问题
I have XML similar to this one:
<orders>
<orderCompleteRequestType>
<Head>
<Aufnr>11111</Aufnr>
</Head>
<Register>
<Id>180</Id>
<value1>11</value1>
<value2>22</value2>
</Register>
<Register>
<Id>181</Id>
<value1>3</value1>
<value2>43</value2>
</Register>
<Register>
<Id>160</Id>
<value1>5</value1>
<value2>25</value2>
</Register>
</orderCompleteRequestType>
<orderCompleteRequestType>
<Head>
<Aufnr>22222</Aufnr>
</Head>
<Register>
<Id>280</Id>
<value1>1</value1>
<value2>12</value2>
</Register>
<Register>
<Id>160</Id>
<value1>12</value1>
<value2>7</value2>
</Register>
<Register>
<Id>281</Id>
<value1>94</value1>
<value2>22</value2>
</Register>
</orderCompleteRequestType>
</orders>
I want to select in CSV format some values from each "orderCompleteRequestType" structure:
- Head/Aufrn
- Register/Id
- Register/value1
- Register/value2
When using following command line:
xmlstarlet sel -T -t -m "/orders/orderCompleteRequestType" -v "Head/Aufnr" -o ";" -v "Register/Id" -o ";" -v "Register/value1" -o ";" -v "Register/value2" -n -n test.xml
I get:
11111;180
181
160;11
3
5;22
43
25
22222;280
160
281;1
12
94;12
7
22
so, first goes all values of Register/Id nodes, next all Register/value1's and finally all Register/value2's, but rather of this I expect something like:
11111;180;11;22
11111;181;3;43
11111;160;5;25
22222;280;1;12
22222;160;12;7
22222;281;94;22
Can anyone help me, because my brain rejecting to do work...
回答1:
Instead of matching orderCompleteRequestType, consider matching Register instead...
xmlstarlet sel -T -t -m "/orders/orderCompleteRequestType/Register" -v "concat(../Head/Aufnr,';',Id,';',value1,';',value2)" -n test.xml
output...
11111;180;11;22
11111;181;3;43
11111;160;5;25
22222;280;1;12
22222;160;12;7
22222;281;94;22
There isn't an extra newline between each orderCompleteRequestType, but maybe that's not a big deal? If it is, it might be easier to just write an XSLT and call that with xmlstarlet.
