Using IF statements for differentiating between several xhtml metatags

Post by **LMCGIB10** » Fri Feb 24, 2012 8:10 pm

Hi,

In my source xhtml I have three metatags in the head as follows:


<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

	<title>blah blah</title>

	 

	<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>

    <meta name="keywords" content="keywordone, keywordtwo, keywordthree" />

	 

<meta name="revised" content="2010-2-15T14:50:7+0"/>

...

</head>

In my xslt, I currently have

Code: Select all


    <xsl:template match="html:meta"

    <dc:modified>

        <xsl:value-of select="@content"/>

    </dc:modified>

which returns

Code: Select all


<dc:modified>text/html; charset=UTF-8</dc:modified>

<dc:modified>keywordone, keywordtwo, keywordthree</dc:modified>

<dc:modified>2010-2-15T14:50:7+0</dc:modified>

However I would like the follwing

Code: Select all


<dc:content>text/html; charset=UTF-8</dc:content>

<dc:description>keywordone, keywordtwo, keywordthree</dc:description>

<dc:modified>2010-2-15T14:50:7+0</dc:modified>

So I thought about using <xsl:if>, but really don't know the syntax for working it through.

I would like to implement something like:

Code: Select all


If

 @meta, content=date format 

 then

 <dc:modified>

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

 <dc:modified>

else if

 @meta, content=keywordone, ...

 then

 <dc:description>

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

 <dc:modified>

else

 @meta, content=text/html

 then

 <dc:content>

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

 <dc:content>

Any suggestions or help would be excellent.
Kind Regards

Lewis

Hi,

It's simple, use a more explicit XPath match for each type of meta. The order is also important, the most generic match must be used at the end:

Code: Select all


    <xsl:template match="html:meta[@name='keywords']"

    <dc:description>

        <xsl:value-of select="@content"/>

    </dc:description>



    <xsl:template match="html:meta[@name='revised']"

    <dc:modified>

        <xsl:value-of select="@content"/>

    </dc:modified>



    <xsl:template match="html:meta"

    <dc:content>

        <xsl:value-of select="@content"/>

    </dc:content>

Regards,
Adrian
