This code sample generates a HTML page,with controls in it from an XML file.The XML file contains the collection of controls which u require in your page.We use an XSL to define the XML file's structure and to transform it into the required format.
The following is an example XML file named "controls.xml"
<?xml version="1.0" encoding="UTF-8" ?>
<controls>
<control type="text" name="Title" required="yes"/>
<control type="text" name="Industry"/>
<control type="label" name="Education"/>
<control type="Button" name="Test"/>
</control>
</controls>
The corresponding "controls.XSL" looks like follows(This XSL helps generate the aspx page)
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:asp="remove">
<xsl:output method="xml" indent="yes" encoding="utf-8" omit-xml-declaration="yes"/>
<xsl:template match="/">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<table cellpadding="0" cellspacing="5">
<xsl:for-each select="//question">
<tr>
<td valign="top">
<xsl:value-of select="@name" />
</td>
<td>
<xsl:if test="@type='text'">
<input id="{@name}" type="{@type}" runat="server"/>
</xsl:if>
<xsl:if test="@required = 'yes'">
<asp:RequiredFieldValidator id="reqfield" ErrorMessage="Required Field" runat="server" ControlToValidate="{@name}" />
</xsl:if>
<xsl:if test="@type='label'">
<input id="{@name}" type="{@type}" runat="server"/>
</xsl:if>
<xsl:if test="@type='Button'">
<input id="{@name}" type="{@type}" runat="server"/>
</xsl:if>
</td>
</tr>
</xsl:for-each>
</table>
<asp:button id="submit" runat="server" Text="Submit" />
</form>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
Now in your code behind, we need to write the code to transform the XML File based on XSL File
string XmlFile = Server.MapPath("controls.xml");
string XslFile = Server.MapPath("controls.xsl");
XmlDocument xdoc = new XmlDocument();
xdoc.Load(XmlFile);
XslCompiledTransform transform = new XslCompiledTransform();
transform.Load(XslFile);
XmlTextWriter writer = new XmlTextWriter(Server.MapPath("page.html"),Encoding.UTF8);
writer.Formatting = Formatting.Indented;
writer.Indentation = 4;
transform.Transform(xdoc, null, writer);
This adds a new HTML page, "page.html", to your project folder with the controls defined in your XML file.
