本文主要是介绍xml读写--谁知道这几个方法怎么用都需要什么框架（请留言），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
创建XML文件
- //创建XML文件
- - (NSXMLDocument *)createXMLDocument:(NSString *)rootName{
- NSLog(@"%@ with rootName %@", NSStringFromSelector(_cmd), rootName);
- NSXMLElement *root = (NSXMLElement *)[NSXMLNode elementWithName:rootName];
- [root addAttribute:[NSXMLNode attributeWithName:@"version" stringValue:@"1.0"]];
- NSXMLDocument *xmlDoc = [[NSXMLDocument alloc] initWithRootElement:root];
- [xmlDoc setVersion:@"1.0"];
- [xmlDoc setCharacterEncoding:@"UTF-8"];
- [xmlDoc setRootElement:root];
- return [xmlDoc autorelease];
- }
2. 装载XML文件
- - (NSXMLDocument *)loadXMLDocument:(NSString *)xmlFilePath{
- assert(xmlFilePath);
- NSXMLDocument *xmlDoc = nil;
- NSError *error = nil;
- @try {
- NSURL *fileURL = [NSURL fileURLWithPath:xmlFilePath];
- if (fileURL == nil) {
- return nil;
- }
- xmlDoc = [[NSXMLDocument alloc] initWithContentsOfURL:fileURL options:NSXMLDocumentTidyXML error:&error];
- }
- @catch (NSException * e) {
- }
- @finally {
- return [xmlDoc autorelease];
- }
- }
3. 保存XML文件
- - (BOOL) saveXMLFile:(NSString *)destPath :(NSXMLDocument *)xmlDoucment{
- if (xmlDoucment == nil) {
- return NO;
- }
- if ( ! [[NSFileManager defaultManager] fileExistsAtPath:destPath]) {
- if ( ! [[NSFileManager defaultManager] createFileAtPath:destPath contents:nil attributes:nil]){
- return NO;
- }
- }
- NSData *xmlData = [xmlDoucment XMLDataWithOptions:NSXMLNodePrettyPrint];
- if (![xmlData writeToFile:destPath atomically:YES]) {
- NSLog(@"Could not write document out...");
- return NO;
- }
- return YES;
- }
4. 生成CData节点
- - (NSXMLNode *)generateCDataNode:(NSString *)value {
- <span style="white-space:pre"> </span>NSXMLNode *cdataNode = [[NSXMLNode alloc] initWithKind:NSXMLTextKind options:NSXMLNodeIsCDATA];
- <span style="white-space:pre"> </span>[cdataNode setStringValue:value];
- <span style="white-space:pre"> </span>
- <span style="white-space:pre"> </span>return [cdataNode autorelease];
- }
可以像下面这样使用：
- NSXMLElement *urlNode = [NSXMLElement elementWithName:@"Setting"];
- NSXMLNode *cdataNode = [self generateCDataNode:dmgFileName];
- [urlNode addAttribute:[NSXMLNode attributeWithName:@"name" stringValue:name]];
- [urlNode addAttribute:[NSXMLNode attributeWithName:@"type" stringValue:type]];
- [urlNode addChild:cdataNode];
生成的Xml节点如下：
- <Setting name="OutputFileName" type="string"><![CDATA[mac-data-recovery_full737.dmg]]></Setting>
