Custom Plugin Installation Issue

Hi,
     I have created a custom resource, which works on an instance of Moodle 3.0.
I have another instance of the same version. When I try to install this plugin on the second instance, it gives me the following error:
Debug info: Errors found in XMLDB file: XML Error: Namespace prefix xsi for noNamespaceSchemaLocation on XMLDB is not defined at line 1.
Error code: ddlxmlfileerror


What could be the issue here?

I would assume that the message is true. Compare the first line or two of the xml file with a similar file from another (e.g. this one from mod_choice)

<?xml version="1.0" encoding="UTF-8" ?>
<XMLDB PATH="mod/choice/db" VERSION="20120122" COMMENT="XMLDB file for Moodle mod/choice"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="../../../lib/xmldb/xmldb.xsd"
>
  <TABLES>


...if it still looks ok, is there any chance you have edited it in something that might have damaged the character set or added extra (invisible) characters. Windows standard editors (like Notepad) are usually the problem here.

Hello Gayatri

Please delete your install.xml file.

And create again.
