Regex Validator - 检测除特定HTML标记之外的所有标记 [英] Regex Validator - detect all but certain HTML tags
问题描述
大家好......希望有人可以提供帮助。
不是一个独特的情况，但我对解决方案的搜索没有产生/>
我还需要什么。
我正在尝试为一个
RegularExpressionValidator提供一个正则表达式，它将允许某些HTML标记：
< a>，< b>，< blockquote>，< br>，< i>，< img>，< li>， < ol>，< p>，< quote>，
< ul>
但阻止他人。所以基本上我想要检测<然后寻找
某些序列（上面的标签）。但我当然也要为
帐户提供任意数量的可能属性。然后上面的一些
标签有结束标签，有些没有。
我不完全理解正则表达式，但想学习;
但是，我也希望尽快找到一种方法。
我不想重新发明这个特殊的轮子。如果你之前已经完成了
，如果你知道我的意思。 :)
任何人的帮助都会非常感激。谢谢
很多！

我需要找一个正则表达式验证器的正则表达式来执行我所描述的
。
我不是对解析网页感兴趣。我正在尝试解析文本框中的
内容 - 我有一个DetailsView控件，其中一个
文本框用于可能显示在.aspx中的内容页。我希望
允许某些标签，但阻止所有其他标签。 DetailsView被绑定到一个ObjectDataSource，所以很自然地，如果可能的话，让
Validator为我捕获所有内容会很好。
任何想法（任何人）？
谢谢，
Barry

您可以将文本框内容加载到MSHTML中。
查找正则表达式来处理HTML的所有情况将是
至少可以说 - 我建议你再看看MSHTML
，看看它是否能正常工作。
Hi all... hope someone can help out.
Not a unique situation, but my search for a solution has not yielded
what I need yet.
I''m trying to come up with a regular expression for a
RegularExpressionValidator that will allow certain HTML tags:
<a>, <b>, <blockquote>, <br>, <i>, <img>, <li>, <ol>, <p>, <quote>,
<ul>
but block others. So basically I''d like to detect "<" then look for
certain sequences (the tags above). But I also of course have to
account for any number of possible attributes. And then some of the
tags above have closing tags, others do not.
I don''t fully understand regular expressions, yet would like to learn;
however, I also want to find a way to do this soon.
I don''t want to reinvent this particular "wheel" if it has already been
done before, if you know what I mean. :)
Any help from anyone out there would be greatly appreciate. Thanks
Much!

Barry,
When you do not want to invent the wheel, than why do you not use the wheel
that is invented for this?
MSHTML.

I need to find a regex for Regular Expression Validator to perform what
I am describing.
I''m not interested in parsing a web page. I''m trying to parse the
contents of a textbox - I have a DetailsView control, for which one
textbox is for content that may be displayed in an .aspx page. I want
to allow certain tags, but block all others. The DetailsView is bound
to an ObjectDataSource, so naturally it would be nice to have the
Validator catch everything for me if at all possible.
Any ideas (anyone)?
Thanks,
Barry

Finding a regular expression to handle all the cases of HTML will be
challenging to say the least - I suggest you take a look at MSHTML again
and see if it''ll work.
