HTML Output from XML Problem

[ritchielee]

Hi

I have the following partial structure in some XML and I am using HTML
Builder for output.

<narrative-paragraph number="1"> text text text text text text
text text text </narrative-paragraph>

<narrative-paragraph number="2"> text text text text text text
text text <narrative-xref number="1"></narrative-xref> text text
text text text text text text </narrative-paragraph>

etc

The following code works to give me a heading and paragraph - but I
can't for the life of me figure out how to keep the links in situ -
they get stripped out of their location and bunch up at the end of
each paragraph. I figure this is how I have my loop placed, but other
than this I can't get them to output at all.

xmz = File.open("chapter.xml", "r")

xm = Nokogiri::XML.parse(xmz)

builder = Nokogiri::HTML::Builder.new do |doc|

doc.html {
doc.body {

xm.xpath('//narrative-paragraph').each do |para|

doc.p.heading(:id => para['number']) { doc.text para
['number'] }

doc.p.paratext {doc.text para.content
xm.css('narrative-paragraph narrative-
xref').each do |link|
a(:href => "#" + link['number']) { doc.text
link['number'] }
end }
end

...

Current output
-------------------
<p class="heading" id="2">2</p>
<p class="paratext">text text text text text text text text
text text text text text text text text
<a href="#2">2</a></p>

Ritchie

It's tough to figure out what exactly you're doing here. What are the exact contents of chapter.xml?

It would be really helpful if you posted a gist of a sample case that is entirely self-contained (including XML or HTML input), and a description of what your expected output is.
 

 xmz = File.open("chapter.xml", "r")

  xm = Nokogiri::XML.parse(xmz)

  builder = Nokogiri::HTML::Builder.new do |doc|

 doc.html {
       doc.body {

         xm.xpath('//narrative-paragraph').each do |para|

           doc.p.heading(:id => para['number']) { doc.text para
['number'] }

           doc.p.paratext {doc.text para.content
                     xm.css('narrative-paragraph narrative-
xref').each do |link|
                       a(:href => "#" + link['number']) { doc.text
link['number'] }
                     end }
           end

...

Current output
-------------------
<p class="heading" id="2">2</p>
<p class="paratext">text  text  text  text  text  text  text  text
text  text  text  text  text  text  text  text
<a href="#2">2</a></p>

Child elements are getting duplicated and bunched together at the end
of each narrative-paragraph. What I need to fathom is how to gather
the processed children up in para.content and not loop and duplicate
them at the end.

Current code & output:

xm.css('narrative-paragraph').each do |para|

doc.p.npt(:id => para['number']) { doc.text para
['number'] }
doc.p.np { doc.text para.content

xm.css('narrative-paragraph narrative-xref').each
do |xref|
doc.a(:href => "#" + xref['number'])
{ doc.text xref['number'] }
end

xm.css('narrative-paragraph para-
text').each do |paratext|
doc.span.paratext { doc.text
paratext.content }
end

xm.css('narrative-paragraph legis-
cite').each do |legiscite|
doc.span.legiscite
{ doc.text legiscite.content }
end

}...

outputs...

Do you think you can put together a stand-alone example that we can
run? I can't really tell what is going on in this example, and I'm
afraid I can't be much help unless I get some code I can actually
execute to reproduce the problem.

Thanks.

Hi, If it helps, I've sorted out a much simpler gist:

I'm trying with:
xmz = File.open("short.xml", "r")

xm = Nokogiri::XML.parse(xmz)


builder = Nokogiri::HTML::Builder.new do |doc|
doc.html {
doc.body {

doc.div.wrapper! {
doc.h1 "Short"

xm.css('paragraph').each do |para|

doc.h3.para(:id => para['number']) { doc.text para
['number'] }

doc.p.narrativeparagraph {

xm.css('paragraph inner-section').each do
|section|
doc.span.innersection { doc.text
section.content

xm.css('inner-section

xref').each do |xref|
doc.a(:href => "#" + xref
['number']) { doc.text xref['number'] }
end

xm.css('paragraph inner-
text').each do |innertext|
doc.span.innertext
{ doc.text innertext.content }
end

} end #inner-section

}

end#end paragraph
}#end wrapper
}#end body
}#end html
end#end builder

outfile = File.new("short_output.html", "w")
outfile.puts builder.to_html
outfile.close


on:

<?xml version="1.0"?>

<looseleaf>

<paragraph number="1">
<inner-section> blah one blah <xref number="link1location"></
xref>
<inner-text> blah two blah blah </inner-text>
blah three
</inner-section>
</paragraph>

<paragraph number="2">
<inner-section> blah four blah <xref number="link2location"></xref>
<inner-text>blah five blah blah </inner-text>
blah six
</inner-section>
</paragraph>

</looseleaf>

Hi Aaron
Did I supply enough info for you to see what my
duplication problem is; were you able to run the code?

Here is my current output from this last example - so instead of just
formatting the contents of each paragraph, it removes the xrefs from
where they were originally and duplicates elements across paragraphs.
I'm so sorry about this - all I want it to do is swap from xml to html
tags - just like the structure at the end of my last post.

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://
www.w3.org/TR/REC-html40/loose.dtd">
<html><body><div id="wrapper">
<h1>Short</h1>
<h3 class="para" id="1">1</h3>
<p class="narrativeparagraph">

<span class="innersection"> blah one blah blah two blah blah blah
three

<a href="#link1location">link1location</a>

<a href="#link2location">link2location</a>

<span class="innertext"> blah two blah blah </span>

<span class="innertext">blah five blah blah </span>

</span>

<span class="innersection"> blah four blah blah five blah blah blah
six

<a href="#link1location">link1location</a>

<a href="#link2location">link2location</a>

<span class="innertext"> blah two blah blah </span>

<span class="innertext">blah five blah blah </span>

</span>
</p>


<h3 class="para" id="2">2</h3>
<p class="narrativeparagraph">

<span class="innersection"> blah one blah blah two blah blah blah
three

<a href="#link1location">link1location</a>

<a href="#link2location">link2location</a>

<span class="innertext"> blah two blah blah </span>

<span class="innertext">blah five blah blah </span>

</span>

<span class="innersection"> blah four blah blah five blah blah
blah six

<a href="#link1location">link1location</a>

<a href="#link2location">link2location</a>

<span class="innertext"> blah two blah blah </span>

<span class="innertext">blah five blah blah </span>

Any noobs in the same boat as me - I've backed out of trying to use
Builder and I'm getting there slowly but surely with:

frag.xpath("//paragraph").each { |div| div.name= "p";
div.set_attribute("class" , "narrativeparagraph") }

frag.css('inner-section xref').each { |xref| xref.name= "a";
xref.set_attribute("href" , "#" + xref['number']); xref.content = xref
['number'] }
