我有一个很大的事务日志文件。在那下面是XML响应字符串（特别是在erricson IN日志中）。我只想要响应代码和这个值。目前，当我在linux上使用grep时，所有完整的字符串都会出现。
以下是我的日志条目：

以下是我用于此的命令，但它无法正常工作：
grep 'responseCode' TransactionLog.log.21_05_2015-12|egrep "<member>.*</member>"
预期输出将是：
responseCode</name><value><i4>0</i4>
答案 0 :(得分：0)
日志条目是非常长的XML行。 grep命令仅查找包含匹配模式的整行。 grep命令找到了匹配的行并为您输出 - 只是它是一个非常长的行。
您想要只提取它找到的行的一部分。最好使用其他工具，例如perl或awk。您还可以使用sed将单行切成成员标记的多行，然后grep查找您想要的特定项目。
使用sed来添加换行符有点尴尬，但在这个问题/答案中对此进行了解释：How to insert a newline in front of a pattern?
在每个＆lt; member＆gt;处打破这一行您可以写这个条款：
sed -e 's/<member>/\'$'\n<member>/g'
然后你只能选择ResponseCode部分，给出：
grep responseCode Transaction.log | sed -e 's/<member>/\'$'\n<member>/g' | grep responseCode
现在生成的输出是：
<member><name>**responseCode</**name><value**><i4>0</i4></**value></member>
现在，您可以使用sed：
将其删除一点grep responseCode Transaction.log | sed -e 's/<member>/\'$'\n<member>/g' | grep responseCode | \
sed -e 's/<member><name>//g' -e 's/<\/name>//g' -e 's/<\/value>//g' -e 's/<\/member>//g'
..现在获得你真正想要的格式应该是微不足道的。
