This plugin defines a filter for performing simple stylesheet based 
transformations of XML text.  
 
Named parameters are used to define those XML elements which require
transformation.  These may be specified with the USE directive when
the plugin is loaded and/or with the FILTER directive when the plugin
is used.
 
This example shows how the default attributes 'border="0"'and'cellpadding="4"'can be added to <table> elements.     [% USE xmlstyle 
           table = { 
               attributes = { 
                   border      = 0
                   cellpadding = 4
               }
           }
    %]    [% FILTER xmlstyle %]
    <table>
       ...
    </table>
    [% END %]
This produces the output:
     <table border="0" cellpadding="4">
       ...
    </table>
Parameters specified within the USE directive are applied automatically each
time the 'xmlstyle'FILTER is used.  Additional parameters passed to the 
FILTER directive apply for only that block.     [% USE xmlstyle 
           table = { 
               attributes = { 
                   border      = 0
                   cellpadding = 4
               }
           }
    %]    [% FILTER xmlstyle
           tr = {
               attributes = {
                   valign="top"
               }
           }
    %]
    <table>
       <tr>
         ...
       </tr>
    </table>
    [% END %]
Of course, you may prefer to define your stylesheet structures once and 
simply reference them by name.  Passing a hash reference of named parameters
is just the same as specifying the named parameters as far as the Template 
Toolkit is concerned.
     [% style_one = {
          table = { ... }
          tr    = { ... }
       }
       style_two = {
          table = { ... }
          td    = { ... }
       }
       style_three = {
          th = { ... }
          tv = { ... }
       }
    %]    [% USE xmlstyle style_one %]     [% FILTER xmlstyle style_two %]
       # style_one and style_two applied here 
    [% END %]
      
    [% FILTER xmlstyle style_three %]
       # style_one and style_three applied here 
    [% END %]
Any attributes defined within the source tags will override those specified
in the style sheet.
     [% USE xmlstyle 
           div = { attributes = { align = 'left' } } 
    %]    [% FILTER xmlstyle %]
    <div>foo</div>
    <div align="right">bar</div>
    [% END %]
The output produced is:
     <div align="left">foo</div>
    <div align="right">bar</div>
The filter can also be used to change the element from one type to another.
     [% FILTER xmlstyle 
              th = { 
                  element = 'td'
                  attributes = { bgcolor='red' }
              }
    %]
    <tr>
      <th>Heading</th>
    </tr>
    <tr>
      <td>Value</td>
    </tr>
    [% END %]
The output here is as follows.  Notice how the end tag '</th>'is
changed to'</td>'as well as the start tag.     <tr>
      <td bgcolor="red">Heading</td>
    </tr>
    <tr>
      <td>Value</td>
    </tr>
You can also define text to be added immediately before or after the 
start or end tags.  For example:
     [% FILTER xmlstyle 
              table = {
                  pre_start = '<div align="center">'
                  post_end  = '</div>'
              }
              th = { 
                  element    = 'td'
                  attributes = { bgcolor='red' }
                  post_start = '<b>'
                  pre_end    = '</b>'
              }
    %]
    <table>
    <tr>
      <th>Heading</th>
    </tr>
    <tr>
      <td>Value</td>
    </tr>
    </table>
    [% END %]
The output produced is:
     <div align="center">
    <table>
    <tr>
      <td bgcolor="red"><b>Heading</b></td>
    </tr>
    <tr>
      <td>Value</td>
    </tr>
    </table>
    </div> |
