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

NAME
hwloc-assembler - Assemble multiple XML topologies SYNOPSIS
hwloc-assembler [options] output.xml [--name <name1>] input1.xml [--name <name2>] input2.xml ... OPTIONS
-n --name <name> Set <name> in the AssemblerName info attribute of the next input topology root to ease identification within the final global topol- ogy. -f --force Ignore errors while reading input files. -v --verbose Verbose messages. DESCRIPTION
hwloc-assembler combines the input XML topologies and exports the resulting global topologies to a new XML file. All inputs are inserting as children of the global root object. Each input topology root is annotated with info attributes before insertion. AssemblerIndex is set to the index within the list of inputs. AssemblerName is set to the name given with --name if any. hwloc-assembler-remote offers a fron- tend for assembling remote nodes topologies without having to manually gather and transfer each of them. EXAMPLES
To assemble two nodes topologies: $ hwloc-assembler output.xml --name host1 host1.xml --name host2 host2.xml RETURN VALUE
Upon successful execution, hwloc-assembler returns 0. hwloc-assembler will return nonzero if any kind of error occurs, such as (but not limited to) failure to parse the command line. SEE ALSO
