维基百科的站点摘要提要，不包括单个用户 [英] Site summary feed of Wikipedia excluding a single user

问题描述

有一个最近的变化"维基百科主页上提供的提要.

There is a "Recent changes" feed available on the Wikipedia homepage.

同样也可用作 ATOM 提要.也可以通过转到他们的 user_account 并选择提要来观看单个用户.但是，除了一(或两个)用户之外，有没有办法访问提要?

The same is also available as an ATOM feed. It is also possible to watch a single user by going to their user_account and selecting the feed. But is there any way to get to the feed excluding one (or two) users?

更新:使用 xmllint 我可以提取作者姓名.

Update: Using xmllint I can extract the author names.

wget https://hunspell.s3.amazonaws.com/temp/out.txt

xmllint --xpath "//*[name() = 'feed']/*[name() = 'entry']/*[name() = 'author']/*[name() = 'name']" out.txt

但我想从这个提要中排除一两个作者.例如，Clarityfiend 和 Shortride.

But I want to exclude one or two authors from this feed. For example, Clarityfiend and Shortride.

更新:

当我尝试 xpath 命令时，它使用一个参数(英文)运行良好.但它以 Unicode 参数失败:

When I tried xpath command, it worked very well with one parameter (english). But it failed with a Unicode parameter:

wget https://hunspell.s3.amazonaws.com/todel/out.txt

工作:

xpath -e "/feed/entry[author/name!='Aditya tamhankar' and author/name!='Sushant Madhale']" out.txt > a.txt

没有用:

xpath -e "/feed/entry[author/name!='Aditya tamhankar' and author/name!='संतोष गोरे']"  out.txt > filtered.txt

第二作者的条目仍然存在于过滤输出中.

The entry by the second author is still there in filtered output.

grep 'संतोष गोरे' filtered.txt

---

第二个命令对 Unicode 没问题，但它没有正确显示一条记录...

---

The second command is OK with Unicode, but it does not display one record correctly...

# (t1='Aditya tamhankar' ; t2='संतोष गोरे'; echo 'setns x=http://www.w3.org/2005/Atom'; echo "cat /x:feed/x:entry[not(x:author/x:name[.='$t1'] | x:author/x:name[.='$t2'])]/descendant::*[self::x:updated or self::x:title or descendant-or-self::x:name]/text()") | xmllint --shell out.txt  | tail -n +4 | gawk '{ if(NR % 6 == 0){ print $0 "¬"} else { print $0 }}' |gawk 'BEGIN{FS="\n -------\n" ; RS="\n -------¬\n"; OFS="||"} { print $2,$1,$3 }END{ print FNR}'

除此之外的所有记录都是正确的:

All records except this one are correct:

推荐答案

我建议你使用终端中的 xpath 工具(Ubuntu 包 libxml-xpath-perl).它支持 XPath 2:

I suggest that you use xpath tool from your terminal (Ubuntu package libxml-xpath-perl). It supports XPath 2:

wget -O - https://hunspell.s3.amazonaws.com/temp/out.txt | xpath -e "/feed/entry[author/name!='Clarityfiend' and author/name!='Shortride']" > filtered.txt

UPD:如果输入缓冲区出现内存不足错误，请将提要下载到文件而不是标准输出中:

UPD: If there is an out of memory error for input buffer, download the feed into a file rather than standard output:

wget https://hunspell.s3.amazonaws.com/temp/out.txt
xpath -e "/feed/entry[author/name!='Clarityfiend' and author/name!='Shortride']" out.txt > filtered.txt

XPath 查询将列出作者姓名不等于 Clarityfiend 或 Shortride 的所有条目.条目将保存在 filtered.txt 中.

The XPath query will list all entries with author's name not equal to Clarityfiend or Shortride. The entries will be saved in filtered.txt.
