Hi,
did you manage to fix the issue? i could not see what you described in your web site.
for security reasons it is not recommended to copy full html sections from an untrusted source, so the best option is to strip the data before it you insert it to your collection. there are online tools that can help you with that. in addition you will have to do the striping before displaying the data anywhere in your website
regarding the other question you had, please have a look here:
