Finding parts of strings in http stream
I would like to find a way to extract strings from a stream returned from a http component. The strings i am looking for consists of unknown decimal numbers and there exact location is also unknown. The only thing that is known is a short string tag a unknown number av charcters before the wanted stringsegment.

To be more specific I want to find numerical data from html documents to put in my own database. A typical line (not necessairily in the begining of the stream) would be:
306 | <!-- plugg -->AGA A | -0.50 | 123.00 | 123.50 | 123.00 | 123.50 | 122.00 | 183025 | 22515630 | 0.38
where the text 'AGA A' is the known 'code' and the wanted numerical value is 123.00 (the first one). The problem is not with the http component. I am able to 'see' the text stream and put it in a memo-component or a textfile etc. I just need som intelligent way to extract the data I want.

For a quick and relevant answer I give everything I've got...
Could you post an example of what this string looks like? In general, the more "unknowns" when parsing a string, the more logic has to be built in to make it understandable to the application.
Also, the type of component your using might be relevant here. I have some code that parses strings from an NNTP component if that might be of value to you.
