[REBOL] Recursive-Read question
From: bry::itnisk::com at: 5-Nov-2002 13:49
Hi, I have a question about the Recursive-Read function, which is
provided in http://www.reboltech.com/library/html/Recursive Read.html
Now of course what it does is not to Recursively Read a directory but
rather read a file or Url into a block and then recursively read that
block.
The problem there is that if I want to get something hierarchical out of
it, I can't.
As an example of what I mean I have the following:
xml-dec: rejoin["<?xml version='1.0' encoding='ISO-8859-1'?><files>"]
write %dir.xml xml-dec
sep: "/"
ReadDir-ToXml: function [
"Based on Andrew Martin's Recursive-Read."
Directory [file! url!]] [Files Subdirectory] [
Files: read Directory
if block? Files [
foreach File Files [
if directory? File [
path: replace/all Directory/:Subdirectory/:File "none/" ""
path: replace/all path Subdirectory ""
write/append %dir.xml rejoin["<folder name='" File"' path='" path "'
modified='" modified? File "' size='" size? File "'>"]
Subdirectory: File
foreach File read Directory/:Subdirectory [
name: to-string File
either find name sep[
append Files Subdirectory/:File
][
write/append %dir.xml reduce[ "<file name='" File "' path='"
Directory/:Subdirectory/:File "' modified='" modified?
File "' size='" size? File "'/>"]
]
]
write/append %dir.xml "</folder>"
]
]
]
write/append %dir.xml rejoin["</files>"]
]
So anyway I was hoping to get some help on this, things I'd like help
with are 1. since I'm still in the beginner phase with Rebol and just
taking scripts like this for reuse, what are some most evident things I
could do to include the coding of ReadDir-ToXml now that I muddied it
all up?
2. Is there a simple way to make it hierarchical? If not it doesn't
matter as I could write an xslt that reprocessed it no problem.
