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.

table = { attributes = { border = 0 cellpadding = 4 } } [% tt_end_tag %] <table> ... </table> [% tt_start_tag %] END [% tt_end_tag %]

This produces the output: 

    <table border="0" cellpadding="4">
       ...
    </table>

Parameters specified within the USE directive are applied automatically each FILTER directive apply for only that block.

table = { attributes = { border = 0 cellpadding = 4 } } [% tt_end_tag %] tr = { attributes = { valign="top" } } [% tt_end_tag %] <table> <tr> ... </tr> </table> [% tt_start_tag %] END [% tt_end_tag %]

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. 

    [% tt_start_tag %] style_one = {
          table = { ... }
          tr    = { ... }
       }
       style_two = {
          table = { ... }
          td    = { ... }
       }
       style_three = {
          th = { ... }
          tv = { ... }
       }
    [% tt_end_tag %]
# style_one and style_two applied here [% tt_start_tag %] END [% tt_end_tag %] # style_one and style_three applied here [% tt_start_tag %] END [% tt_end_tag %]

Any attributes defined within the source tags will override those specified in the style sheet.

div = { attributes = { align = 'left' } } [% tt_end_tag %] <div>foo</div> <div align="right">bar</div> [% tt_start_tag %] END [% tt_end_tag %]

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.

th = { element = 'td' attributes = { bgcolor='red' } } [% tt_end_tag %] <tr> <th>Heading</th> </tr> <tr> <td>Value</td> </tr> [% tt_start_tag %] END [% tt_end_tag %]

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:

table = { pre_start = '<div align="center">' post_end = '</div>' } th = { element = 'td' attributes = { bgcolor='red' } post_start = '<b>' pre_end = '</b>' } [% tt_end_tag %] <table> <tr> <th>Heading</th> </tr> <tr> <td>Value</td> </tr> </table> [% tt_start_tag %] END [% tt_end_tag %]

The output produced is: 

    <div align="center">
    <table>
    <tr>
      <td bgcolor="red"><b>Heading</b></td>
    </tr>
    <tr>
      <td>Value</td>
    </tr>
    </table>
    </div>
