私の目標：件名のxmlドキュメントで「SECTION」という名前のすべての要素を取得したいと思います。各セクションとその下のすべてを取得します。

制約：LibXMLRubyを使用する必要があります。つまり、「xml」が必要です。

問題：出力データが切り捨てられます。

質問（出力file1.xmlを参照）：

  • file1.xmlの出力が切り捨てられるのはなぜですか？注：最初のP（a）... / Pタグの間のテキストの多く（注：切り捨ては「倫理...」という単語で始まります）
  • コードが最後の2つのP要素（P（b）...、P（2）...）とCITA要素を削除したのはなぜですか？何が原因ですか？xml version = "1.0" encoding = "UTF-8"？およびSECTION/を出力の最後に表示しますか？

注：出力file2.xmlには、さらに厳しい切り捨てがあります。それが何かを明らかにする場合に備えて、私はそれを含めています。

コードは次のとおりです。

#!/usr/bin/ruby
require "xml"
reader = XML::Reader.file('infile2.xml')
while reader.read
  node = reader.node 
    if node.name == "SECTION"
      iteration = XML::Document.string(node.to_s)
      puts iteration
      puts "\n"
    end
end

入力file1.xml：

巨大な XML ドキュメントがない限り、代わりに次のようなものを検討してください。

require "xml"
doc = XML::Document.file('infile1.xml')
doc.find('/SECTION').each do |s|
  puts "[#{s}]"
end

これは以下を出力します:

<SECTION>
  <SECTNO>§ 0.735-1</SECTNO>
  <SUBJECT>Agency ethics officials.</SUBJECT>
  <P>(a) <E T="03">Designated Agency Ethics Official (DAEO).</E> The Assistant General Counsel (023) is the designated agency ethics official (DAEO) for the Department of Veterans Affairs.

これは質問への回答ではなく、回避策です。

リーダーを使用する際の実際の問題が何であるかはわかりませんが、カーソルっぽいことに関係があると思われます。たとえば、次のように動作します。最初の XML ドキュメントにはまだ空のセクションが追加されています。

if node.name == "SECTION"
  puts "#{reader.read_outer_xml}"
end
