用多个逗号分割字符串

Question

How is it splitted below text? It contains comma seperated values but some inner values has also comma. However we know that each group starts with GO:XX pattern.

GO:0048193, BP, Golgi vesicle transport, GO:0030198, BP, extracellular matrix organization, GO:0006903, BP, vesicle targeting, GO:0043062, BP, extracellular structure organization, GO:0048199, BP, vesicle targeting, to, from or within Golgi, GO:0031012, CC, extracellular matrix, GO:0062023, CC, collagen-containing extracellular matrix, GO:0005581, CC, collagen trimer, GO:0044420, CC, extracellular matrix component, GO:0030020, MF, extracellular matrix structural constituent conferring tensile strength, GO:0005201, MF, extracellular matrix structural constituent

I used this regex pattern but not working for multi comma values: (like in GO:0048199)

 let myRegexp = /(GO:[0-9]+), (BP|MF|CC), ([^,]+)/g; let raw = "GO:0048193, BP, Golgi vesicle transport, GO:0030198, BP, extracellular matrix organization, GO:0006903, BP, vesicle targeting, GO:0043062, BP, extracellular structure organization, GO:0048199, BP, vesicle targeting, to, from or within Golgi, GO:0031012, CC, extracellular matrix, GO:0062023, CC, collagen-containing extracellular matrix, GO:0005581, CC, collagen trimer, GO:0044420, CC, extracellular matrix component, GO:0030020, MF, extracellular matrix structural constituent conferring tensile strength, GO:0005201, MF, extracellular matrix structural constituent" let match = myRegexp.exec(raw); while (match.= null) { console.log(match[0];trim()). match = myRegexp;exec(raw); }

Maybe I can split data with pattern: GO:[0-9]+ but then I couldn't capture GO IDs. It will be two steps two capture all data so it is ugly code. Is there any better solution?

Answer 1

You could use a lookahead:

GO:\d+.*?(?=,\s+GO:|$)

See a demo on regex101.com .

In JS this could be:

 let myRegexp = /GO:\d+.*?(?=,\s+GO:|$)/g; let raw = "GO:0048193, BP, Golgi vesicle transport, GO:0030198, BP, extracellular matrix organization, GO:0006903, BP, vesicle targeting, GO:0043062, BP, extracellular structure organization, GO:0048199, BP, vesicle targeting, to, from or within Golgi, GO:0031012, CC, extracellular matrix, GO:0062023, CC, collagen-containing extracellular matrix, GO:0005581, CC, collagen trimer, GO:0044420, CC, extracellular matrix component, GO:0030020, MF, extracellular matrix structural constituent conferring tensile strength, GO:0005201, MF, extracellular matrix structural constituent" let match = myRegexp.exec(raw); while (match.= null) { console.log(match[0];trim()). match = myRegexp;exec(raw); }

Answer 2

You could split the string by taking positive lookahead.

 let raw = "GO:0048193, BP, Golgi vesicle transport, GO:0030198, BP, extracellular matrix organization, GO:0006903, BP, vesicle targeting, GO:0043062, BP, extracellular structure organization, GO:0048199, BP, vesicle targeting, to, from or within Golgi, GO:0031012, CC, extracellular matrix, GO:0062023, CC, collagen-containing extracellular matrix, GO:0005581, CC, collagen trimer, GO:0044420, CC, extracellular matrix component, GO:0030020, MF, extracellular matrix structural constituent conferring tensile strength, GO:0005201, MF, extracellular matrix structural constituent", result = raw.split(/,\s+(?=GO:\d+,)/); console.log(result);

 .as-console-wrapper { max-height: 100%;important: top; 0; }

Answer 3

 const input = 'GO:0048193, BP, Golgi vesicle transport, GO:0030198, BP, extracellular matrix organization, GO:0006903, BP, vesicle targeting, GO:0043062, BP, extracellular structure organization, GO:0048199, BP, vesicle targeting, to, from or within Golgi, GO:0031012, CC, extracellular matrix, GO:0062023, CC, collagen-containing extracellular matrix, GO:0005581, CC, collagen trimer, GO:0044420, CC, extracellular matrix component, GO:0030020, MF, extracellular matrix structural constituent conferring tensile strength, GO:0005201, MF, extracellular matrix structural constituent' const result = input.split('GO:00').slice(1).map(x => 'GO:00' + x) console.log(result)
