in reply to XML::Simple attribute indentation not working

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> </opt>
