I don't think AttrIndent does what you expect.
XML::Simple:
AttrIndent => 1 # out - handy
When you are using XMLout(), enable this option to have attributes printed one-per-line with sensible indentation rather than all on one line.
Update 1: Args to XMLout is a list, not a hash, as pointed out by Anonymous Monk.

Update 2: Using use XML::Simple qw(:strict); would have given a warning:

No value specified for 'ForceArray' option in call to XMLin()

use strict;
use warnings;
use XML::Simple;

my $str = <<EOL;
<opt class="java.beans.XMLDecoder" version="1.6.0-oem">
  <object class="java.util.HashSet">
    <void method="add" string="baseball" />
    <void method="add" string="football" />
  </object>
</opt>
EOL

my $ref = XMLin($str);
open FH, ">", "webcams.xml" or die ("open failed");
print FH XMLout($ref, 
  AttrIndent => 1,
  xmldecl => '<?xml version="1.0" encoding="UTF-8"?>');
close FH or die ("close failed");
__END__
<?xml version="1.0" encoding="UTF-8"?>
<opt class="java.beans.XMLDecoder"
     version="1.6.0-oem">
  <object class="java.util.HashSet">
    <void method="add"
          string="baseball" />
    <void method="add"
          string="football" />
  </object>

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.


No such thing as a small change
