Using PHP and XSL-T for Links

[Dr Livingston]

Hello, I need to pass a set of dynamic links using PHP and XSL-T from XML. Can anyone help?

XML File:

<?xml version='1.0' ?>
<root>
    <tab-title>
        <bold>Manage Employee's</bold>
    </tab-title>
    <tab-message>You may use the Quick Search below to administer an employee.</tab-message>
    <tab-spacer />
    <tab-content>
        [ 
        <link href='index.php?Do=UserSearch&chr=A'>A</link> |
        <link href='index.php?Do=UserSearch&chr=B'>B</link> |

...

<link href='index.php?Do=UserSearch&chr=Z'>Z</link> |
        ]
    </tab-content>
</root>

And now the XSL File:

<!-- ANCHORs -->

<xsl:template match = "link">
     <a>
      <xsl:attribute name="href">
        <xsl:value-of select = "@href"/>
    </xsl:attribute>
      <xsl:value-of select="."/>
    </a>
</xsl:template> 

The problem seams to be this part ?Do=UserSearch&=A

I know this problem with entities has been solved before, though for the life of me, I cannot find it on the Net.

Any help, as always, is welcome and well recieved.

What is the exact problem? Is the query string not passing through or are you getting a "XML not well-formed error?

By the way, it's XSLT, no hyphen.

[Dr Livingston]

I assume it is the &amp that is the cause of the problem. Here is the error I get:

Warning: Sablotron error on line 10: XML parser error 4: not well-formed (invalid token) in D:\Program Files\Apache Group\Apache\htdocs\rootUser3\admin\secure\classes.php on line 896
Error:XML parser error 4: not well-formed (invalid token)

I took a look at the XSL list archives and you'll need to substitute & with

&

While the parser won't translate this into an ampersand on it's own, your browser should.

Another option may be stitching the query string together with something like(not tested, high likelihood of errors but you should get the idea:

XML:
<link href='index.php?Do=UserSearch'>
<query>
chr=Z
</query>
Z
</link>

XSL:
<xsl:template match = "link">

     <a>

      <xsl:attribute name="href">

        <xsl:value-of select = "@href"/>
         <xsl:apply-templates />

    </xsl:attribute>

      <xsl:value-of select="."/>

    </a>

</xsl:template>
<xsl:template match = "query">
          <xsl:text>&</xsl:test>
        <xsl:value-of select = ".'/>
</xsl:template>

but that may be totally off.

Thanks anode I'll have a look to see how it goes.

[Dr Livingston]

Your first choice done wonders.

As a general observation your XML would be better as:

<?xml version='1.0' ?>
<root>
	<tab>
	    <title>
    	    <bold>Manage Employee's</bold>
	    </title>
    	<message>You may use the Quick Search below to administer an employee.</message>
	    <content>
        [ 
    	    <link href='index.php?Do=UserSearch&chr=A'>A</link> |
	        <link href='index.php?Do=UserSearch&chr=B'>B</link> |
			<link href='index.php?Do=UserSearch&chr=Z'>Z</link> |
        ]
	    </content>
	</tab>
</root>

[Andrew-J2000]

Keep all attributes encapsulated by double quotes rather than single

<?xml version="1.0" ?>
<root>
  <tab title="Manage Employee's" description="You may use the Quick Search below to administer an employee.">
    <content>
      [ <link href='index.php?Do=UserSearch&chr=A'>A</link> | <link href='index.php?Do=UserSearch&chr=B'>B</link> | <link href='index.php?Do=UserSearch&chr=Z'>Z</link> ]
    </content>
  </tab>
</root>

 

You maybe better off with something like this though

<?xml version="1.0" ?>
<root>
  <tab title="Manage Employee's" description="You may use the Quick Search below to administer an employee.">
    <link url="index.php?Do=UserSearch&chr=A" title="A" />
    <link url="index.php?Do=UserSearch&chr=B" title="B" />
  </tab>
</root>

and use xslt to handle the presentation...

[Dr Livingston]

Thanks folks, Andrew J2000 - your xml version looks better I think, though I'll change the links later; since I have it working just now and don't need to create more work for myself at this moment.

Karl - Good point, though there are 26 links I could tab the links in groups of 5 and return the next line back to the original tab space though ?

Thanks again folks.
