我试图提取使用文本段落匹配部正则表达式stringr-文本之一是匹配R中
if returnValue is not null then
1. if instrument type is "Bond" then
Status is equals to 138 if the instrument is sensible coupon,
coupon type is not null and not equals to "ZERO COUPON" and previous value
is not equals to current value, and iinstrument creation date is not D
- Status is equals to 137 if the instrument is sensible bbg, previous value
is not equals to current value, and iinstrument creation date is not D or D-1
- Status is equals to the previous status if the value is not manual
and previous status is 138, or 137
2. if attribute SEC_PAYT_DTE is not null then
if attribute SEC_PAYT_DTE (typed as date) is fresher than
returnValue (typed as date) then
set status to 136 that is "Functional Error"
3. if acrual date (DEBT_STRT_ACRL_DTE) is not null and instrument
category is "Structured Product", and acrual date is different
frorm return value then
set status to 150 that is "Non blocking functional error".
我想提取什么是“状态138”,“137状态” ,'状态136','状态150'。我做的是str_extract_all(x,'(S | s)tatus [a-z \ s] {1,10} [0-9] {1,3} [^ \。'')。但它不起作用。
这里有什么规则?请明确定义你想要正则表达式做什么 – 2014-10-27 20:37:11
我希望正则表达式能够找到字符串的'S(s)status'+ 0-3位数字。例如'状态等于138',则正则表达式应该找到138.然而,'不是D或D-1'中的1不应该返回 – 2014-10-27 20:44:25
那么该行和前一状态应该是138还是137返回? – 2014-10-27 20:56:06
