How to extract text between two specific words using fread operation

I have an data file where i need to extract the text between two specific words

<Edata
Line1
Line2
Edata>

I need to Extract the text content between two specific words e.g. "<Edata" and "Edata>" using fread operation. This file will be in unknown extension file (*.kcs), so i can read only by using file operations. Any Idea..?

Read the whole thing in using fread, which I assume you know how to do. Then

word1Location = strfind(theString, '<Edata');
word2Location = strfind(theString, 'Edata>');
inBetweenText = theString(word1Location+6:word2Location-1);

I am having file like this...

<Edata
Line1
Line2
Edata>

<Edata
Line3
Line4
Edata>

I need to capture all the text between these specific words...Its not single word but number of text have to be caputured. How to do that..?

The code I gave did not work? It should work but you'll have to have the last line of code in a loop because the first two lines should return arrays with multiple starting and ending locations. Please show your code so we can debug it.

[Kanchibhotla Chandra Sekhar]

fid = fopen(OldfilePath,'r');
F = fread(fid);
s = char(F')
word1Location = strfind(s, '<Edata');
word2Location = strfind(s, 'Edata>');
inBetweenText = s(word1Location+4:word2Location-1);

This program returns the only first string but not the remaining strings

I don't think you read my last comment at all. Did you? Where is your loop? And why are you searching for <FBD when you should be searching for <Edata?

[Kanchibhotla Chandra Sekhar]

Actually i am not trying on original data files. I have taken test data files and trying this code. Sorry for that, Edata or FBD are same as i am trying on two different data files. I have not tried on loop, i know that why i not unable to get the entire array. But i tried with line by line code which doesn't work anyway.

while ischar(tline)
    /* Code */
    tline = fgets(tus8);
end

Have any idea how to do section by section. I have not tried that...

theString = fileread(OldfilePath);
parts = regexp(theString, '(?<=<Edata\s*\n).*?(?=\nEdata>)', 'match');

I took the liberty here of removing the end-of-line character after and immediately before Edata . The meaning of "between" was not well defined here: what should happen if there is other text on the same line, like

<Edata %first one
line 1
line 2
Edata>

then should the '%first one' be extracted?
