[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Problem in making an html representation of xml docume
 I have just started learning XSLT, and was hoping that the members of this list would help me with this problem:
I would like to create an exact replica of an xml document on a web page, ie, an html page which presents the xml with original line breaks etc preserved, but with line numbers (as you'd see if you viewed the file in a text-editor such as Textpad) and additional formatting (so that I could add annotations -- images or links --next to specific elments).
I have appended my solution below, but if you use it to transform any xml document, you will see there are a few problems:
(1) word-wrap works on text-only lines, but not on lines which have a mixture of text, attribute and element nodes.
(2) I haven't yet found a way to correctly display line numbers, as they would be displayed if the xml file was viewed on a line-numbering enabled text-editor.
(3) I'd ideally like to have the whole thing displayed neatly in a table at the centre of the html page, but haven't figured out how to do this either.
Any suggestions would be extremely welcome -- I have recently started exploring XSLT, and have a feeling I'm rather out of my depth here!
Many thanks,
Munna

Breaks msg into one or more lines.
Lines are broken at the numChars-th character, so lines
will have no more than (numChars-1) characters per line.
