[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] decorator / wrapper design pattern
 Hi,
I'm using XSL version 1.0 and am trying to use the decorator design
pattern, but can't get it to work in XSL.
Here is what I try to achieve:
Different types of elements all need to be surrounded by the same text.
For example:
I've XML:
<base>
<section>
<title>the title</title>
<paragraph>some text</paragraph>
<paragraph>more text</paragraph>
</section>
<section>
<title>the title</title>
<paragraph>other text</paragraph>
<paragraph>more other text</paragraph>
<paragraph>and more text</paragraph>
</section>
</base>
Now I want all text in titles and in paragraphs to be italic and in
titles also to be bold.
My first thought was to use call-template like this:
<xsl:template match="title">
<xsl:call-template name="bold">
<xsl:call-template name="italic">
<xsl:value-of select="."/>
</xsl:call-template>
</xsl:call-template>
</xsl:template>
But this is not the way to do this.
I cannot however figure out or find the solution. The decoration that
must be applied is much more complicated than bold or italic, but that
is besides the point, I think.
Here is my second try, but here is the problem that I cannot nest
decorators, so bold and italic is not possible on the same element:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:template match="/">
<xsl:call-template name="body"/>
</xsl:template>
<xsl:template match="section">
<xsl:apply-templates />
<br/>
</xsl:template>
<xsl:template match="title">
<xsl:call-template name="bold" />
<br/>
</xsl:template>
<xsl:template match="paragraph">
<xsl:call-template name="italic" />
</xsl:template>
<xsl:template name="bold">
<b>
<xsl:apply-templates/>
</b>
</xsl:template>
<xsl:template name="italic">
<i>
<xsl:apply-templates/>
</i>
</xsl:template>
<xsl:template name="body">
<html>
<body>
<xsl:apply-templates />
</body>
</html>
</xsl:template>
</xsl:stylesheet>
Can anybody give me a pointer?
Thanks in advance
