在上面的 SOAP API 响应中，我需要解析 TicketNumber，它存在于 <TicketNumber xsi:type="xsd:string">REQ00000007865.0002</TicketNumber>.

之间

有没有办法在 shell 脚本中使用 sed 或 awk 来实现此目的？

我尝试了以下方法，但没有任何效果：

sed -n 's|<TicketNumber xsi:type="xsd:string">\(.*\)</TicketNumber>||p' response.xml

Answer 1

也许就是这样，在grep和perl的帮助下：

grep "TicketNumber" response.xml | perl -pe 's/.*>(.*)<.*//'

这里的想法是用 grep 隔离 TicketNumber 标签，然后用 perl 捕获标签内的任何内容。

免责声明：使用专用 XML 解析器（如果可用）

POSIX 解法：

awk -F'[<>]' '/TicketNumber/ {print }' file
