Edit docx with nokogiri and rubyzip

Question

Here I use rubyzip and nokogiri to modify the .docx file.

RubyZip -> Unzip .docx file
Nokogiri -> Parse and change in content of the body of word/document.xml

As I wrote the sample code just below, but the code changed the file, but other files were violated. In other words, the updated file does not open, indicating that the word processor has crashed. How can I solve this problem?

require 'zip/zipfilesystem'
require 'nokogiri'
zip = Zip::ZipFile.open("SecurityForms.docx")
doc = zip.find_entry("word/document.xml")
xml = Nokogiri::XML.parse(doc.get_input_stream)
wt = xml.root.xpath("//w:t", {"w" => "http://schemas.openxmlformats.org/wordprocessingml/2006/main"}).first
wt.content = "FinalStatement"
zip.get_output_stream("word/document.xml") {|f| f << xml.to_s}
zip.close

Answer 1

According to the official Github documentation you should Use write_buffer instead open. The link also has sample code.

, .docx. . docx , u , My_Class.rb . . , rubyzip nokogiri gem gemset (Google ).

require 'rubygems'
require 'zip/zipfilesystem'
require 'nokogiri'
class Edit_docx
def initialize
coupling =  [('a'..'z'),('A'..'Z')].map{|i| i.to_a}.flatten
secure_string  =  (0...50).map{ coupling[rand(coupling.length)] }.join
FileUtils.cp 'template.docx', "#{secure_string}.docx"
zip = Zip::ZipFile.open("#{secure_string}.docx")
doc = zip.find_entry("word/document.xml")
xml = Nokogiri::XML.parse(doc.get_input_stream)
wt = xml.root.xpath("//w:t", {"w"=>"http://schemas.openxmlformats.org/wordprocessingml/2006/main"})
#puts wt
wt.each_with_index do |tag,i|
tag.content = i.to_s + ""
end
zip.get_output_stream("word/document.xml") {|f| f << xml.to_s}
zip.close
puts secure_string
#FileUtils.rm("#{secure_string}.docx")
end
N.new
end
