Tinyxml read/write xml Sample code

TinyXML is an open-source parsing XML library that can be used in C ++ and compiled in Windows or Linux. The parsing library's model parses the XML file and then generates the DOM model in the memory, so that we can easily traverse this XML tree.

The DOM model is a Document Object Model. It divides a document into multiple elements (such as books, chapters, sections, and segments ), the tree structure is used to represent the ordered relationship between these elements and the nested inclusion relationship.

The following is an XML snippet:

In TinyXML, some classes are defined based on various elements of XML:

TiXmlBase: the base class of the entire TinyXML model.

TiXmlAttribute: attribute corresponding to the element in XML.

TiXmlNode: corresponds to a node in the DOM structure.

TiXmlComment: corresponding to the comment in XML

TiXmlDeclaration: corresponds to the declarative part in XML, that is, <? Versiong = "1.0"?>.

TiXmlDocument: corresponds to the entire XML document.

TiXmlElement: elements corresponding to XML.

TiXmlText: text part corresponding to XML

TiXmlUnknown: corresponds to the unknown part of XML.

TiXmlHandler: defines some XML operations.

TinyXML is a parsing library mainly composed of DOM model classes (TiXmlBase, TiXmlNode, TiXmlAttribute, TiXmlComment, TiXmlDeclaration, TiXmlElement, TiXmlText, TiXmlUnknown) and Operation class (TiXmlHandler.

The tinyxml component is very convenient for reading and writing XML, which is easier than boost.

The following is a template file for xml reading and writing.

<? Xml version = "1.0" encoding = "UTF-8" standalone = "yes"?> <Savemaplist> <map mapid = "1" name = "Dota v8.w3x" filename = "Dota_V7.8.w3x" md5 = "Encrypt"/> <map mapid = "2" name = "Dota v9.w3x "filename =" Dota_V1.8.w3x "md5 =" yellow "/> <map mapid =" 3 "name =" Dota v11.w3x "filename =" Dota_V2.8.w3x "md5 =" yellow "/> </savemaplist>

Read/Write code

Some required types

Struct rpgMapData {int mapid; std: string md5; std: wstring showmapname; // display name std: wstringsavename; // storage name bool haddownload; rpgMapData () {mapid = 0; md5 = ""; showmapname = L ""; haddownload = false;} rpgMapData (int v): mapid (v) {md5 = ""; showmapname = L ""; haddownload = false;} bool operator = (const rpgMapData & _ R) const {return mapid = _ R. mapid ;}};
