cURL awk { 打印 } 帮助

发布于 2024-10-19 02:48:58 字数 368 浏览 1 评论 0原文

我在一个文件中有这个：

<yweather:condition  text="Partly Cloudy"  code="29"  temp="56"  date="Wed, 23 Feb 2011 6:53 pm MST" />

我正在使用此代码来尝试打印“部分多云”，尽管只有“部分”没有被打印。

grep "yweather:condition" ~/Documents/weather.dat | awk '{ print $2 }' | awk 'BEGIN { FS = "[\"]" } ; { print $2 } '

希望有人能解释如何打印这两个词。谢谢！

I have this in a file:

<yweather:condition  text="Partly Cloudy"  code="29"  temp="56"  date="Wed, 23 Feb 2011 6:53 pm MST" />

I'm using this code to try and print "Partly Cloudy", although only "Partly" is not getting printed.

grep "yweather:condition" ~/Documents/weather.dat | awk '{ print $2 }' | awk 'BEGIN { FS = "[\"]" } ; { print $2 } '

Hopefully someone can explain how to get both words to print. Thanks!

cat ~/Documents/weather.dat |awk 'BEGIN { FS = "[\"]" } ; /yweather:condition/ { print $2 } '

取代这一切

cat ~/Documents/weather.dat |awk 'BEGIN { FS = "[\"]" } ; /yweather:condition/ { print $2 } '

Replaces all that

$ echo "<yweather:condition  text="Partly Cloudy"  code="29"  temp="56"  date="Wed, 23 Feb 2011 6:53 pm MST" />" | awk '/weather/{gsub(/.*text=|code=.*/,"")}1'
Partly Cloudy

$ echo "<yweather:condition  text="Partly Cloudy"  code="29"  temp="56"  date="Wed, 23 Feb 2011 6:53 pm MST" />" | ruby -e 'puts gets.scan(/text=(.*)code=/)'
Partly Cloudy

如果您遇到更复杂的情况，请使用真正的 XML/HTML 解析器。

$ echo "<yweather:condition  text="Partly Cloudy"  code="29"  temp="56"  date="Wed, 23 Feb 2011 6:53 pm MST" />" | awk '/weather/{gsub(/.*text=|code=.*/,"")}1'
Partly Cloudy

$ echo "<yweather:condition  text="Partly Cloudy"  code="29"  temp="56"  date="Wed, 23 Feb 2011 6:53 pm MST" />" | ruby -e 'puts gets.scan(/text=(.*)code=/)'
Partly Cloudy

If you have more complex situations, use a real XML/HTML parser.
