Search through list of HTML files to find file names
I have a list of HTML files in listbox1. I need the delphi code to search through these to find any file names mentioned in the code and add these to grid1 thus:
First column: the HTML file that the file name is mentioned in.
Second column: the found file name.
Third column: position where the file name was found.
I am using Delphi 6. I am giving the maximum 500 points for this. Many thanks for your help.

I mean the HTML code of the HTML files.
What's the definition of a filename? Do you consider \\Server\Share\Folder\File
Depending of what you're looking for, search for the characters '//', '\\' or just ':\' and use some smart algorithm to determine if it is part of what you consider to be a filename.
Of course, if you're just looking for links, search for the <a> tag or the <img> tag in the file, since they will refer to other files. But first make clear what exactly it is you're looking for since the text 'filename' itself could already be a valid filename while 'c:\folder.txt' could actually be a foldername instead of a filename...

I have HTML files that does not contain self file name inside self content.
How it will be determined > First column: the HTML file that the file name is mentioned in. ?

Even worse: c:\<b>folder</b>\Filename.
When the user would see above text, he would see a valid filename, with the 'folder' part in a bold font. But would you consider it a valid filename or not? :-)

As an example, I need to go through the HTML code of each HTML file in the listbox and extract the links such as (for example):
<A href="http://www.demo.com/purchase.cgi">Order</A>
In the above example, I would want the grid to display:
index.htm http://www.demo.com/purchase.cgi 100
"index.htm" is the name of the file in the listbox. "http://www.demo.com/purchase.cgi" is the link in the searched HTML file. 100 is the character position where the link starts.
IMPORTANT: it will not always be absolute links as above. It could be just the filename (purchase.cgi) or any folder names before it (cgi-bin/shop/purchase.cgi
Also it will not always be an actual link ("A href" in the html code). It could be an image (the HTML code is diffrerent) or a POST to a cgi file) or whatever.
Hope this clarifies things. Thanks.
