newbie: untangle nested attributes

iliad · Sep 17, 2005

hi,
i've the following questions:

1. why does..
<xsl:template match='dxl:text'>
<xsl:apply-templates/>
</xsl:template>
... results in "testing 123"? why does it writes this? shouldn't i
use a 'value-of' to create some output?

2. i can transform this xml piece..
<richtext>
<pardef id='3'/>
<par def='3'>
jdi
<run>

ojd
</run>
g
</par>
</richtext>"
... only in something like this: jdiodjojdg
How can I create this: jdiodjg

Thanks!!

Hi,

1. why does..
<xsl:template match='dxl:text'>
<xsl:apply-templates/>
</xsl:template>
.. results in "testing 123"?

Because you're code commands the XSLT processor to do so.
'<xsl:apply-templates/>' is equivalent to '<xsl:apply-templates select="node()"/>'

the 'dxl:text' element cotains two types of child nodes:
1. Text nodes (they are handled by a built-in default template that simply returns their value)
2. An element node: a 'break' elemwnt. You have defined a template for this element.
<xsl:template match='dxl:break'>
 
</xsl:template>

After the processing of the '<xsl:apply-templates/>', the result tree contains 3 child nodes as well:
1. a text node with value 'testing'
2. an elment 'BR'
3. a text node with value '123'

Because the output type was defined to be 'html', this looks after serialization like:
"testing 123"

If you do not want the 'BR' element, either delete the template that matches 'dxl:break' or use 'value-of'.

2. i can transform this xml piece..
<richtext>
<pardef id='3'/>
<par def='3'>
jdi
<run>

ojd
</run>
g
</par>
</richtext>"
.. only in something like this: jdiodjojdg
How can I create this: jdiodjg

Change the last template to:

<xsl:template match="dxl:run[dxl:font[@style='bold']]">
<xsl:value-of select = "."/>
</xsl:template>

Your situation might be simplified:

the xml becomes:
<line>
<bold/>
my text
</line>

the only template rule:
<xsl:template match="line/bold">
<xsl:value-of select=".."/>
</xsl:template>

What happens during the xslt process?

1. The 'line' element is encountered. No matching template is found.
Defaults to:
<xsl:template match="*">
<xsl:apply-templates select="node()"/>
</xsl:template>
All child nodes are processed. There 2 of them: a 'bold' element (step 2) and a text node (step 3)
2. The 'bold' element is encountered. A matching template is found.
my text is added to the result tree.
3. The text node is encountered. Its value is added to the result tree.

end result: "my textmy text"
____
What was my suggestion?
<xsl:template match="line[bold]">
<xsl:value-of select="."/>
</xsl:template>
(this matches any 'line' element that has a 'bold' child element)

Again, what happens during the xslt process?

1. The 'line' element is encountered. A matching template is found.
my text is added to the result tree.

That's it - no further processing.

end result: "my text"

Hope this helps,

regards,
