Re^3: HTML::Element newline character

Not the whitespace, but the newline character.

Newline is whitespace

But both as_text and as_trimmed_text cut this newline. ... Is it possible to preserve the newline?

No they don't. The whitespace is already gone before you call either of those methods. All you had to do was


$ perldoc HTML::TreeBuilder |grep -i space
        Do not represent the text content of elements. This saves spac
+e if
    $root->ignore_ignorable_whitespace(value)
        whitespace text nodes in the tree. Default is true. (In fact, 
+I'd be
    $root->no_space_compacting(value)
        This determines whether TreeBuilder compacts all whitespace st
+rings
        contiguous whitespace in the document is turned into a single 
+space.
        But that's not done if no_space_compacting is set to 1.
        Setting no_space_compacting to 1 might be useful if you want t
+o read
        Redirects to HTML::Element:: delete_ignorable_whitespace

$ perldoc HTML::Element |grep -i space
  $h->delete_ignorable_whitespace()
    whitespace. You should not use this if $h under a 'pre' element.
    "\t", or some number of spaces, if you specify it).
    whitespace is deleted, and any internal whitespace is collapsed.
    This will not remove hard spaces, unicode spaces, or any other non
+ ASCII
    white space unless you supplye the extra characters as a string
    Tabs are expanded to however many spaces it takes to get to the ne
