用IE阅读RSS XML [英] Reading RSS XML with IE
问题描述
将rss源加载到Windows IE时，doc.childNodes.length总是
等于0.如果我手动删除<！DOCTYPE标签doc.childNodes.length
是正确的。
我正在使用
doc = new ActiveXObject（" Microsoft.XMLDOM"）;
加载rss。这是问题所在吗？
（使用带有FF的document.implementation.createDocument在有或没有DOCTYPE的情况下正确读取XML
。）

很难说，我们需要查看更多代码，无论是同步加载
还是异步加载。
使用的一些设置是
doc.resoveExternals = false
doc.validateOnParse = false
究竟是怎样的那样做！DOCTYPE声明看起来像？ XML
对于声明的文档类型是否有效？
你有没有检查过
doc.parseError.errorCode
doc.parseError.reason
虽然Mozilla使用Expat非验证解析器忽略
externals资源IE使用MSXML和MSXML可以验证DTD 。
如果你想验证DTD，那么你需要检查
是否存在parseError。

那究竟是怎么做的！DOCTYPE声明是什么样的？ XML对于声明的文档类型是否有效？
您是否检查过doc.parseError.errorCode
doc.parseError.reason
检查错误原因。我将RSS源复制到我的硬盘上
我必须无意中编辑了标签名称。

我说得太早了。我尝试从这个链接解析RSS：
< url： http://www.nasa.gov/rss/image_of_the_day.rss >
但IE告诉我使用元素''rss''但不是在
DTD / Schema中声明。
这对我来说似乎很奇怪。这是否意味着XML本身无效或者b
有一些我无法访问的资源导致了
问题。

When loading an rss feed into Windows IE, doc.childNodes.length always
equals 0. If I manually delete the <!DOCTYPE tag doc.childNodes.length
is correct.
I''m using
doc = new ActiveXObject("Microsoft.XMLDOM");
to load the rss. Is this where the problem lies?
(Using document.implementation.createDocument with FF reads the XML
correctly with or without a DOCTYPE.)

Hard to tell, we need to see more code, whether you load synchronously
or asynchronously.
Some settings to play with are
doc.resoveExternals = false
doc.validateOnParse = false
And how exactly does that !DOCTYPE declaration look like? Is the XML
valid in regard to that declared document type?
Have you checked
doc.parseError.errorCode
doc.parseError.reason
While Mozilla uses with Expat a non validating parser that ignores
externals resources IE uses MSXML and MSXML can validate against a DTD.
If you want to validate against the DTD then you need to check whether
there is a parseError.

Checking the error reason did it. I copied the RSS feed to my hard drive
and I must''ve inadvertently edited a tag name.

I spoke too soon. I tried parsing the RSS from this link:
<url: http://www.nasa.gov/rss/image_of_the_day.rss >
but IE tells me that "The element ''rss'' is used but not declared in the
DTD/Schema."
This seems odd to me. Does this mean that the XML itself is invalid or
that there''s some resource that I don''t access to that is causing the
problem.
