       One of the common requirement in a healthcare application is to convert the clinical documents (which is usually stored in an XML format) into a human readable HTML format. We can use XSLT to transform XML documents into other formats (like transforming XML into HTML). XSLT stands for XSL Transformations.XSL is (eXtensible Stylesheet Language)  a styling language for XML.

    Suppose if we want to transform the following XML :view XML

Step 1: Create an XSL Style sheet with a transformation template or if the .xsl file has been provided by the business you can directly use it . View XSL

Step 2: Create a binary file rule (Rule-File-Binary) to store the XSL transformation file with .xsl extension.

Step 3: We can use OOTB function named performXSLT to convert xml to html. for calling the function create a DT and pass the XML Source and relative path to xsl file as input and in output we get the transformed content.

@performXSLT(Param.SourceData,Param.XSLPath,false)

Run the Data transform rule and trace it to find the transformed html:

Transformed HTML Output

Based on the style you specify in the XSL the transformed HTML look and feel will vary.
