Would this help you ?

Code:
$ cat file
<RECORD>
<element1>11</element1>
<element2>22</element2>
<element3>33</element3>
<element4>a</element4>
<element5>b</element5>
<element6>c</element6>
</RECORD>
<RECORD>
<element1>44</element1>
<element2>55</element2>
<element3>66</element3>
<element4>a</element4>
<element5>b</element5>
<element6>c</element6>
</RECORD>

Code:
awk  '
      /<.*>/ && NF==3{
                        s = 1; p = $0
                        next
                     }
                    s{
		        i = 0
                        p = p RS $0 
                        f = $3
		    while(1)
		      {
                         getline 
			 if(++i < tags)
                         	p = p RS $0
		         if(i < fname) 
                       	 	f = f $3
			 if(/<\/.*>/ && NF==3)break
                      }
			 s = 0
			 f = f".xml"
			 print p RS $0 > f
			 close(f)
                     }
    
      ' tags="3" fname="2" FS='[>|<]' file

Code:
$ cat 1122.xml 
<RECORD>
<element1>11</element1>
<element2>22</element2>
<element3>33</element3>
</RECORD>

$ cat 4455.xml 
<RECORD>
<element1>44</element1>
<element2>55</element2>
<element3>66</element3>
</RECORD>

change these variablestags="4" fname="3"

Example :

when tags="4" and fname="3"
then
Code:
$ cat 112233.xml 
<RECORD>
<element1>11</element1>
<element2>22</element2>
<element3>33</element3>
<element4>a</element4>
</RECORD>

$ cat 445566.xml 
<RECORD>
<element1>44</element1>
<element2>55</element2>
<element3>66</element3>
<element4>a</element4>
</RECORD>

RavinderSingh13, Works for the example but not in general. As stated at the beginning, there will be very large xml files where the input of element1 and element2 are unknown and their combination unique.
Therefore, I am trying to read these values in order to put them in the filename of each file created.Smilie

Try this if you don't want to print main tag

Code:
awk  '
      /<.*>/ && NF==3{
                        s = 1
                        next
                     }
                    s{
		         i = 0
                         p = $0 
                         f = $3
		    while(1)
		      {
                         getline 
			 if(++i < tags)
                         	p = p RS $0
		         if(i < fname) 
                       	 	f = f $3
			 if(/<\/.*>/ && NF==3)break
                      }
			 s = 0
			 f = f".xml"
			 print p > f
			 close(f)
                     }
    
      ' tags="3" fname="2" FS='[>|<]' file

hello Akshay Hegde, first of all thanks for the help and sorry for the late reply.
I've tried and tried to figure it out, however the produced output is not the one I would like.

I think I expressed myself clearly

The dimensions of the xml are not defined, the only certainties are:
i)split nodes:
Code:
<XML>
<RECORD>
<ISTITUTO>01 </ISTITUTO>
<CODE>01</>
.
.
.
</RECORD>
<RECORD>
<ISTITUTO>02 </ISTITUTO>
<CODE>02</>
.
.
.
</RECORD>
..........
.........
</XML>

While the final desired output


Code:
0101.xml

<XML>
<RECORD>
<ISTITUTO>01 </ISTITUTO>
<CODE>01</>
.
.
.
</RECORD>
</XML>


file : 0102.xml

<XML>
<RECORD>
<ISTITUTO>01 </ISTITUTO>
<CODE>02</>
.
.
.
</RECORD>
..........
.........
</XML>


Sorry for the inconvenience.

I'm trying to split an large xml with awk and rename it based on the values of two attributes.
Example XML
Code:
<RECORD>
<element1>11</element1>
<element2>22</element2>
<element3>33</element3>
<element4>a</element4>
<element5>b</element5>
<element6>c</element6>
</RECORD>
<RECORD>
<element1>44</element1>
<element2>55</element2>
<element3>66</element3>
<element4>a</element4>
<element5>b</element5>
<element6>c</element6>
</RECORD>

The desired output would be :

Code:
a file named 1122.xml
<RECORD>
<element1>11</element1>
<element2>22</element2>
<element3>33</element3>
</RECORD>

a file named 4455.xml
<RECORD>
<element1>44</element1>
<element2>55</element2>
<element3>66</element3>
</RECORD>

Up till know I have been able to split the file using this command
Code:
awk '/<RECORD/{close("row"count".xml");count++}count{f="row"count".xml";print $0 > f}' file.xml

but couldn't figure how to pass the values of the elements 1 & 2 in the filename. Ideally I would like to add xml tags as this is intended to split xml files and produce valid xml format output.

Any ideas on how to do it with awk ?
Thank you in advance.

PS. I know that it has been addressed in a couple of posts, such as shell-210529-xml-split-extract-string-between-chars.html
though I could use the proposed solution, it always produce me only one file with the final record.Smilie

again, thanks
