Hello,

I want to open a text file, and identify a string. The text file can have multiple lines. For instance I want to find the term "AX" wherever it is on the text file and then do something according to the next chars (AX=1 does something different from AX=2). Any help appreciated,

regards, Hugo

Thanks for replying. Do you know can I move through columns in a text file? I know I shall use a for cycle, but I don't know how to do it.

Hi,

The file is a programming file, with several lines. Every line has at least a char. I want to identify the string AX (for instance), then according to its value I want to assign a value to a variable, let´s say "var1" so, as an example, -if It finds AX equal to 2, it assigns a value to the variable var1, lets say 1, and if it finds AX equal to 5, it assigns the value 2

How can I do that? The line where AX appears can vary.

Thanks for replying regards, Hugo

在 MATLAB Online 中打开

But do you have a content that looks like this:

 ID=1, AX=28.3, BX=17, STRID="Oregon"
 ID=2, AX=24.7, BX=9, STRID="Michigan"

which has a regular structure, or is it more like that:

 var n = doc.createElement("input"); n.type = "hidden"; n.name = "c[AX=28.1]"; newElem.value = "contest"; doc.forms['search', AX=25.7].appendChild(n2); select = 8;

which has no regular structure?
