shell对xml文件操作（更新属性值+以当前日期重命名）

xml示例文件

本文代码将以下面文件名为Crm运行信息_20190222103001.xml 的文件为例做说明。

<?xml version="1.0" encoding="UTF-8"?>
<!-- Base_station_ICT -->
<CrmRunningInfoRecordList>
<CrmRunningInfoRecord>
 <CRMNETUNIT>5</CRMNETUNIT>
 <RLSETUPNUM>1633</RLSETUPNUM>
 <JQRLSETUPNUM>2388</JQRLSETUPNUM>
 <RLSETUPSUCCESSNUM>601</RLSETUPSUCCESSNUM>
 <RLSETUPFAILNUM>1032</RLSETUPFAILNUM>
 <JQRLSETUPSUCCESSNUM>1426</JQRLSETUPSUCCESSNUM>
 <JQRLSETUPFAILNUM>962</JQRLSETUPFAILNUM>
 <REPORTTIME>2019-01-10 14:30:01</REPORTTIME>
</CrmRunningInfoRecord>
</CrmRunningInfoRecordList>

该文件所属目录为 /home/perf/perf_files/models/

修改xml文件的shell脚本

#!/bin/sh

change_CRM_precent()
{
		# 找出当前Crm运行信息_*.xml文件存放的绝对路径
		# 【例】输出/home/perf/perf_files/models/CRM运行信息_20190222103001.xml
        CrmFile=$(ls /home/perf/perf_files/models/Crm运行信息_*.xml)

        # sed -i "/旧值/c \新值" 文件路径

#  ls ${ModelPath}DPU*.xml【输出】/home/perf/perf_files/models/DPU流量统计_20190222103001.xml

# 正则匹配项
# 4个字符是0-9的数字-2个字符是0-9的数字 2个字符是0-9的数字：2个字符是0-9的数字：2个字符是0-9的数字
RE="[0-9]\{4\}-[0-9]\{2\}-[0-9]\{2\} [0-9]\{2\}:[0-9]\{2\}:[0-9]\{2\}"

# 给各xml按照日期尾缀命名
sed -i "s/$RE/$TT/g" ${ModelPath}*.xml 
rename "$OldTime" "$CurTime" ${ModelPath}*.xml
cp ${ModelPath}*.xml $FilePath

echo "End ./change_models.sh to modify xml!"

代码中的几个关键点

1. shell的模糊匹配 *： ls /home/perf/perf_files/models/Crm运行信息_*.xml
2. 更改xml属性值 grep、awk： RLSuccSum=$(cat &quot;$CrmFile" | grep “” |awk -F “>” ‘{print $2}’ |awk -F “<” ‘{print $1}’)
3. 直接修改读取的文件内容 sed -i： sed -i “/原字符串/c \新字符串” 文件路径
4. cut -b 是以字节分割，其中中文字符占4个字节，英文字符占1个字节
5. 字符串变量分割： ${CurTime:0:8}
6. 给各xml按照日期尾缀命名：

OldTime=$(ls ${ModelPath}DPU*.xml | cut -b 46-59)
CurTime=$(date "+%Y%m%d%H%M%S")

sed -i "s/$RE/$TT/g" ${ModelPath}*.xml 
rename "$OldTime" "$CurTime" ${ModelPath}*.xml
cp ${ModelPath}*.xml $FilePath
