Hi Team,
I am unable to open xml with <!ENTITY > markup in web author. below is the error I got on load.

Document could not be loaded
Details:
Blocked entity "%entity_file" whose target has a different protocol than the file where it was declared.

From network log in developer toolbar load request returned http 400 with Json response "{"type": "io_error","message":"Blocked entity \"%entity_file\" whose target has a different protocol than the file where it was declared."}"

Sample XML File.

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xampex [
<!ENTITY % entity_file SYSTEM "http://localhost/jwblinks/schema/allchars-numeric.ent"> %entity_file;]>

Please let know if I am missing something here while loading xml.

Hello,

There is an option called block.cross.protocol.system.entities [1] that, when it is set to true (the default), blocks the XML external entities if their target URL does not have the same protocol as the URL of the file where the entity is declared (from what I see in the logs your document is opened from a webdav server).
You can set the option to false [2] if you want to change this behavior.
