我无法从已解析的 Atom Feed 中获取条目。我正在从 Web 服务获取这些提要。事情是代码在我的本地服务器上工作得非常好，但是当我将它部署在我的开发盒上时，我得到了FOMUnsupportedTextTypeException异常。当我检查生成的 Atom 提要的差异时，我发现提要 xml 几乎没有变化。下面是我的local饲料

<atom:entry>
<atom:id>e0f7f5e7-a5f3-4a2e-a87d-d8def2b6bc2c</atom:id>
<atom:title">Locations</atom:title>
<atom:author>
<atom:uri>uid=wpsadmin,o=defaultWIMFileBasedRealm</atom:uri>
<atom:name>wpsadmin</atom:name>
</atom:author>

在这里我的 dev盒子生成了 xml。

<atom:entry>
<atom:id>e0f7f5e7-a5f3-4a2e-a87d-d8def2b6bc2c</atom:id>
<atom:title type="text/html">Locations</atom:title>
<atom:author>
<atom:uri>uid=wpsadmin,o=defaultWIMFileBasedRealm</atom:uri>
<atom:name>wpsadmin</atom:name>
</atom:author>

唯一的区别type="text/html"在于atom:title

我正在使用 abdera 解析器来解析 atom 并在本地和开发中使用 IBM Portal 8。

我收到此代码错误

Document<Feed> doc = response.getDocument();   
Feed feed = (Feed) doc.getRoot();   
for (Entry entry : feed.getEntries()) {  //exception at this line

例外是FOMUnsupportedTextTypeException

这是完整的异常详细信息

谁能告诉我如何从中删除type="text/html"属性atom:title？

正如Atom 规范所示，该提要不正确：

Text constructs MAY have a "type" attribute.  When present, the value
MUST be one of "text", "html", or "xhtml".  If the "type" attribute
is not provided, Atom Processors MUST behave as though it were
present with a value of "text".

Abdera 拒绝它是正确的。根据您的问题，Lotus Web Content Manager 似乎正在生成该提要；如果是这样，那是 WCF 中可能已修复的错误。如果这两个盒子产生不同的提要，也许它们运行不同的版本。

编辑：从您的另一个问题中，我可以看到您的代码正在从azeez:10039/wps/mycontenthandler/. 您需要弄清楚为什么您的两个环境在这里产生不同的提要，而不是试图修补无效数据。
