awk file split

Hi all,

First of all I' like to mention that I'm pretty new to unix scripting. Smilie

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
