Question

它是如何在文本下方拆分的？它包含逗号分隔的值，但一些内部值也有逗号。但是我们知道每个组都以 GO:XX 模式开头。

<块引用>

GO:0048193, BP, 高尔基体囊泡运输, GO:0030198, BP, 细胞外矩阵组织，GO：0006903，BP，囊泡靶向，GO：0043062， BP，细胞外结构组织，GO:0048199，BP，囊泡以高尔基体为目标、从高尔基体或在高尔基体内部， GO:0031012，CC，细胞外基质，GO：0062023，CC，含胶原的细胞外基质， GO:0005581, CC, 胶原三聚体, GO:0044420, CC, 细胞外基质组分, GO:0030020, MF, 细胞外基质结构成分赋予抗张强度，GO：0005201，MF，细胞外基质结构成分

我使用了这个正则表达式模式，但不适用于多逗号值：（如 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);
}

也许我可以用模式分割数据：GO:[0-9]+ 但我无法捕获 GO ID。这将是两步两捕获所有数据，所以它是丑陋的代码。有没有更好的解决办法？

Answer 1

您可以使用前瞻：

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

见a demo on regex101.com。

在 JS 中，这可能是：

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

您可以通过正向预测来拆分字符串。

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);

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)

用多逗号分割字符串
