convert Vector to xml

[peter brews]

Input will be vector whose each element will itself be a vector.Length of vector of each element may vary for different calls.Only the selected element needs to be placed in proper order in the output.For ex. field2 is not required in the output.Also field4 is placed before field3.Below is the code that I tried to write.Can any one help me with better solution.

The Input is vector :
"[ [field1,f1_val1,f1_val2,f1_val3,f1_val4] ,[field2,f2_val1,f2_val2,f2_val3,f2_val4],
,[field3,f3_val1,f3_val2,f3_val3,f3_val4,f3_val5],
,[field4,f4_val1,f4_val2]] )

Expected output is :
< FIELD Row=1>
<field1>f1_val</field1>
<field4>f2_val1</filed4>
<field3>f3_val1</field3>
</FIELD>
< FIELD Row=2>
<field1>f1_va2</field1>
<field4>f2_val2</filed4>
<field3>f3_val2</field3>
</FIELD>
< FIELD Row=3>
<field1>f1_va3</field1>
<field3>f3_val3</field3>
</FIELD>
< FIELD Row=4>
<field1>f1_val4</field1>
<field3>f3_val4</field3>
</FIELD>
< FIELD Row=5>
<field3>f3_val5</field3>
</FIELD>
