使用iPhone将更多项目添加到xml文件 [英] Add more items to xml file using iphone

问题描述

有人帮助我，我正在使用一个xmlfile

Hi some body help me I am using one xmlfile like

<?xml version="1.0" encoding="UTF-8"?> 
<MangoUserDataFile>
    <Device>iPad</Device>
    <Version>3.0</Version>
        <UserName>XYZ</UserName>
        <UserType>Admin</UserType>  
        <Module>TabView</Module>    
        <tab id="1">
        <item>
                  <name>Admin</name>
                  <value>WebView</value>
                  <image>20</image>
               </item>
        </tab>
</MangoUserDataFile>

我想从iPad上在此xml文件中添加更多项目

I want to add more items in this xmlfile from IPad

例如，我正在创建一些名为:

For exmaple, I am creating some textfields called:

nametextfiled ， valuetextfiels ， imagetextfield

...，当我在这些文本字段中输入值并单击提交时，应在这些XML文件中创建另一个项目

... and once I enter the value in these textfields and click to submit at that time another items should be created in these XML File

有人可以给我任何有关如何从IPad向xmlfile添加另一个项目的想法吗.

Can some body give me any ideas on this how we add another item in xmlfile from IPad.

推荐答案

在这种情况下，您应该将所有元素重写到一个新的XML文件中，并尝试用新的XML文件替换旧的XML文件.

In that case you should rewrite all the elements into a new XML file, and try to replace the old XML file with the new one.

可以使用以下类进行书写:
