本文介绍了TouchXML解析XML属性的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
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。
How do I use touchXML to parse this XML? I want to store all the attributes as key/value pairs in a dictionary.
<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>
我没有问题是XML格式如下：
I have no problem is the XML is formatted like so:
<Player>
<Country>UK</Country>
<NumberOfHolesPlayed>12</NumberOfHolesPlayed>
...
...
但是我不知道在处理属性时该怎么做...
But I'm not sure what to do when dealing with attributes...
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..
How can you get attributes with touchXML? In particular if a node has a subnode that also has attributes..
按照第一个例子XML文件。在第一个XML示例中，我设法获取Player属性，但没有子节点的RoundScore属性。
As per the first example XML file. In the first XML example I managed to get the Player attributes but not the child nodes 'RoundScore' attributes.
希望有助于帮助。
感谢，
Dan

是的！解决了您的问题。
Yep ! solved your problem.
请参阅以下代码。希望你能理解。
它为您的要求工作。我还添加了 - NSLog - Result - parsed。
see, following code. Hope you understand. It's working for your requirement. I also have added - NSLog - Result - parsed.
