Search and delete matches of patterns array - bash

Question

I made an array of filenames of files in which match an pattern:
lista=($(grep -El "<LastVisitedURL>.+</LastVisitedURL>.*<FavoriteTopic>0</FavoriteTopic>" *))
Now I would delete in a file index.xml all tags enclosure which contains the filenames in the array.
for e in ${lista[*]}
do
sed '/\<TopicKey FileName=\"$e\"\>.*\<\/TopicKey\>/d' index.xml
done
The complete script is:
#! /bin/bash
#search xml files watched and no favorites.
lista=($(grep -El "<LastVisitedURL>.+</LastVisitedURL>.*<FavoriteTopic>0</FavoriteTopic>" *))
#declare -p lista
for e in ${lista[*]}
do
sed '/<TopicKey FileName=\"$e\">.*<\/TopicKey>/d' index.xml
done
Even though the regex pattern doesn't work, -i option in sed for edit in place index.xml, reload index file many times how filenames have the array, and this is bad.
Any suggestions?

Here an example using xmlstarlet in a shell :
% cat file.xml
<?xml version="1.0"?>
<root>
<foobar>aaa</foobar>
<LastVisitedURL>http://foo.bar/?a=1</LastVisitedURL>
<LastVisitedURL>http://foo.bar/?a=2</LastVisitedURL>
<LastVisitedURL>http://foo.bar/?a=3</LastVisitedURL>
</root>
Then, the command line :
% xmlstarlet edit --delete '//LastVisitedURL' file.xml
<?xml version="1.0"?>
<root>
<foobar>aaa</foobar>
</root>
