给定一个像这样的 xml 字符串:

<some><nested><xml>value</xml></nested></some>

什么是最好的选择(使用 ruby​​)将它格式化成可读的东西:

<some>
  <nested>
    <xml>value</xml>
  </nested>
</some>

最佳答案

require "rexml/document"
include REXML

source ='<some><nested><xml>value</xml></nested></some>'
doc = Document.new( source )
doc.write( targetstr = "", 2 ) #indents with 2 spaces
puts targetstr

#write 写入任何需要

doc.write( $stdout, 2 )
doc.write( an_open_file, 2 )
