the correction for the size issue was very simple. because it was a straight swap of fixed text, ie
size=x-large to size=6
there are no variables in those strings of text.
the issue with the url's. is that the following:
1 - each URL is different, so in order to fix them, i'd need to run the command for each URL.
2 - some of the URL's have http:// some have www. some dont have the www. part yet have the http:// par etc. too many variations.
3 - how to detetmin between the already tagged URL's and the untagged URL's.
4 - how to exclude all other URL's such as image url's, video clip url's etc.
its an impossible task, there are just too many variations.
