it seems to me that escaping is the default behaviour of print methods and also parse and sprint ones:

print ($optional_filehandle, $optional_pretty_print_style)

    Prints an entire element, including the tags, optionally to a $opt
+ional_filehandle, optionally with a $pretty_print_style.

    The print outputs XML data so base entities are escaped.
print_to_file ($filename, %options)

    Prints the element to file $filename.

    options: see flush. =item sprint ($elt, $optional_no_enclosing_tag
+)

    Return the xml string for an entire element, including the tags. I
+f the optional second argument is true then only the string inside th
+e element is returned (the start and end tag for $elt are not). The t
+ext is XML-escaped: base entities (& and < in text, & < and " in attr
+ibute values) are turned into entities.

In contrast text method specify that entities are not escaped.

Without any code and example data i cannot tell you more.
