NAME
Template::Plugin::XML::Style - Simple XML stylesheet transfomations
SYNOPSIS
[% USE xmlstyle
table = {
attributes = {
border = 0
cellpadding = 4
cellspacing = 1
}
}
%]
[% FILTER xmlstyle %]
<table>
<tr>
<td>Foo</td> <td>Bar</td> <td>Baz</td>
</tr>
</table>
[% END %]
DESCRIPTION
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>
