Search the word to be deleted and delete lines above this word starting from P1 to P3

Hi,
I have to search a word in a text file and then I have to delete lines above from the word searched . For eg suppose the file is like this:

Records
Code:
P1
10,23423432
,77:1
,234:2
P2
10,9089004
,77:1
,234:2
,87:123
,9898:2
P3
456456
P1
:123,456456546
P2
abc:324234
,89237494
P3
,98:234
.
.
.

and so on.

The file contains thousands of records.

Now I have to search for a particular word for eg I am searching 9089004. Then the records in which 9089004 will lie I mean from P1 till P3 will be deleted from the file and rest of the records will exist in the file. The problem is that the word can exist anywhere between P1 to P2 or from P2 to P3 and then I have to delete that record i.e. from P1 to P3.

Please help

NAME
glSampleMaski - set the value of a sub-word of the sample mask C SPECIFICATION
void glSampleMaski(GLuint maskNumber, GLbitfield mask); PARAMETERS
maskNumber Specifies which 32-bit sub-word of the sample mask to update. mask Specifies the new value of the mask sub-word. DESCRIPTION
glSampleMaski sets one 32-bit sub-word of the multi-word sample mask, GL_SAMPLE_MASK_VALUE. maskIndex specifies which 32-bit sub-word of the sample mask to update, and mask specifies the new value to use for that sub-word. maskIndex must be less than the value of GL_MAX_SAMPLE_MASK_WORDS. Bit B of mask word M corresponds to sample 32 x M + B. NOTES
glSampleMaski is available only if the GL version is 3.2 or greater, or if the ARB_texture_multisample extension is supported. ERRORS
GL_INVALID_VALUE is generated if maskIndex is greater than or equal to the value of GL_MAX_SAMPLE_MASK_WORDS. SEE ALSO
