GoldenDict是一款跨平台的词典软件，支持各种不同格式的在线/离线词典，支持划词翻译等。

对于在线词典，GoldenDict会把网页的内容内嵌到软件主页面或者划词翻译的弹窗中。 但是有个问题，在线词典的页面内容中通常有很多无用空间，比如空白，广告等，使用起来体验不佳。

GoldenDict的在线词典没有提供展示页面部分内容的功能，为了达到在界面中重新格式化在线词典内容的目的，可以通过program类型的词典。通过我们自定义的程序来处理在线词典的返回网页供GoldenDict读取。

以下方案程序基于https://github.com/goldendict/goldendict/issues/105#issuecomment-213533788 做了修改， 可以把iciba的搜索框以及释义上的广告去掉，把bing词典的搜索框去掉，节省显示空间。

配置方法

  1. 设置Program类型的词典分别为：
    • iciba /path/getxpath http://www.iciba.com/word?w=%GDWORD% "" "" "" ['/html/body/div/main/div[position()<3]','/html/body/div/div']
    • bing /path/getxpath https://cn.bing.com/dict/search?q=%GDWORD% "" "" "" ['/html/body/header']
  2. /path/getxpath内容如下，脚本需要执行权限。基本原理就是获取到词典的网页内容，按需修改后返回：
#!/usr/bin/python3
import urllib.request
import urllib.parse
import sys
from lxml.html import fromstring, tostring

通过本地脚本输出html的方式可能造成页面上有些功能不可用，例如事件函数可能注册不上。
