Deleting an XML tag in a huge file

I have difficulty parsing a huge XML file (about 100GB with large nodes). I am trying to reduce the node sizes by deleting unnecessary tags. For example, any `` tags. If I use native XML parsers such as xmlstarlet xmlstarlet ed -P -d '//text' file.xml I face the same problem of being out of memory. Is there a safe way (with little memory footprint) to remove all `` pairs without breaking the XML structure?
