XML文件，请注意，这是只是一个样本，因为我希望该计划之前，我开始填补这个仓库工作

<repo> 
<Packages> 
    <TheFirstPackage id="00001" longname="Mozilla Firefox" appver="3.6.3" pkgver="0.01" description="Mozilla Firefox is a free and open source web browser descended from the Mozilla Application Suite and managed by Mozilla Corporation. A Net Applications statistic put Firefox at 24.52% of the recorded usage share of web browsers as of March 2010[update], making it the second most popular browser in terms of current use worldwide after Microsoft's Internet Explorer." cat="WWW" rlsdate="4/8/10" pkgloc="http://google.com"/> 
</Packages> 
<categories> 
    <WWW longname="World Wide Web" description="Software that's focus is communication or primarily uses the web for any particular reason."> </WWW> 
    <Fun longname="Entertainment & Other" description="Music Players, Video Players, Games, or anything that doesn't fit in any of the other categories."> </Fun> 
    <Work longname="Productivity" description="Application's commonly used for occupational needs or, stuff you work on"> </Work> 
    <Advanced longname="System & Security" description="Applications that protect the computer from malware, clean the computer, and other utilities."> </Advanced> 
</categories> 
</repo>

C＃代码的小部分

//Loading the Package and Category lists 
       //The info from them is gonna populate the listboxes for Category and Packages 
       Repository.Load("repo.info"); 
       XmlNodeList Categories = Repository.GetElementsByTagName("categories"); 
       foreach (XmlNode Category in Categories) 
       { 
        CategoryNumber++; 
        CategoryNames[CategoryNumber] = Category.Name; 
        MessageBox.Show(CategoryNames[CategoryNumber]); 
       }

的Messagebox.Show（）是只是为了确保它得到正确的结果

＆符号在XML特殊的意义。您需要更改：

Entertainment & Other

在这个人物的地方使用character entity reference：

Entertainment &amp; Other

这同样适用于System & Security。

在一天内更换，并确保当你在它正确转义任何其它字符，以防万一< or >单。 – ssube 2010-05-01 17:34:40

...或者“在属性值的某个位置上的附属物”。 – 2010-05-01 19:05:01

您在xml'&'中有无效字符。

更新：与&
