XML DOCTYPE is disallowed when the feature set to true

Guidelines

I am trying to open an xml.gz file with the help of apoc.load.xml, but I get the following error:

Failed to invoke procedure apoc.load.xml: Caused by: org.xml.sax.SAXParseException; lineNumber: 2; columnNumber: 10; DOCTYPE is disallowed when the feature "http://apache.org/xml/features/disallow-doctype-decl" set to true.

I have no idea why this happens, it is independant of the compression config I use or if I try to load from a local file or from internet.

Expected Behavior (Mandatory)

The apoc.load.xml should open the file and display some values

Actual Behavior (Mandatory)

I get the following error when executing apoc.load.xml

Failed to invoke procedure apoc.load.xml: Caused by: org.xml.sax.SAXParseException; lineNumber: 2; columnNumber: 10; DOCTYPE is disallowed when the feature "http://apache.org/xml/features/disallow-doctype-decl" set to true.

How to Reproduce the Problem

Simple Dataset (where it's possibile)

The XML GZ files are available on https://ftp.ncbi.nlm.nih.gov/pubmed/updatefiles/

Steps (Mandatory)

If you simply execute the load.xml function you get the following error:

WITH "https://ftp.ncbi.nlm.nih.gov/pubmed/updatefiles/pubmed22n1219.xml.gz" AS url
CALL apoc.load.xml(url) YIELD value
UNWIND value AS article
RETURN article LIMIT 5

You can add the compression config but it doesn't help at all:

WITH "https://ftp.ncbi.nlm.nih.gov/pubmed/updatefiles/pubmed22n1219.xml.gz" AS url
CALL apoc.load.xml(url, "/", {compression:"GZIP"}) YIELD value
UNWIND value AS article
RETURN article LIMIT 5
