请教 sed 替换修改 xml 文件问题

sed -e '/^$/d' -e 's/<env-entry-value>\/path\/to\/solr_home<\/env-entry-value>/<env-entry-value>\/usr\/solr\/server\/solr<\/env-entry-value>/'

还可以更简洁一点

用 sed 操作 xml 纯粹找麻烦……
写个 python 能省一半时间还不容易出错。

为什么不用 vi 呢？

@uuspider 你那两个去掉 comments 的有点危险，万一前后有空格就匹配不上。
另外不用分 3 条，可以用分号（；）分开： sed -e 's/foo1/bar1/;s/foo2/bar2/;s/foo3/bar3/'

@rrfeng 的确可以用 shell 调用 python 操作，大好，谢谢！

@maskerTUI 因为要用 vagrant 自动生成集群，用 vim 就不方便了

@rrfeng 多谢，现在已经用 python re 搞定了

python <<EOF
import re
fpath = '/usr/tomcat/webapps/solr/WEB-INF/web.xml'
rep_str = '''
<env-entry>
<env-entry-name>solr/home</env-entry-name>
<env-entry-value>/usr/solr/server/solr</env-entry-value>
<env-entry-type>java.lang.String</env-entry-type>
</env-entry>
'''
with open(fpath) as f: text = f.read()
text = re.sub('', rep_str, text, flags=re.DOTALL)
with open(fpath, 'wb') as f: f.write(text)
EOF

用 python 就是让你别用 re ……

@rrfeng 那咋弄啊？

@tikazyq python 有处理 xml 的类库、模块

sed -i -e '/^$/ {

sed 最好解决了

为什么要螳臂挡车地飞正则处理 XML ……
