( [id://3333]=superdoc: print w/replies, xml ) Need Help??
Hi, I have a problem in reading an XML file that I want to include in a __DATA__ section. My first try was using the XML in the __DATA__ section as follows: my $cr = XMLin( *DATA ); After reading the XML::Simple docs, I saw it required an IO::Handle object, so I tried this:
my $xmldata = IO::Handle->new->fdopen(fileno(DATA),'r'); # print $xmldata->getline(); my $cr = XMLin( $xmldata );
which results in the error:

Unable to recognise encoding of this document at /usr/local/lib/perl5/site_perl/5.8.7/XML/SAX/PurePerl/EncodingDetect.pm line 96. Document requires an element Ln: 1, Col: 0

Which leads me to believe the $xmldata IO::Handle doesn't return any lines, however, If I uncomment the getline() line from the code above it prints a line, starting at character 12199 of my XML file.

I got 2 questions about this:

How can I read an XML file from a __DATA__ section (preferably with XML::Simple) ?

What magic happens with the DATA filehandle? Is some predefined number of characters read in from it at compilation time?

UPDATE: never mind question number 1, this solves my problem:

my $cr = XMLin( do { local $/ ; <DATA> } );
I'm still interested in what happend though.

  • 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).
