XML Builder

my code looks like this:
xml.instruct!
xml.county(name: @jurisdiction.name, id: @jurisdiction.jurisdictionID) do
  xml.officials do
    @officials.each do |official|
      xml.official do
        xml.firstname official.firstname
        xml.lastname official.lastname
        xml.eotypeID eotypeID: official.eotypeID
        xml.eotype EoType.find(official.eotypeID).name
        xml.sourceID sourceID: official.sourceID
        xml.source SourceType.find(official.sourceID).name
      end
    end
  end
end

which produces this:

<county name="Some Town" id="9999999999">
  <officials>
    <official>
      <firstname>Hector</firstname>
      <lastname>Someone</lastname>
      <eotypeID eotypeID="1"/>
      <eotype>Primary</eotype>
      <sourceID sourceID="1"/>
      <source>State Web Site</source>
    </official>
    <official>
      <firstname>Lucy</firstname>
      <lastname>Someone-Else</lastname>
      <eotypeID eotypeID="3"/>
      <eotype>Registration</eotype>
      <sourceID sourceID="6"/>
      <source>History</source>
    </official>
  </officials>
</county>

I would like to change it to produce this:

<county name="Some Town" id="9999999999">
  <officials>
    <official>
      <firstname>Hector</firstname>
      <lastname>Someone</lastname>
      <eotypeID eotypeID="1"/>
      <eotype>Primary</eotype>
      <sourceID sourceID="1"/>
      <source>Web Site</source>
    </official>
    <official>
      <firstname>Lucy</firstname>
      <lastname>Someone-Else</lastname>
      <eotype eotypeID="3">Registration</eotype>
      <source sourceID="6">History</source>
    </official>
  </officials>
</county>

I cannot find any documentation or examples on the point. Can someone offer 
a helpful hint or point to some useful documentation that covers the 
subject, where the primary point is this:  Using XML Builder, or some other 
facility, how does one emit an element instance that has both attributes 
and non-empty content?  There are losts of ways to do it with brute force; 
just trying to find an "elegant" solution.

Thanks for any suggestions

Re: XML Builder

My previous post on this question had an error in the resired target 
description.  Here is it aagain; apologies for any confusion:

my code looks like this:
xml.instruct!
xml.county(name: @jurisdiction.name, id: @jurisdiction.jurisdictionID) do
  xml.officials do
    @officials.each do |official|
      xml.official do
        xml.firstname official.firstname
        xml.lastname official.lastname
        xml.eotypeID eotypeID: official.eotypeID
        xml.eotype EoType.find(official.eotypeID).name
        xml.sourceID sourceID: official.sourceID
        xml.source SourceType.find(official.sourceID).name
      end
    end
  end
end

which produces this:

<county name="Some Town" id="9999999999">
  <officials>
    <official>
      <firstname>Hector</firstname>
      <lastname>Someone</lastname>
      <eotypeID eotypeID="1"/>
      <eotype>Primary</eotype>
      <sourceID sourceID="1"/>

      <eotypeID eotypeID="3"/>
      <eotype>Registration</eotype>
      <sourceID sourceID="6"/>
      <source>History</source>
    </official>
  </officials>
</county>

I would like to change it to produce this:

<county name="Some Town" id="9999999999">
  <officials>
    <official>
      <firstname>Hector</firstname>
      <lastname>Someone</lastname>

Long story short: pass it the content, and then the attributes.  (Or
the other way around, but then I think you''d have to put the
attributes in braces (since it''s a hash and you''ll have stuff
after
it), and put parens on the call (so Ruby doesn''t think the hash is a
block).)

In your case, if I correctly spotted the difference between the
current and desired outputs, what I think you want would be:

        xml.eotype EoType.find(official.eotypeID).name,
                   eotypeID: official.eotypeID
        xml.source SourceType.find(official.sourceID).name,
                   sourceID: official.sourceID

Or, to reduce unclear redundancy:

        eo_id = official.eotypeID
        xml.eotype EoType.find(eo_id).name, eotypeID: eo_id
        src_id = official.sourceID
        xml.source SourceType.find(src_id).name, sourceID: src_id

Or, with the attributes hash first:

        eo_id = official.eotypeID
        xml.eotype({ eotypeID: eo_id }, EoType.find(eo_id).name)
        src_id = official.sourceID
        xml.source({ sourceID: src_id }, SourceType.find(src_id).name)

Try any of these (I''d favor #2) and let me know if it gets you what you
want.

RE: XML Builder

Dave,

You nailed it.  Either way works fine.  I could not find a reference
with the grammar explained as you do below, at least not in the specific
XML Builder context.

Thanks.
