Unnecessary Text Anchors

Hey Everyone,

inDesign automatically added idText Anchors to my chapter headings. I have very short chapters and don't include them in the TOC. I'm inclined to remove these. Are there any good reasons to leave them in?

Second question, is there a way to quickly remove them rather than go line by line? Or more specifically, is there a way to use regex \d or similar to search <a id="_idTextAnchor024"></a></h3> so that \d replaces 024?

Thanks
