then memory is allocated in each domnode for names and values and freed when the domnode is freed. This is faster but uses much more memory.

## ~xmldom()

virtual xmldom::~xmldom | ( |  | ) |

virtual

Deletes this instance of the xmldom class.

## Member Function Documentation

## attributeName()

virtual bool xmldom::attributeName | ( | const char * | name | ) |

protected virtual

Gets called when an attribute name is parsed.

Reimplemented from xmlsax.

## attributeValue()

virtual bool xmldom::attributeValue | ( | const char * | value | ) |

protected virtual

Gets called when an attribute value is parsed.

Reimplemented from xmlsax.

## cdata()

virtual bool xmldom::cdata | ( | const char * | string | ) |

protected virtual

Gets called when cdata is parsed.

Reimplemented from xmlsax.

## comment()

virtual bool xmldom::comment | ( | const char * | string | ) |

protected virtual

Gets called when a comment is parsed.

Reimplemented from xmlsax.

## createRootNode()

void xmldom::createRootNode | ( |  | ) |

virtual

Creates a new root node. This is useful for building a tree from scratch.

Reimplemented from dom.

## parseFile()

bool xmldom::parseFile | ( | const char * | filename | ) |

virtual

Parses file "filename" and generates a DOM tree.

Implements dom.

## parseString()

bool xmldom::parseString | ( | const char * | string | ) |

virtual

Parses string "string" and generates a DOM tree.

Implements dom.

## tagEnd()

virtual bool xmldom::tagEnd | ( | const char * | ns,
|  | const char * | name
| ) |  |

protected virtual

Gets called when an end tag is parsed.

Reimplemented from xmlsax.

## tagStart()

virtual bool xmldom::tagStart | ( | const char * | ns,
|  | const char * | name
| ) |  |

protected virtual

Gets called when a start tag is parsed.

Reimplemented from xmlsax.

## text()

virtual bool xmldom::text | ( | const char * | string | ) |

protected virtual

Gets called when a block of text is parsed.

Reimplemented from xmlsax.
