我正在使用
rubyzip和nokogiri的组合来编辑.docx文件.我正在使用rubyzip来解压缩.docx文件,然后使用nokogiri来解析和更改word / document.xml文件的主体但是有时候我最后关闭rubyzip它会破坏文件而我无法打开它或者修理它.我在桌面上解压缩.docx文件并检查word / document.xml文件,并将内容更新为我更改为的内容,但所有其他文件都搞砸了.有人可以帮我解决这个问题吗？这是我的代码：
require 'rubygems'
require 'zip/zip'
require 'nokogiri'
zip = Zip::ZipFile.open("test.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 = "New Text"
zip.get_output_stream("word/document.xml") {|f| f << xml.to_s}
zip.close
解决方法
昨晚我遇到了与rubyzip相同的腐败问题.我通过将所有内容复制到新的zip文件来解决它,根据需要替换文件.
这是我的工作概念证明：
#!/usr/bin/env ruby
require 'rubygems'
require 'zip/zip' # rubyzip gem
require 'nokogiri'
class WordXmlFile
def self.open(path,&block)
self.new(path,&block)
end
def initialize(path,&block)
@replace = {}
if block_given?
@zip = Zip::ZipFile.open(path)
yield(self)
@zip.close
else
@zip = Zip::ZipFile.open(path)
end
end
def merge(rec)
xml = @zip.read("word/document.xml")
doc = Nokogiri::XML(xml) {|x| x.noent}
(doc/"//w:fldSimple").each do |field|
if field.attributes['instr'].value =~ /MERGEFIELD (\S+)/
text_node = (field/".//w:t").first
if text_node
text_node.inner_html = rec[$1].to_s
else
puts "No text node for #{$1}"
end
end
end
@replace["word/document.xml"] = doc.serialize :save_with => 0
end
def save(path)
Zip::ZipFile.open(path,Zip::ZipFile::CREATE) do |out|
@zip.each do |entry|
out.get_output_stream(entry.name) do |o|
if @replace[entry.name]
o.write(@replace[entry.name])
else
o.write(@zip.read(entry.name))
end
end
end
end
@zip.close
end
end
if __FILE__ == $0
file = ARGV[0]
out_file = ARGV[1] || file.sub(/\.docx/,' Merged.docx')
w = WordXmlFile.open(file)
w.force_settings
w.merge('First_Name' => 'Eric','Last_Name' => 'Mason')
w.save(out_file)
end
