Skip to main content

Developing in Cascade how to

Output content as JSON

With a combination of Template, Format, and Output, you can publish page content as a JSON file.

Template

Create a Template using skip tags and a "dummy" surrounding element:

HTML 
<!--#cascade-skip--><pass-through><system-region name="DEFAULT"/></pass-through>

Format

Generate valid JSON and surround it with a #protect-top code section. In Velocity, SerializerTool.toJson converts an XML string or JDOM Element to JSON.

Velocity 
#set ($callingPage = $_XPathTool.selectSingleNode($contentRoot, "//calling-page/system-page"))
<!--#protect-top
$_SerializerTool.toJson($callingPage, true)
#protect-top-->

Or in XSLT:

XML 
<xsl:comment>#protect-top
...JSON content here...
#protect-top</xsl:comment>

Output

Create a new Output in your page Configuration:

  • Type of Data — JSON
  • File Extension — .json
  • Template — the Template you created above
  • Regions — apply the Format you created and a calling page Index Block to the DEFAULT region
