Transformation Programming Languages
You can use PeopleCode or Extensible Stylesheet Language Transformation (XSLT) as programming languages for creating transformation logic.
XSLT is a well-recognized standard language perfectly suited to manipulating XML structures, so it’s highly recommended for transformations. Because of its straightforward template-based approach to accessing the codeset repository, XSLT is also recommended for data translation.
Note: When programming using XSLT, you can hand-code the XSLT or use the Oracle XSL Mapper to graphically associate records and fields. The Oracle XSL Mapper then automatically generates the XSLT code.
However, you cannot use XSLT to filter messages based on content, so filtering must be implemented in PeopleCode.
Note: Filtering must be implemented using PeopleCode
You can use both XSLT and PeopleCode steps in a single transform program.
Each XSLT program must be enclosed in the following wrapper:
Note: When using Oracle XSL Mapper, the mapper automatically encloses the program in this wrapper.
<?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> your_xslt_program </xsl:stylesheet>
Third-party XSLT development tools may generate a wrapper that specifies a different URI. Make sure the URI in your program is exactly as shown here, or your program may not work as expected.
You can find more information about XSLT at the World Wide Web Consortium (W3C) web site.
