Hi,
I want to know how Regular Expression can be used in this situation.
I want to replace some string in specific condition..
The condition is to replace string only if the string is NOT inside of tag.
For example,
<Test id='wow'>wow</Test>
I want to replace the wow with great...So output will be
<Test id='wow'>great</Test>
As you know, if I just simply use 'wow' regular expression, it won't work...
Anybody knows what regular expression am I supposed to use?
Thanks,

Do you absolutely have to use a regular expression for this? Personally
I find that trying to work with XML using basic string handling is a
lot more error prone than using the XML APIs that are available. Is
there anything to stop you from iterating through all of the available
text nodes and just doing simple replacements within them?

Hi,
Thanks for your reply.
That's also one option I think.
However, actually, the input string is not XML.
I just gave the example for simplication.
Actual input string is HTML. It could be whole HTML, or part of HTML.
The thing I want is that I want to replace some string, if the string is NOT
inside of tag.
For example,
<Img src='wow.jpg'>w ow</img>
The output would be <Img src='wow.jpg'>g reat</img>
If you have any other idea other than regular expression, please share it
with us.
Thanks,

Regular expression examples for processing HTML are all over the web. Here's
the third hit I got from Google for "html regex tag", for example: http://haacked.com/archive/2004/10/2...matchhtml.aspx
However, if you want to do it right and take into account things like
unclosed tags ("<br>"), mismatched tags and CDATA sections, a regex will not
help you (or else it'll be way too complicated to write); you'll need an
actual HTML parser. Google suggests there are multiple for .NET, some of
which might be useful.

Hi,
I am replaceing a big string using different regular expressions (see
some example at the end of the message). The problem is whenever I
apply a "replace" it makes a new copy of string and I want to avoid
that. My question here is if there is a way to pass either a memory
stream or array of "find", "replace" expressions or any other way to
avoid multiple copies of a string.
Any help will be highly appreciated

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
