利用sed将xml报文转换为分隔符形式报文

原始xml文本如下

 <?xml version="1.0" encoding="utf-8"?>

现在需要将上述内容Transaction标签中的值转换为下面的分隔符格式

1|||2017-03-21T20:40:36|||110.00|||1|||曹庄|宿州|||1|04|3401|804|33|20170321204036|03|3401|1105|1|20170321182056||||||22|||6401|||1638220100098530|||宁B63222|||104|||2157.60|||2047.60||||||9439DAD2|||09|||0134000030BC|||0018002D||||||C4FE|||0000000200031918|||0001|||宁B63222|||

下面是我执行的操作步骤

1、替换换行符，将整个xml文件处理成一行文本，重定向到文本1中

cat ***.xml | tr "\n" " " > 1

结果如下

<?xml version="1.0" encoding="utf-8"?><Message> <Header> <Version>2000000</Version> <MessageClass>5</MessageClass> <MessageType>7</MessageType> <SenderId>9999999964020001</SenderId> <ReceiverId>9999999964011001</ReceiverId> <MessageId>3280260</MessageId> </Header> <Body ContentType="1"> <ClearTargetDate>2017-03-22</ClearTargetDate> <ServiceProviderId>9999999934030001</ServiceProviderId> <IssuerId>9999999964011001</IssuerId> <MessageId>406843026</MessageId> <Count>1</Count> <Amount>110.00</Amount> <Transaction> <TransId>1</TransId> <Time>2017-03-21T20:40:36</Time> <Fee>110.00</Fee> <Service> <ServiceType>1</ServiceType> <Description>曹庄|宿州</Description> <Detail>1|04|3401|804|33|20170321 204036|03|3401|1105|1|20170321182056</Detail> </Service> <ICCard> <CardType>22</CardType> <NetNo>6401</NetNo> <CardId>1638220100098530</CardId> <License>宁B63222</License> <TransNo>104</TransNo> <PreBalance>2157.60</PreBalance><PostBalance>2047.60</PostBalance> </ICCard> <Validation> <TAC>9439DAD2</TAC> <TransType>09</TransType> <TerminalNo>0134000030BC</TerminalNo> <TerminalTransNo>0018002D</TerminalTransNo> </Validation> <OBU> <NetNo>C4FE</NetNo> <OBUId>0000000200031918</OBUId> <OBEState>0001</OBEState> <License>宁B63222</License> </OBU> </Transaction> </Body> </Message>

2、去除空格

sed 's/ //g' 1 > 2

结果如下

<?xml version="1.0" encoding="utf-8"?><Message><Header><Version>2000000</Version><MessageClass>5</MessageClass><MessageType>7</MessageType><SenderId>9999999964020001</SenderId><ReceiverId>9999999964011001</ReceiverId><MessageId>3280260</MessageId></Header><BodyContentType="1"><ClearTargetDate>2017-03-22</ClearTargetDate><ServiceProviderId>9999999934030001</ServiceProviderId><IssuerId>9999999964011001</IssuerId><MessageId>406843026</MessageId><Count>1</Count><Amount>110.00</Amount><Transaction><TransId>1</TransId><Time>2017-03-21T20:40:36</Time><Fee>110.00</Fee><Service><ServiceType>1</ServiceType><Description>曹庄|宿州</Description><Detail>1|04|3401|804|33|20170321204036|03|3401|1105|1|20170321182056</Detail></Service><ICCard><CardType>22</CardType><NetNo>6401</NetNo><CardId>1638220100098530</CardId><License>宁B63222</License><TransNo>104</TransNo><PreBalance>2157.60</PreBalance><PostBalance>2047.60</PostBalance></ICCard><Validation><TAC>9439DAD2</TAC><TransType>09</TransType><TerminalNo>0134000030BC</TerminalNo><TerminalTransNo>0018002D</TerminalTransNo></Validation><OBU><NetNo>C4FE</NetNo><OBUId>0000000200031918</OBUId><OBEState>0001</OBEState><License>宁B63222</License></OBU></Transaction></Body></Message>

3、去除无用的头部和尾部xml，只保留Transaction标签中的内容

sed 's/.*<Transaction>//g;s/<\/OBU>.*<\/Message>//g' 2 > 3

结果如下

4、将闭合标签</***>替换为|||

sed 's/<\/[^>]*>/|||/g' 3 > 4

结果如下

<TransId>1|||<Time>2017-03-21T20:40:36|||<Fee>110.00|||<Service><ServiceType>1|||<Description>曹庄|宿州|||<Detail>1|04|3401|804|33|20170321204036|03|3401|1105|1|20170321182056||||||<ICCard><CardType>22|||<NetNo>6401|||<CardId>1638220100098530|||<License>宁B63222|||<TransNo>104|||<PreBalance>2157.60|||<PostBalance>2047.60||||||<Validation><TAC>9439DAD2|||<TransType>09|||<TerminalNo>0134000030BC|||<TerminalTransNo>0018002D||||||<OBU><NetNo>C4FE|||<OBUId>0000000200031918|||<OBEState>0001|||<License>宁B63222|||

5、将开始标签<***>去除

sed 's/<[^>]*>//g' 4 > 5

结果如下

1|||2017-03-21T20:40:36|||110.00|||1|||曹庄|宿州|||1|04|3401|804|33|20170321204036|03|3401|1105|1|20170321182056||||||22|||6401|||1638220100098530|||宁B63222|||104|||2157.60|||2047.60||||||9439DAD2|||09|||0134000030BC|||0018002D||||||C4FE|||0000000200031918|||0001|||宁B63222|||

到此大功告成

将所有标签整理在一起

cat ***.xml | tr "\n" " " > 1

sed 's/ //g;s/.*<Transaction>//g;s/<\/OBU>.*<\/Message>//g;s/<\/[^>]*>/|||/g;s/<[^>]*>//g' 1 > 2
