Oracle Integration Cloud (OIC) supports using XSLT (Extensible Stylesheet Language Transformations) for transforming XML documents. XSLT is a powerful language for converting one XML document into another or into other formats, such as HTML or plain text. In OIC, you can use XSLT to perform XML-to-XML transformations within your integration flows. Here’s how you can use XSLT in Oracle Integration Cloud:

1. Create an Integration Flow:
1. Log in to your Oracle Integration Cloud instance and create a new integration or open an existing one where you want to apply an XSLT transformation.
2. Add an XSLT Mapper Activity:
1. Within your integration flow, add an “XSLT Mapper” activity. This activity is specifically designed for XSLT transformations.
3. Configure the XSLT Mapper Activity:
1. In the XSLT Mapper activity, configure the source XML and XSLT stylesheet. The source XML is the XML document you want to transform, and the XSLT stylesheet is the transformation logic written in XSLT.
4. Write the XSLT Transformation:
1. In the XSLT stylesheet, you define rules for how the input XML should be transformed into the desired output XML. XSLT uses a declarative syntax to specify these transformation rules.
