iphone - TouchXML 解析 XML 属性

Question

如何使用 touchXML 解析此 XML？我想将所有属性作为键/值对存储在字典中。

<Player PlayerName="Padraig HARRINGTON" CurrentPosition="1" CurrentRank="1"
    Country="IRL" NumberOfHolesPlayed="18" ParRelativeScore="+3">
    <RoundScore RoundNumber="1" Score="74" />
    <RoundScore RoundNumber="2" Score="68" />
    <RoundScore RoundNumber="3" Score="72" />
    <RoundScore RoundNumber="4" Score="69" />
</Player>
<Player PlayerName="Ian POULTER" CurrentPosition="2" CurrentRank="2" Country="ENG" 
    NumberOfHolesPlayed="18" ParRelativeScore="+7">
    <RoundScore RoundNumber="1" Score="72" />
    <RoundScore RoundNumber="2" Score="71" />
    <RoundScore RoundNumber="3" Score="75" />
    <RoundScore RoundNumber="4" Score="69" />
</Player>
<Player PlayerName="Henrik STENSON" CurrentPosition="3" CurrentRank="T3"           Country="SWE" 
    NumberOfHolesPlayed="18" ParRelativeScore="+9">
    <RoundScore RoundNumber="1" Score="76" />
    <RoundScore RoundNumber="2" Score="72" />
    <RoundScore RoundNumber="3" Score="70" />
    <RoundScore RoundNumber="4" Score="71" />
</Player>

我没问题，XML 的格式如下:

<Player>
<Country>UK</Country>
<NumberOfHolesPlayed>12</NumberOfHolesPlayed>
...
...

但我不确定在处理属性时该怎么做......

如何使用 touchXML 获取属性？特别是如果一个节点有一个子节点也有属性..

根据第一个示例 XML 文件。在第一个 XML 示例中，我设法获得了 Player 属性，但没有获得子节点的“RoundScore”属性。

很想伸出援助之手..

谢谢，

丹

是的!解决了您的问题。

请参阅以下代码。希望你能理解。它正在满足您的要求。我还添加了 - NSLog - 结果 - 已解析。

-(void)methodForParsingPlayers{
    NSMutableArray *ar=[[NSMutableArray alloc] init];
    CXMLDocument *doc=[[[CXMLDocument alloc] initWithData:[NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"Players" ofType:@"xml"]] options:0 error:nil] autorelease];

    NSArray *nodes=nil;
    nodes=[doc nodesForXPath:@"//Player" error:nil];

    NSString *strValue;
    NSString *strName;

    for (CXMLElement *node in nodes) {
        NSMutableDictionary *object=[[NSMutableDictionary alloc] init];

        // process to set attributes of object ----------------------------------------
        NSMutableDictionary *objectAttributes=[[NSMutableDictionary alloc] init];
        NSArray *arAttr=[node attributes];
        NSUInteger i, countAttr = [arAttr count];
        for (i = 0; i < countAttr; i++) {

            strName=[[arAttr objectAtIndex:i] name];
            if(strValue && strName){
