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>
