# Example: lr_xml_transform

The following example transforms an XML string, xml_input, using the XSL specification, stylesheet, and saves the transformation into the parameter, Result.

Both xml_input and stylesheet are char strings and are converted to parameter format using lr_save_string. After lr_xml_transform is invoked, the output parameter which contains the formatted data, Result, is evaluated using lr_eval_string.

    #include "as_web.h"

    char *xml_input =
    "<?xml version=\"1.0\" ?>"
         "<sales>"
              "<summary>"
                   "<heading>Acme Organization</heading>"
                   "<subhead>IT Management Report</subhead>"
                   "<description>Report by Department</description>"
              "</summary>"
         "</sales>";

    char *stylesheet =
    "<?xml version=\"1.0\"?>"
    "<xsl:stylesheet xmlns:xsl=\"http://www.w3.org/1999/XSL/Transform\" version=\"1.0\">"
    "<xsl:output method=\"html\"/>"
    "<xsl:template match=\"/\">"
         "<HTML>"
              "<HEAD>"
                   "<TITLE><xsl:value-of select=\"//summary/heading\"/></TITLE>"
              "</HEAD>"
              "<BODY>"
                   "<h1><xsl:value-of select=\"//summary/heading\"/></h1>"
                   "<h2><xsl:value-of select=\"//summary/subhead\"/></h2>"
                   "<p><xsl:value-of select=\"//summary/description\"/></p>"
              "</BODY>"
         "</HTML>"
    "</xsl:template>"
    "</xsl:stylesheet>";

    Action() {

         lr_save_string(xml_input, "XML_Input_Param"); // Save to a parameter
         lr_save_string(stylesheet, "XML_StyleSheet_Param");// Save to a parameter

         lr_xml_transform("XML={XML_Input_Param}", "ResultParam=Result",
              "Stylesheet={XML_StyleSheet_Param}", LAST );

         lr_output_message(lr_eval_string("String after transformation: {Result}"));

         return 0;
    }

Example: Output:
Action.c(39): String after transformation: <HTML>
<HEAD>
<TITLE>Acme Organization</TITLE>
</HEAD>
<BODY>
<h1>Acme Organization</h1>
<h2>IT Management Report</h2>
<p>Report by Department.</p>
</BODY>
</HTML>
