Finding best way to pretty print XML files

Havn't found best soultion to pretty print XML:

REXML: It has pp functionality, but it wrap elements like <a>content</a>

Nokogiri: there is a approch to pp, see ex:

# Pretty print XML
require "nokogiri"

def write(buffer)

  xsl =<<XSL
<xsl:stylesheet version="1.0"
  <xsl:output method="xml" encoding="UTF-8" indent="yes"/>

<xsl:strip-space elements="*"/>
<xsl:template match="/">
  <xsl:copy-of select="."/>


    doc = Nokogiri::XML(buffer)
    xslt = Nokogiri::XSLT(xsl)
    out =  xslt.transform(doc)

But nokogiri has another problem, which unwrap CDATA.

Any better solution? Thanks. And apologize for my poor english.

Sorry if you haven't got any help,

could you provide more informations to the output you want ?

There are many ways to indent XML code. Maybe you don't want to wrap lines
with <a>content</a>, but what if the content is longer ? Do you have a
column limit ?

In your place, I would take the pp code of nokogiri and tweak it until it
gives me what I want.

Hope that help,

In my experience, everyone has a different definition of "pretty printing".
If you want to get more specific about what you'd like to see, perhaps
people can give you a more specific answer.

PDF File -- Security lock
I was looking at a PDF file that was just a companies reproduction of a product label -- a herbcide, for what its worth. These labels are mostly long strings of boilerplate language with safety precautions for use, etc. that can go on for pages upon pages and are pretty much the same for each herbcide. There are usually then one or two pages that deal specifically with the herbicide itself. So, rather than print off all the pages, I went to copy and paste the relevant page and found that while I was allowed to print the relevant document, copy function was disabled. There was a little gold...

Hello all. I am writing some stuff out to a word document using standard printing commands (fprintf) to a file ___.doc. When I open the file in Word, it asks me for the encoding to use.

The best way to bin data to a grid? (may not be an IDL-specific question)
Hi all, I have some satellite data I'd like to bin to a high-resolution 2D grid for plotting and/or other analytical purposes. Each data point that I have has a corresponding latitude and longitude of the centre of the original pixel that the data was originally recorded from. The grid I'm trying to assign this data to is of a much finer resolution than what the data was taken from, so several data points may be assigned to the same pixel, in which case I guess an average data value will need to be assigned instead. To further complicate matters, the data I want to bin is a global dat...
