Xml Control

Definition and Usage

The XML control is used to display an XML document or the results of an XSL Transform.

Note: At least one of the XML Document properties must be set or no XML document is displayed.

You can also specify an XSLT document that will format the XML document before it is written to the output. You can format the XML document with the Transform property or the TransformSource property.

Properties

Property	Description
Document	Specifies an XML document using a System.Xml.XmlDocument object
DocumentContent	Specifies an XML string
DocumentSource	Specifies a path to an XML file to display
id	A unique id for the control
runat	Specifies that the control is a server control. Must be set to "server"
Transform	Formats the XML document using a System.Xml.Xsl.XslTransform object
TransformSource	Specifies a path to an XSL Transform file

Example 1

The following shows a sample XML file called "cdcatalog.xml":

<?xml version="1.0" encoding="ISO-8859-1"?>
<catalog>
  <cd>
    <title>Empire Burlesque</title>
    <artist>Bob Dylan</artist>
    <country>USA</country>
    <company>Columbia</company>
    <price>10.90</price>
    <year>1985</year>
  </cd>
  <cd>
    <title>Hide your heart</title>
    <artist>Bonnie Tyler</artist>
    <country>UK</country>
    <company>CBS Records</company>
    <price>9.90</price>
    <year>1988</year>
  </cd>
  <cd>
    <title>Greatest Hits</title>
    <artist>Dolly Parton</artist>
    <country>USA</country>
    <company>RCA</company>
    <price>9.90</price>
    <year>1982</year>
  </cd>
  <cd>
    <title>Still got the blues</title>
    <artist>Gary Moore</artist>
    <country>UK</country>
    <company>Virgin records</company>
    <price>10.20</price>
    <year>1990</year>
  </cd>
  <cd>
    <title>Eros</title>
    <artist>Eros Ramazzotti</artist>
    <country>EU</country>
    <company>BMG</company>
    <price>9.90</price>
    <year>1997</year>
  </cd>
</catalog>

The following shows a sample XSLT file called "cdcatalog.xsl":

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="/">
  <html>
  <body>
  <h2>My CD Collection</h2>
  <table border="1">
    <tr bgcolor="#9acd32">
      <th align="left">Title</th>
      <th align="left">Artist</th>
    </tr>
    <xsl:for-each select="catalog/cd">
    <tr>
      <td><xsl:value-of select="title"/></td>
      <td><xsl:value-of select="artist"/></td>
    </tr>
    </xsl:for-each>
  </table>
  </body>
  </html>
</xsl:template>

</xsl:stylesheet>

The following example shows how to use the Xml control to display the sample XML file using the sample XSLT file:

<html>
<body>
  <form runat="server">
  <asp:Xml id="cd" DocumentSource="cdcatalog.xml"
  TransformSource="cdcatalog.xsl" runat="server"/>
  </form>
</body>
</html>
