Hi Emmett,
I think what you want to manipulate is xmlSaveNoEmptyTags[1] sadly, I don't
know
enough C and can't find anything similar to try to copy.
All that said, Trans' hack is a good one:
$ irb --prompt xmp libxml2.irb && cat output.xml
require 'rubygems' # if installed via Gems
# => true
require 'xml/libxml'
# => true
doc = XML::Document.new()
# => <?xml version="1.0"?>
doc.root = XML::Node.new('root_node')
# => <root_node/>
root = doc.root
# => <root_node/>
root << elem1 = XML::Node.new('elem1', "")
# => <elem1></elem1>
elem1['attr1'] = 'val1'
# => "val1"
elem1['attr2'] = 'val2'
# => "val2"
root << elem2 = XML::Node.new('elem2', "")
# => <elem2></elem2>
elem2['attr1'] = 'val1'
# => "val1"
elem2['attr2'] = 'val2'
# => "val2"
root << elem3 = XML::Node.new('elem3', "")
# => <elem3></elem3>
# Namespace hack to reduce the numer of times XML:: is typed
include XML
# => Object
root << elem7 = Node.new('foo')
# => <foo/>
1.upto(10) {|i| elem7 << n = Node.new("bar#{i}", "") }
# => 1
format = true
# => true
doc.save('output.xml', format)
# => 352
<?xml version="1.0"?>
<root_node>
<elem1 attr1="val1" attr2="val2"></elem1>
<elem2 attr1="val1" attr2="val2"></elem2>
<elem3></elem3>
<foo>
<bar1></bar1>
<bar2></bar2>
<bar3></bar3>
<bar4></bar4>
<bar5></bar5>
<bar6></bar6>
<bar7></bar7>
<bar8></bar8>
<bar9></bar9>
<bar10></bar10>
</foo>
</root_node>
HTH,
Keith
