Not able to read XML using perl -

-

i trying read xml file using perl.

i tried xml::simple , use xml::libxml, in both cases facing problems.

for xml::simple says 

"keys on reference experimental using hash reference deprecated"

when use following

foreach $k ({keys %$ref->{version}}) # output conf {     print stderr dumper($k); }

and xml::libxml, getting "can't locate xml/libxml/error.pm in @inc (you may need install xml::libxml::error module)".

when tried install libxml using activeperl ppm ui, didn't find package there. downloaded libxml other source , copied required files in "c:\perl64\lib" , "c:\perl64\site\lib".

i using perl 5, version 20. how can make work ?

your xml::simple problem misunderstanding of syntax. looks realise need use % dereference hash reference, don't realise need put expression returns hash reference in small { ... } block.

so have:

%$ref->{version}

you want:

%{$ref->{version}}

oh, , it's worse that. have { ... } around expression - you're explicitly turning expression hash reference. want is:

foreach $k (keys %{$ref->{version}})

each value in $kwill hash key. , hash keys strings. call dumper in next line unnecessary too.
