Find and replace help needed deleting multiple Word bookmarks

Question

I'm importing sections of a Word document. The Word documents have bookmarks such as:
    <h3><a name="_Toc226886762" id="_Toc226886762">Fixed-variable</a></h3>
I would like to do a sitewide search and replace, deleting all the bookmarks (they all start with Toc) but keeping the heading format and the text. I've tried various options, but nothing is working.
Thanks.

Answer 1

I just tried it again. When I clicked Replace All, the dialogue box disappeared. When I opened it again, I found a small square box at the end of the search string. When I tried to copy and paste it to here, it didn't show up.  <a name="_Toc[^>]+>([^<]+)</a>
When I was searching and getting no results, I had copied and pasted a section with only one bookmark in it. It was in the child of a template, but I can't see how that would make a difference.
Here's the code:
<div id="mainContent">
    <h2><a name="_Toc227356382" id="_Toc227356382">Combine  trips</a></h2>
    <p>Unless you live across the street from the grocery store,  consolidating shopping trips will save you time, gas, and reduce emissions. Unless  it’s a staple on sale, don’t buy what’s not on your list. </p>
    <p><em>Costco sells gasoline  for less than the local stations. We wait until the tank is close to empty and  the let the savings on gas pay for the trip.</em></p>
    <h2><a name="_Toc227356383" id="_Toc227356383">Compare  prices</a></h2>
    <p>Keep a small spiral notebook with prices of items you  purchase regularly such as rice, pasta, and dog food. A credit card size  calculator makes comparing prices easier.</p>
    <h2><a name="_Toc227356384" id="_Toc227356384">Check the  receipt</a></h2>
    <p>Computers don’t make mistakes, but operators do. If sales  prices aren’t entered into the system, the scanned price will reflect the  regular price. Some stores will give you the item for free if the scanned price  exceeds the price on the shelf. </p>
    <h2><a name="_Toc227356385" id="_Toc227356385">Price  matching</a></h2>
    <p>Some stores match competitors’ sales prices. Look for a sign  that says “Guaranteed low prices” and show them the ad. That can save you both  time and gas. Some promise to beat prices by 10%, so you can save money as  well. </p>
    <p>Many big box retailers demand exclusive manufacturer’s  numbers so they can evade making good on price matching guarantees.  The product may have a meaningless difference,  such as the color of the icons. </p>
