Shell script to download files from anywhere

As the title suggests, this is just a simple script I figured out for downloading files. The list of urls for downloading are located in an xml document that I'm parsing, storing briefly, looping through and downloading what I wanted to a predetermined location (though that could be modified for user input).

Script:

read_dom () {
    local IFS=\>
    read -d \< ENTITY CONTENT
}

while read_dom; do
    if [[ $ENTITY = "xmlTag" ]]; then
echo $CONTENT
if [[ $CONTENT != "null" ]]; then
wget -Nrkpl 0 $CONTENT -nd -Pdownloads
fi      
    fi
done < listOfXML.xml > temporaryXMLPage.txt

echo "File cleanup"
rm temporaryXMLPage.txt
