Read and process RSS feed using Embed and XmlProcessor
The feedreader macro, in the Web Toolkit, allows you to read RSS and convert its data to a DataTable, which can then be formatted. It is however possible to read the xml yourself and pass it to a transform macro, or use the XmlProcessor (new in 1.3).
Here's an example of XmlProcessor processing a feed:
| Smartsite SXML |

|---|---|
<se:cache maxage="00:20" save="key = this.getcachekey()" resulttype="none" whitespace="remove">
<se:embeduri resulttype="xml" location="http://rss.cnn.com/rss/edition.rss" />
</se:cache>
<se:xmlprocessor xmldata="{cache.get(buffer.get(key))}" buildstring="true">
<se:parameters>
<se:parameter name="resultformat">
<ul>{this.result()}</ul>
</se:parameter>
<se:parameter name="actions">
<se:collection>
<se:member query="//channel/item" type="multiplenodes">
<li><a href="{this.getvalue(link)}">{this.getvalue(title)}</a></li>
</se:member>
</se:collection>
</se:parameter>
</se:parameters>
</se:xmlprocessor>
