如何使用linux csplit来切割大量的XML文件？

示例文件:(注意：通常每个“列表”xml节点应该在它自己的行上)

<?xml version="1.0" encoding="UTF-8"?>
<lisTings>
<lisTing><date>2009-09-22</date><desc>This is a description WITHOUT line breaks and works fine with split</desc><more_tags>stuff</more_tags></lisTing>
<lisTing><date>2009-09-22</date><desc>This is a really
Annoying description field
WITH line breaks 
that screw the split function</desc><more_tags>stuff</more_tags></lisTing>
</lisTings>

然后有时我的分裂最终会像

<?xml version="1.0" encoding="UTF-8"?>
<lisTings>
<lisTing><date>2009-09-22</date><desc>This is a description WITHOUT line breaks and works fine with split</desc><more_tags>stuff</more_tags></lisTing>
<lisTing><date>2009-09-22</date><desc>This is a really
Annoying description field
WITH line breaks ... 
EOF

所以 – 我一直在阅读“csplit”,听起来它可能有助于解决这个问题.我似乎无法正确表达正确的表达……

基本上我想要〜50ish文件的相同输出

就像是：

*csplit -k myfile.xml '/</lisTing>/' 25000 {50}

任何帮助都会很棒
谢谢！
