ASP.NET WebForms + XSLT Transformation
Workflow
- The C# backend fetches XML string (student data) from the database
- Load the XML string into
MemoryStreamand create anXPathDocument - Read the
student.xslstylesheet from the physical path within the project - Perform XSLT transformation with
XslCompiledTransformto output an HTML string - Pass the generated HTML to the frontend page for rendering (you can implement this yourself. XSL is not limited to web scenarios; it can also serve as a template engine)
Prepare your full‑format XML on your own
student.xsl File
Place this file inside your project
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<!-- Set output to HTML with UTF‑8 encoding to fix Chinese garbled characters -->
<xsl:output method="html" encoding="UTF-8" indent="yes"/>
<xsl:template match="/">
<html>
<head>
<meta charset="UTF-8"/>
<title>Student List</title>
</head>
<body>
<ul>
<!-- Path matches XML structure: Root → StudentDB → Student -->
<xsl:for-each select="StudentDB/Student">
<li>
No:<xsl:value-of select="position()"/>
Name:<xsl:value-of select="Name"/>
</li>
</xsl:for-each>
</ul>
</body>
</html>
</xsl:template>
</xsl:stylesheet>Code language: HTML, XML (xml)
