    converting text files to xml


    Please help, I have no clue where or how to start.

    I have to convert the below text file into xml and i have no clue how to.

    The description file refers to handlers like:

    FileNameNotify
    LoadButtonNotify
    ImageMagnificationNotify
    ColorApplyButtonNotify
    ColorResetButtonNotify
    QuitButtonNotify

    You can represent these simply by a function/method taking no
    parameters
    but printing out its own name to standard output when called.

    Re: converting text files to xml

    Basically, you want to split the text file into smaller and smaller chunks
    using string methods, and then map the contents at each level to XML tags.
    For example, the content within each set of parentheses appears to describe
    a set of controls, so you might start by outputing a <controls> element to
    contain all the controls. Next, read the content up to the first opening
    parenthesis, and write a <control> tag.

    The content within each set of parentheses consists of items delimited by
    line terminators. Each line is a name/value pair. It looks like those are
    separated by tabs, but I can't tell from your example. At any rate, the
    process would be, read the line, extract the name and use that as the XML
    element name, write the opening tag, extract the value, write that and then
    close the tag. Repeat that until you encounter the closing parenthesis that
    marks the end of each control. When you find that close the <control> tag.
    <controls>
    <control>
    <type>:text-field</type>
    <name>DirectoryPathField</name>
    <owner>ControlArea</owner>
    <x>5</x>
    <y>5</y>
    etc.
    </control>

    repeat to end of file.

    </controls>
