xmlpretty - XML pretty printer

  xmlpretty [--options] [filename]

xmlpretty is the commandline interface to XML::Handler::YAWriter, acting as a tool to add and remove pretty printing to XML files.

xmlpretty has several methods to add human readablitiy.

If you want to add readablity without adding so-called ignorable whitespace, use it in the following way :

  $ xmlpretty --AddHiddenNewline \
              --AddHiddenAttrTab \
          --CatchEmptyElement \
          uglyfile.xml > prettyfile.xml

If you do not want to process the file further, but only want it human readable, add visible whitespace to the file as follows :

  $ xmlpretty --PrettyWhiteNewline \
              --PrettyWhiteIndent \
          --CatchEmptyElement \
          uglyfile.xml > prettyfile.xml

You may use YAWriter to clean whitespace from XML documents. This may work in 99% of the cases where you want to get rid of ignorable whitespace caused by the various forms of pretty printing.

  $ xmlpretty --NoWhiteSpace \
              --NoComments \
              --AddHiddenNewline \
          --AddHiddenAttrTab \
          --CatchEmptyElement \
          prettyfile.xml > cleanfile.xml

Options are given in a gnu like --option idiom.

Add hidden newline before ">"
Add hidden tabulation for attributes
Catch empty Elements, apply "/>" compression
Catch whitespace with comments
This option will cause start_document, processing_instruction and doctype_decl to appear as SGML. The SGML is still well-formed of course, if your SAX events are well-formed.
Supress Comments
Supress DTD
Supress Processing Instructions
Supress <?xml ... ?> Prolog
Supress WhiteSpace to clean documents from prior pretty printing.
Add visible indent before any eventstring
Add visible newlines before any eventstring
Output only SAX1 compilant eventstrings

Automatic recoding between 8bit and 16bit does not yet work correctly !

I have Perl-5.6 at home and here I can specify "use utf8;" in the right places to make recoding work. But I dislike saying "use 5.00555;" because many systems run 5.00503.
