Builder Question

ruby-talk
1

Hey,

I'm trying to have Builder help me turn some YAML into XSLT that does
search and replace. I've gotten most of it down (and working a helluva
lot faster than YAML->XML->XSLT->XSLT...) but am struggling with a
couple of issues. Everybody will probably tell me to use a different
XML writer, and that's ok, I guess...

The documentation says I can declare a namespace like this:
  xml.SOAP :Envelope

How do I combine that with attributes? I'd like to do this, but it
doesn't work:
  xml.xsl :variable ("name"=>"cats") # and this in different orders

Nor does:
  xml.tag!("xsl:variable" "name"=>"cats") # and this with different
grouping

Also, is there any way to make elements with a '-' in the name, as in
<apply-templates/>?
This doesn't work:
   xml.apply-templates

In summary, is there a way to make this?
<xsl:stylesheet version="1.0">
   <xsl:apply-templates select="cats"/>
   ...
</xsl:stylesheet>

Many thanks,
Keith

Following code is untested, and just from the source:

The documentation says I can declare a namespace like this:

  xml.xsl :variable ("name"=>"cats") # and this in different orders

Did you try xml.xsl :variable, "name" => "cats" ?

Also, is there any way to make elements with a '-' in the name, as in
<apply-templates/>?
This doesn't work:
   xml.apply-templates

xml.tag! "apply-templates"

In summary, is there a way to make this?
<xsl:stylesheet version="1.0">
   <xsl:apply-templates select="cats"/>
   ...
</xsl:stylesheet>

xml.xsl :stylesheet, "version" => "1.0" do
  xml.xsl "apply-templates", "select" => "cats" do
    ...
  end
end

(I hope that works. :-))

Ah, that works great. (How can I not have tried that...?)

xml.tag! "apply-templates"

Yep, that's good.

xml.xsl :stylesheet, "version" => "1.0" do
xml.xsl "apply-templates", "select" => "cats" do
...
end
end

Ah, do, instead of a { |block| }...

Alas, it gives me:
xsl:stylesheet version="1.0">
  <xsl select="cats">apply-templates</xsl>
</xsl:stylesheet>

But it led me to this hack:

xml.xsl :stylesheet, "version" => "1.0" do
  xml.tag! 'xsl:apply-templates select="cats"'
end

Which works!

Thanks a bunch!

Other responses on how to do this better still happily accepted :-).

Thanks,
Keith

Interesting... oh, I forgot a :

xml.xsl :stylesheet, "version" => "1.0" do
  xml.xsl :"apply-templates", "select" => "cats" do
    ... #^^^
  end
end

But it led me to this hack:

Really a hack. Yuck. :wink:

Thanks a bunch!

You're welcome.

Hooray! You get 20pts for answering a quesiton while I was writing the
email asking it.

Yeah, it doesn't really work except for one-line tags.

Here's an example of the problem:
    <xsl:variable name="elem-contents">
      <xsl:value-of select="substring(., 2, $end-pos)"/>
    </xsl:variable name="elem-contents">

Thanks again,
Keith
