I Need a Human Readable, Yet Parse-able Document Format

问题

I'm working on one of those projects where there are a million better ways to accomplish what I need but I have no choice and I have to do it this way. Here it is:

There is a web form, when the user fills it out and hits a submit a human readable text file is created using the form data. It looks like this:

field_1: value for field one

field_2: value for field two
more data for field two (field two has a newline in it!)

field3: some more data

My problem is this: I need to parse this text file back into the web form so that the user can edit it.

How could I, in a foolproof way, accomplish this? A database is not an option, I have to use these text files.

My Questions:

Is there a foolproof way to do this using the format in the example above?
What human readable format would work better (in other words I can change the format)
Human readable means that a non programmer could read it and know what is what.

This project uses PHP.

UPDATE

By human readable I mean that anyone could read the text and not be overwhelmed by it, including your grandmother.

This is what YAML was designed to be. You can read more about it on their site or on Wikipedia.

To quote Wikipedia:

YAML syntax was designed to be easily mapped to data types common to most high-level languages: list, hash, and scalar. Its familiar indented outline and lean appearance makes it especially suited for tasks where humans are likely to view or edit data structures, such as configuration files, dumping during debugging, and document headers

The advantage over XML is that it doesn't use tags which might confuse users. And I think it's cleaner than INI (which was also mentioned) because it simply uses colons instead of equals signs, semicolons and quotes.

Sample YAML looks like:

invoice: 34843
date   : 2001-01-23
bill-to: &id001
    given  : Chris
    family : Dumars
    address:
        lines: |

    - sku         : BL4438H
      quantity    : 1
      description : Super Hoop
      price       : 2392.00

I'd say either use

INI files or
YAML or
Markdown or
Textile

or just about any lightweight markup language you deem appropriate.

回答3:

You might want to look into YAML

I agree with Pablo Fernandez response. I think JSON might be a good choice as well.

回答4:

XML is an option.

I'm just gonna say that an INI string is pretty readable:

Pet_Name = "Fred"

But, you could always roll your own format. Something like:

Key: ValueValueValueValueValueValue
Key: ValueValue

Basically, you would explode the string by newlines, look for text strings infront of colons and use that as the key, and the data after the colon and before the newline is the value.
