Graham Mwebvendor in the entries list it would be applied to the url in the href

{{ entry.url|replace({('?__xtblog_block_id=1#xt_blog'):''}) }}

in the tags it would be a little more complex as you have to allow for the tag name variable

{{ tag.url|replace({('__xtblog_block_id=1&'):'',('#xt_blog'):''}) }}

it also is used in a few other places each may need a custom filter code due to other variables in the querystring
