How to split a single XML file into multiple based on tags

I have an XML file that have tags. I want to split files like this.

<?xml version="1.0" encoding="UTF-8"?>
<EMPRMART CREATION_DATE="08/20/2018 18:06:44" REPOSITORY_VERSION="187.96">
<REPOSITORY NAME="REP_DEV" VERSION="187" CODEPAGE="UTF-8" DATABASETYPE="Sybase">
<FOLDER NAME="MC_DEV" 
    <CONFIG DESCRIPTION ="Default ORDER configuration object" ISDEFAULT ="YES" NAME ="default_ORDER_config" VERSIONNUMBER ="1">
        <ATTRIBUTE NAME ="Advanced" VALUE =""/>
        <ATTRIBUTE NAME ="Order type" VALUE ="NO"/>
    </CONFIG>
    <ORDER DESCRIPTION ="" ISVALID ="YES" 
        <ATTRIBUTE NAME ="Normal" VALUE =""/>
        <ATTRIBUTE NAME ="Order type" VALUE ="NO"/>
    </ORDER>
    <ORDER DESCRIPTION ="" ISVALID ="YES" 
        <ATTRIBUTE NAME ="Medium" VALUE =""/>
        <ATTRIBUTE NAME ="Order type" VALUE ="NO"/>
    </ORDER>
    <ORDER DESCRIPTION ="" ISVALID ="YES" 
        <ATTRIBUTE NAME ="Advanced" VALUE =""/>
        <ATTRIBUTE NAME ="Order type" VALUE ="NO"/>
    </ORDER>
    <LOCATION DESCRIPTION ="" ISENABLED ="YES" 
    </LOCATION>
</FOLDER>
</REPOSITORY>
</EMPRMART>

Below is the code tried . But it is generating every single line into a new file

awk  '
    BEGIN { RS = "</ORDER>" } 
    $0 ~ /[^[:blank:]n]/ { 
        printf "%sn", $0 RS >> FILENAME "_" ++i ".xml" 
    }
' test.xml

I want to split this file based on ORDER tags alone as mentioned below

File1.xml
    <ORDER DESCRIPTION ="" ISVALID ="YES" 
        <ATTRIBUTE NAME ="Normal" VALUE =""/>
        <ATTRIBUTE NAME ="Order type" VALUE ="NO"/>
    </ORDER>        
File2.xml
    <ORDER DESCRIPTION ="" ISVALID ="YES" 
        <ATTRIBUTE NAME ="Medium" VALUE =""/>
        <ATTRIBUTE NAME ="Order type" VALUE ="NO"/>
    </ORDER>
File3.xml
<ORDER DESCRIPTION ="" ISVALID ="YES" 
        <ATTRIBUTE NAME ="Advanced" VALUE =""/>
        <ATTRIBUTE NAME ="Order type" VALUE ="NO"/>
    </ORDER>

Answer

With any awk in any shell on every UNIX box:

awk '/<ORDER/{f=1; out="file_"(++c)".xml"} f{print > out} /</ORDER>/{close(out); f=0}' file

it’s obviously fragile as it’s just doing regexp matches against text, not parsing the XML, but it’ll work for the sample you posted and any similar text.
