Validating Magento 2 XML files about exalt

[eerohele]

Your misc.xml doesn't look like an OASIS XML catalog file, which is the only kind of catalog Exalt supports.

Can you try replacing misc.xml with an OASIS XML catalog? I think something like this should work:

<?xml version="1.0" encoding="utf-8"?>

<!DOCTYPE catalog
  PUBLIC "-//OASIS//DTD Entity Resolution XML Catalog V1.0//EN"
         "http://www.oasis-open.org/committees/entity/release/1.0/catalog.dtd">

<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog">
  <uri
    name="urn:magento:framework:Setup/Declaration/Schema/etc/schema.xsd"
    uri="ROOT/vendor/Magento/framework/Setup/Declaration/Schema/etc/schema.xsd"/>
</catalog>

It's been a while since I've worked with this stuff, though, so you might need to fiddle with that a bit.

Thank you I got it working:

<?xml version="1.0" encoding="utf-8"?>

<!DOCTYPE catalog
  PUBLIC "-//OASIS//DTD Entity Resolution XML Catalog V1.0//EN"
         "http://www.oasis-open.org/committees/entity/release/1.0/catalog.dtd">

<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog">
    <uri name="urn:magento:framework:Setup/Declaration/Schema/etc/schema.xsd" uri="file:///D:/path/to/installation/vendor/magento/framework/Setup/Declaration/Schema/etc/schema.xsd"/>
    <uri name="urn:magento:framework:ObjectManager/etc/config.xsd" uri="file:///D:/path/to/instllation/vendor/magento/framework/ObjectManager/etc/config.xsd"/>
    .
    .
    .
</catalog>

By the way, I think you could also do something along these lines:

<rewriteURI uriStartString="urn:magento:framework:" rewritePrefix="file:///D:/path/to/installation/vendor/magento/framework/"/>

I didn't test, though.

The exact same statement worked great and saved tens of kilobytes!
Thank you

I'm nothing if not prudent when it comes to kilobytes.

Glad to hear it works!
