例子:
“100磅”
“我觉得173磅”
“73磅”
我正在寻找一种干净的方法来提取这些字符串中的数字数据.
这是我目前正在做的以剥离回应:
def stripResponse(String response) { if(response) { def toRemove = ["lbs.","lbs","pounds.","pounds"," "] def toMod = response for(remove in toRemove) { toMod = toMod?.replaceAll(remove,"") } return toMod }}解决方法 您可以使用findAll然后将结果转换为整数: def extractInts( String input ) { input.findAll( /\d+/ )*.toInteger()}assert extractInts( "100 pounds is 23" ) == [ 100,23 ]assert extractInts( "I think 173 lbs" ) == [ 173 ]assert extractInts( "73 lbs." ) == [ 73 ]assert extractInts( "No numbers here" ) == []assert extractInts( "23.5 only ints" ) == [ 23,5 ]assert extractInts( "positive only -13" ) == [ 13 ] 如果您需要小数和负数,则可能使用更复杂的正则表达式:
def extractInts( String input ) { input.findAll( /-?\d+\.\d*|-?\d*\.\d+|-?\d+/ )*.todouble()}assert extractInts( "100 pounds is 23" ) == [ 100,23 ]assert extractInts( "I think 173 lbs" ) == [ 173 ]assert extractInts( "73 lbs." ) == [ 73 ]assert extractInts( "No numbers here" ) == []assert extractInts( "23.5 handles float" ) == [ 23.5 ]assert extractInts( "and negatives -13" ) == [ -13 ] 总结 以上是内存溢出为你收集整理的从groovy中的字符串中提取数字数据全部内容,希望文章能够帮你解决从groovy中的字符串中提取数字数据所遇到的程序开发问题。
