linux + 如何從 xml 文件中擷取值

我想從此 xml 文件中擷取所有值並將文件中的值列印為 out1.txt

備註 - 來自 xml 的值表示雙括號中的單詞

 more input.txt

<app name="UAT/ECC/Global/MES/1206/MRP-S23"   ear="UAT/ECC/Global/MES/1206/MRP-S23.ear" xml="UAT/ECC/Glal/ME/120/MRP-  S23.xml"/>
<app name="OQ/ediedbn/adSFSF/adSFSF-CL" ear="OQ/ebn/aSF/adSF- CL.ear"  xml="OQ/ediedbn/adSFSF/adSSF-CL.xml"/>
<app name="OQ/ediedbn/adaEBS/adOrBS-HR-CL"  ear="OQ/ediedbn/adOraS/araEBS- HR-CL.ear" xml="OQ/eddbn/aOraEBS/adOEBS-   HR-CL.xml"/>
<app name="UAT/CZ/LIMS/T068_01/LIMS-QA-S03" ear="UAT/CZ/LIS/T068_01/LIS-QA-     .ear" xml="UAT/CZ/LIMS/T068_01/LIMS-QA-S03.xml"/>

請建議如何使用 awk / perl one liner bash 擷取 out1.txt 文件中的值

您可以像這樣使用 awk 對輸入文件進行切片：

gv@debian:$ cat a.txt
<app name="UAT/ECC/Global/MES/1206/MRP-S23"   ear="UAT/ECC/Global/MES/1206/MRP-S23.ear" xml="UAT/ECC/Glal/ME/120/MRP-  S23.xml"/>
<app name="OQ/ediedbn/adSFSF/adSFSF-CL" ear="OQ/ebn/aSF/adSF- CL.ear"  xml="OQ/ediedbn/adSFSF/adSSF-CL.xml"/>
<app name="OQ/ediedbn/adaEBS/adOrBS-HR-CL"  ear="OQ/ediedbn/adOraS/araEBS- HR-CL.ear" xml="OQ/eddbn/aOraEBS/adOEBS-   HR-CL.xml"/>
<app name="UAT/CZ/LIMS/T068_01/LIMS-QA-S03" ear="UAT/CZ/LIS/T068_01/LIS-QA-     .ear" xml="UAT/CZ/LIMS/T068_01/LIMS-QA-S03.xml"/>

gv@debian:$ cat b.txt

gv@debian:$ awk -F"name=|ear=|xml=|/>" '{print $2} {print $4}' a.txt >b.txt

gv@debian:$ cat b.txt
"UAT/ECC/Global/MES/1206/MRP-S23"   
"UAT/ECC/Glal/ME/120/MRP-  S23.xml"
"OQ/ediedbn/adSFSF/adSFSF-CL" 
"OQ/ediedbn/adSFSF/adSSF-CL.xml"
"OQ/ediedbn/adaEBS/adOrBS-HR-CL"  
"OQ/eddbn/aOraEBS/adOEBS-   HR-CL.xml"
"UAT/CZ/LIMS/T068_01/LIMS-QA-S03" 
"UAT/CZ/LIMS/T068_01/LIMS-QA-S03.xml"

如果您不想保留雙引號，可以使用 sed 將它們刪除，如下所示：

gv@debian:$ sed -i 's/\"//g' b.txt
gv@debian:$ cat b.txt
UAT/ECC/Global/MES/1206/MRP-S23   
UAT/ECC/Glal/ME/120/MRP-  S23.xml
OQ/ediedbn/adSFSF/adSFSF-CL 
OQ/ediedbn/adSFSF/adSSF-CL.xml
OQ/ediedbn/adaEBS/adOrBS-HR-CL  
OQ/eddbn/aOraEBS/adOEBS-   HR-CL.xml
UAT/CZ/LIMS/T068_01/LIMS-QA-S03 
UAT/CZ/LIMS/T068_01/LIMS-QA-S03.xml

或者在一個襯里中，將 awk 管道傳輸到 sed ：

gv@debian:$ awk -F"name=|ear=|xml=|/>" '{print $2} {print $4}' a.txt |sed 's/\"//g' >b.txt

提示：如果您希望每個輸入文件行的所有欄位都寫入輸出文件中的一行，請使用{print $2 $4}（將欄位放在相同的括號內）。

此 awk 方法起作用的關鍵是 awk 可以接受多字元定界符以及由 | 分隔的多個定界符。(=或) 。

awk 分隔符由選項 -F 定義

如果您需要保存耳朵值，請將 {print $4} 替換為 {print $3}。

要了解有關此 awk 切片的資訊，請查看將由 awk 分隔的所有欄位：

$ awk -F"name=|ear=|xml=|/>" '{print "Field1="$1} {print "Field2="$2} {print "Field3="$3} {print "Field4="$4}' a.txt
Field1=<app 
Field2="UAT/ECC/Global/MES/1206/MRP-S23"   
Field3="UAT/ECC/Global/MES/1206/MRP-S23.ear" 
Field4="UAT/ECC/Glal/ME/120/MRP-  S23.xml"
Field1=<app 
Field2="OQ/ediedbn/adSFSF/adSFSF-CL" 
Field3="OQ/ebn/aSF/adSF- CL.ear"  
Field4="OQ/ediedbn/adSFSF/adSSF-CL.xml"
Field1=<app 
Field2="OQ/ediedbn/adaEBS/adOrBS-HR-CL"  
Field3="OQ/ediedbn/adOraS/araEBS- HR-CL.ear" 
Field4="OQ/eddbn/aOraEBS/adOEBS-   HR-CL.xml"
Field1=<app 
Field2="UAT/CZ/LIMS/T068_01/LIMS-QA-S03" 
Field3="UAT/CZ/LIS/T068_01/LIS-QA-     .ear" 
Field4="UAT/CZ/LIMS/T068_01/LIMS-QA-S03.xml"
