I want to use Custom Meta tags in my HTML to hold special information about
the pages. Then I want to retrieve this information to store externally so
I can do things like search it, etc. For example:

<meta name="myCustomTag" content="this is the value">

Is using regular expressions the way to go to retreive this data? If it is,
can anyone give me and example of how I might do this?

Thanks

Regular expressions would handle this quite nicely. Do you want to
retrieve all meta tags or just specific ones?

Something like: "<meta name=\"(MyCustomTag1|MyCustomTag2|MyCustomTag3)\"
content=\"(.*?)\">"

Would give you basically name values pairs.

Put the specific names in the (xx|xx|xx|xx) part, (names divided by |).

Heres basically the code I am using:

RegEx findData = new Regex("<meta
name=\"(MyCustomTag1|MyCustomTag2|MyCustomTag3)\" content=\"(.*?)\">");
Match foundData = findData.Match(sSomeString);

while (foundData.Success)
foreach (Capture c in foundData.Captures) {
Response.write(m.Value)
}
}

This results in the entire <meta> tag being written out. Do I then need to
parse the string futher to get the name value pair?

What you do to get the name and value is make them sub-matches

Can you point me to some example C# or VB.NET code. I looked in the
documentation, but it seemed like everything which had to do with SubMatches
collection was for VBS not C# or VB.NET.

I'm not sure how the captures collection is supposed to be used. What
I've done in the past is like so:

MatchCollection foundData = findData.Matches(sSomeString);

for(int I = 0; I < foundData.Count; i++)

{

arrMyMatch = foundData[i].Result("$1,$2").Split(',');

MyNameValueCollection.Add(arrMyMatch[0],arrMyMatch[1]);

}

which would result in MyNameValueCollection containing all the
name/value pairs.

This should to the trick take a look at:

l/cpconregularexpressionsaslanguage.asp
<http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/ht
ml/cpconregularexpressionsaslanguage.asp>

string sSomeString = "<meta name=\"myCustomTag1\" content=\"Tag1
value\">\n<meta name=\"myCustomTag2\" content=\"Tag2 value\">";
string pattern = "<meta name=\"(?<name>myCustomTag1|myCustomTag2)\"
content=\"(?<value>.*?)\">";
Regex r = new Regex(pattern, RegexOptions.IgnoreCase);

Match m;
for (m = r.Match(sSomeString); m.Success; m = m.NextMatch())
{
Response.Write(m.Groups["name"]);
Response.Write(m.Groups["value"]);
}

RE: [aspngregexp] RE: Retrieving tag attributesBy the way, if you can make sure that the page (or at least the <head> section) is valid XML, you can use the XML parser to grab your name and value from the tags. Might be easier than a regex, might not...
