I am pasting bigger sample of my data file (2.txt), original file runs into 5MB data.
Code:
~b "ST_ah_2_2"
<FIRST> 
 6.42 2.53
<SECOND> 2
 1.8 6.29
~b "ST_ah_3_6"
<FIRST> 2
 6.61 1.02
<SECOND> 2
 1.51 6.33
~b "ST_ah_4_9"
<FIRST> 2
 6.33 1.02
<SECOND> 2
 2.61 2.42
~b "ST_ih_2_2"
<FIRST> 2
 6.66 1.01
<SECOND> 2
 2.01 1.08
~b "ST_ih_3_3"
<FIRST> 2
 6.63 1.20
<SECOND> 2
 2.29 1.02
 ~b "ST_ih_4_4"
<FIRST> 2
 6.87 9.01
<SECOND> 2
 3.45 4.06
~b "ST_er_2_5"
<FIRST> 2
 6.89 1.20
<SECOND> 2
 2.16 4.22
~b "ST_er_3_5"
<FIRST> 2
 6.01 9.20
<SECOND> 2
 6.16 4.22
 ~b "ST_er_4_5"
<FIRST> 2
 6.89 1.20
<SECOND> 2
 6.36 2.42
~a "aa-ah"
<BEGIN>
<STATES> 3
<STATE> 1
~b "ST_ah_2_2"
<STATE> 2
~b "ST_ah_3_6"
<STATE> 3
~b "ST_ah_4_9"
~z "Z_ah"
<END>
~a "iy-ih"
<BEGIN>
<STATES> 3
<STATE> 1
~b "ST_ih_2_2"
<STATE> 2
~b "ST_ih_3_3"
<STATE> 3
~b "ST_ih_4_4"
~z "Z_ih"
<END>
~a "ey+er"
<BEGIN>
<STATES> 3
<STATE> 1
~b "ST_er_2_5"
<STATE> 2
~b "ST_er_3_5"
<STATE> 3
~b "ST_er_4_5"
~z "Z_er"
<END>

If my 1.txt happened to be like this:
Code:
2 s1 ey+er
1 s2 ey+er
1 s3 ey+er
1 s1 iy-ih
1 s2 iy-ih
2 s3 iy-ih

I am expecting output as;
Code:

6.89 1.20 2.16 4.22 6.89 1.20 2.16 4.22 6.01 9.20 6.16 4.22 6.89 1.20 6.36 2.42 6.66 1.01 2.01 1.08 6.63 1.20 2.29 1.02 6.87 9.01 3.45 4.06 6.87 9.01 3.45 4.06

Output could be understood as;
1. Read 1.txt. Line 1 is 2 s1 ey+er i.e; 2 times <STATE> 1 of label ey+er in 2.txt.
2. Search "ey+er" (unique and not pattern as there might be labels like "ey+er+t" etc.) in 2.txt. Go to tag <STATE> 1. Then Combine elements of <FIRST> and <SECOND> tag i.e 6.89 1.20 2.16 4.22. After this, as column 1 in 1.txt was 2, so write this 2 times in a file i.e;
Code:
6.89 1.20 2.16 4.22 6.89 1.20 2.16 4.22

3. Again read 2nd line of 1.txt i.e. 1 s2 ey+er.
4. Search <STATE> 2 (i.e s2) of label ey+er in 2.txt. Combine elements of <FIRST> and <SECOND> tag i.e.
Code:
6.01 9.20 6.16 4.22

. As column 1 of 1.txt has element 1, so only one time I append this in new text file.
Now the combined output is :
Code:
6.89 1.20 2.16 4.22 6.89 1.20 2.16 4.22 6.01 9.20 6.16 4.22

I need to repeat this process till 1.txt finishes.
