is there a tool that can help me to batch edit text files in a certain folder?
I need to delete or insert snippets repeatedly in lots of html files and restructure them.
Thanks in advance!

As Julian showed,
sed is the right tool for that.
I just want to add two remarks:
you can process multiple files at once, just by providing list of files:
sed -i.bak 's/old text/new text/' dir1/*.html dir2/*.html
Also, if you need to work with some Snippets manually, you can enable Snippets plugin in gedit:
Edit -> Preferences -> Plugins -> Snippets. You might find it handy.
sed, the stream editor, is your friend here. For example.
sed -i.bak -e's/<p id="first"/<p id="second"/' file.html
would change all the paragraphs with the id 'first' to id 'second' in file.html, and create file.html.bak into the bargain.
