HTML::FillInForm rocks hard, but it neither can accept or return HTML::Tree instances, even though it works with them internally.

Therefore, those of us who operate on HTML as trees (e.g. HTML::Seamstress) have to do all the following to leverage FillinForm:

  1. convert our HTML to a string
  2. pass it fillinform
  3. get back the result and turn it back into a tree to continue processing

Now there is a fillinform method in HTML::Element::Library and here is how it's used:

first the html "template"


<html>
<head>
</head>

<body>

<form>

    <input type="text" id="age" name="age" value="balbalh" />
    <input type="text" id="email" name="email" />
    <input type="text" id="zipcode" name="zipcode" />

</form>

</body>
</html>

our Perl program



my %form = 
  (
   age => 77,
   email => 'ben@perlmon.com',
   zipcode => '29063-2134'
  );


use form_example;
my $tree = form_example->new;


# calls 
my $html = $tree->fillinform(\%form) ;

warn $html;

and the html form is filled in ...

<form>
<input value="77" name="age" type="text" id="age" /> 
<input value="ben@perlmon.com" name="email" type="text" id="email" /> 
<input value="29063-2134" name="zipcode" type="text" id="zipcode" />
</form>

Now the Perl class to treeify our HTML

[tbrannon@devel fillinform]$ spkg.pl --base_pkg=HTMLBase form_example.
+html 
comp_root........ /home/tbrannon/prg/html-element-replacer/HTML-Elemen
+t-Replacer/ex/tables/
html_file_path... /home/tbrannon/prg/html-seamstress/samples/fillinfor
+m/
html_file........ form_example.html
html_file sans... form_example
substr outside of string at /usr/bin/spkg.pl line 195.
WARNING: the comp_root and html_file_path are not equal for the extent
+ of comp_root...
This may lead to incorrect calculations at /usr/bin/spkg.pl line 197.

DONE!

have a nice day!
