Finding all paths in an XML document

[Ghislain Mary]

Hi all,

I'd like to know how you would search for all the paths of an XML
document using REXML. For example, let say that the document is the
following:

<document>
<content>a simple sample</content>
<node>
<content>some text</content>
</node>
<node>
<foo>
<content>an other sample</content>
</foo>
</node>
</document>

What I'd like to have is an Array like this:
[['content'],
['node'],
['node', 'content'],
['node', 'foo'],
['node', 'foo', 'content']]

Any ideas ?

Thanks,

Ghislain

This might help:

require "rexml/document"

doc = File.open( "doc.xml" ){|io| REXML:ocument.new io}

doc.elements.each( "//*" ) do |el|
p el.xpath.split(%r{/})
end

Alternative:

require "rexml/document"

doc = File.open( "doc.xml" ){|io| REXML:ocument.new io}

doc.elements.each "//*" do |el|
path = []
par = el

while par
path.unshift par.name
par = par.parent
end

path.shift
p path
end

Kind regards

That worked fine.

Thanks a lot Robert.
