Pick the exact value

Hi,

How do i pick a particular value from a group of lines using python.

for instance from the below sample. How do I pick Value=1 of OuterLines=1 and InnerLine=1
Quote:
OuterLines=1
InnerLine=1
Value=1
InnerLine=2
value=2
InnerLine=3
value=3
OuterLines=2
InnerLine=1
value=1
InnerLine=2
value=2
InnerLine=3
value=3

show what you have next time.
Code:
#!/usr/bin/python
f=open("file")
for line in f:
    if line.startswith("OuterLines=1"):
        if f.next().startswith("InnerLine=1"):
            print f.next()
f.close()

But there could be multiple lines after the Innerline=1, In the below data i need all 6 value=1 lines

Quote:
OuterLines=1
InnerLine=1
Value=1
Value=1
Value=1
Value=1
Value=1
Value=1
InnerLine=2
value=2
InnerLine=3
value=3
OuterLines=2
InnerLine=1
value=1
InnerLine=2
value=2
InnerLine=3
value=3

    if line.startswith("OuterLines=1"):
        if f.next().startswith("InnerLine=1"):
            while 1:
                N=f.next().strip()
                if N.startswith("InnerLine=2"): 
                    break
                print N

then you make it break when the value is not "Value=1". otherwise, you have to provide a more concrete example of your sample data. I followed what is provided by you.

Below mentioned is the sample data. I would have the value of JS name( that is XXX of the first tag) and J name values ( that is X_NAME1 of the first tag). Using which i should find all the "C f" values

Thanks
