output XML nodes out into individual files - ruby

Question

I am trying to create individual files from the nodes of a XML file. My issue is no matter what way I try it I seem to be getting stuck in a nested loop and I either keep rewriting each file until they are just the same node data over and over, or I run all of the nodes per loop instance. I'm sure this should be pretty easy but I'm getting hung up somewhere.
doc = Nokogiri::XML(open("original_copy_mod.xml"))
doc.xpath("//nodes/node").each do |item|
item.xpath("//div[#class='meeting-date']/span/#content").each do |date|
date = date.to_s
split_date = date.split('T00')
split_date = split_date[0].gsub("-","_")
split_date = split_date + ".pcf"
File.open(split_date,'w'){ |f| f.write(item)}
end
end
This is another attempt that I don't understand why is failing to create all the pages. This only creates one page, but if I use a "puts" the count does iterate through all 101 nodes.
doc = Nokogiri::XML(open("original_copy_mod.xml"))
doc.xpath("//nodes/node").each do |item|
date = item.xpath("//no-name/div[#class='meeting-date']/span/#content").to_s
split_date = date.split('T00')
split_date = split_date[0].gsub("-","_")
split_date = split_date + ".pcf"
File.open(split_date,'w'){ |f| f.write(item)}
end
For further clarification, this is an example of the nodes that I'm trying to create into pages.
<?xml version="1.0" encoding="UTF-8" ?>
<nodes>
<node>
<no-name><div class="meeting-title">Meeting-a</div>
<div class="meeting-date"><span class="date-display-single" property="dc:date" datatype="xsd:dateTime" content="a-2021-11-29T00:00:00-06:00">Monday, November 29, 2021</span></div>
</no-name>
<no-name><div class="past-mtg-icons">
<div>
<span><img src="agenda-icon.svg"/></span>
<span>Agenda</span>
</div>

Answer 1

date = item.xpath("//no-name/div[#class='meeting-date']/span/#content").to_s
By using // you are breaking out of the scope of the node you are iterating in. Removing the slashes you preserve the scope of the node.
date = item.xpath("no-name/div[#class='meeting-date']/span/#content").to_s

Answer 2

When you use w option it always rewrite onto the file. What you need is to create or append to the file, it's done with the a option. So you can try this:
File.open(split_date,'a'){ |f| f << item }
PS. Be sure that split_date as the name of the file is uniq for each node since you want a separate file per node
