I have to transform my xml output to html. I am following a tutorial at link text My code is outputting xml tags in a single line without any formatting with text value.I want the output as an HTML unordered list following hierarchical structure of parent child in xml file output.

Here is page output:

message msg 1message msg 1-1message msg 1-2message msg 1-2-1message msg 1-2-2message 
msg 1-2-2-1message msg 1-2-2-1-1message msg 1-2-2-1-2

& here is page source:

<html:ul xmlns:html="http://www.w3.org/1999/xhtml"><html:li>message msg 1</html:li>
<html:ul><html:li>message msg 1-1</html:li><html:li>message msg 1-2</html:li><html:ul>
<html:li>message msg 1-2-1</html:li><html:li>message msg 1-2-2</html:li><html:ul>
<html:li>message msg 1-2-2-1</html:li><html:ul><html:li>message msg 1-2-2-1-1</html:li>
<html:li>message msg 1-2-2-1-2</html:li></html:ul></html:ul></html:ul></html:ul></html:ul>

Here is my code

php file:

<?php
# LOAD XML FILE
$XML = new DOMDocument();
$XML->load('messages.xml');

# START XSLT
$xslt = new XSLTProcessor();
$XSL = new DOMDocument();
$XSL->load('msg.xsl');
$xslt->importStylesheet( $XSL );
print $xslt->transformToXML( $XML );
?>

msg.xsl:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    xmlns:html="http://www.w3.org/1999/xhtml">
  <xsl:output omit-xml-declaration="yes" />

  <xsl:template match="messages">
    <html:ul>
      <xsl:apply-templates select="message" />
    </html:ul>
  </xsl:template>

  <xsl:template match="message[message]">
    <html:li>message <xsl:value-of select="@msg_id" /></html:li>
    <html:ul>
      <xsl:apply-templates select="message" />
    </html:ul>
  </xsl:template>

  <xsl:template match="message">
    <html:li>message <xsl:value-of select="@msg_id" /></html:li>
    <xsl:apply-templates select="message" />
  </xsl:template>
</xsl:stylesheet>

messages.xml

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="msg.xsl"?><messages>
    <message msg_id="1" emp_msg="msg 1" parent_msg_id="" parent_msg="" depth="0">
        <message msg_id="2" emp_msg="msg 1-1" parent_msg_id="1" parent_msg="msg 1" depth="1"/>
        <message msg_id="3" emp_msg="msg 1-2" parent_msg_id="1" parent_msg="msg 1" depth="1">
            <message msg_id="4" emp_msg="msg 1-2-1" parent_msg_id="3" parent_msg="msg 1-2" depth="2"/>
            <message msg_id="5" emp_msg="msg 1-2-2" parent_msg_id="3" parent_msg="msg 1-2" depth="2">
                <message msg_id="6" emp_msg="msg 1-2-2-1" parent_msg_id="5" parent_msg="msg 1-2-2" depth="3">
                    <message msg_id="7" emp_msg="msg 1-2-2-1-1" parent_msg_id="6" parent_msg="msg 1-2-2-1" depth="4"/>
                    <message msg_id="8" emp_msg="msg 1-2-2-1-2" parent_msg_id="6" parent_msg="msg 1-2-2-1" depth="4"/>
                </message>
            </message>
        </message>
    </message>
</messages>

回答1:

Your stylesheet does not output HTML but rather an XHTML fragment, and that in a way (with qualified names) that you need to serve it as application/xml to a browser (like Mozilla, Opera, Safari, IE 9, but not IE 6-8) that understands that content type.

So make sure you do something like

  header('Content-Type: application/xml');

before sending the content to the browser. Or drop any XHTML namespace and any prefixes from the result elements, then the XSLT stylesheet outputs an HTML fragment many more browsers can parse and understand as text/html and render it as you want.

To be crossbrowser, I would use this stylesheet:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output omit-xml-declaration="yes"
                doctype-public="-//W3C//DTD HTML 4.0//EN"
                doctype-system="http://www.w3.org/TR/html4/strict.dtd"/>
    <xsl:template match="messages">
        <html>
            <body>
                <xsl:apply-templates select="*[1]"/>
            </body>
        </html>
    </xsl:template>
    <xsl:template match="message[1]">
        <ul>
            <xsl:call-template name="makeListItem"/>
        </ul>
    </xsl:template>
    <xsl:template match="message" name="makeListItem">
        <li>
            <xsl:value-of select="concat('message ',@msg_id)" />
            <xsl:apply-templates select="*[1]"/>
        </li>
        <xsl:apply-templates select="following-sibling::*[1]"/>
    </xsl:template>
</xsl:stylesheet>

Output:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<body>
<ul>
 <li>message 1
  <ul>
   <li>message 2</li>
   <li>message 3
    <ul>
     <li>message 4</li>
     <li>message 5
      <ul>
       <li>message 6
        <ul>
         <li>message 7</li>
         <li>message 8</li>
        </ul>
       </li>
      </ul>
     </li>
    </ul>
   </li>
  </ul>
 </li>
</ul>
</body>
</html>
