Hi,
 
We are using XOM to communicate XML over the internet and need to protect
ourselves from XML hacks such as mentioned on:
 <https://www.owasp.org/index.php/XML_External_Entity_%28XXE%29_Processing>
https://www.owasp.org/index.php/XML_External_Entity_%28XXE%29_Processing
 
What is the most straight-forward way to configure XOM to achieve this?
 
Currently we are just doing:
    Builder builder = new Builder();
    Document doc = builder.build(new StringReader(xmlstr));
 
Thanks
Mike
