正则表达式匹配和分组直到一个字符序列

标签: javascript regex

我有一个包含多个关键字的字符串,这些关键字的值之间用冒号(或空格)分隔。关键字和值对本身仅由空格分隔(或根本没有分隔)。

一些例子是:

"TAG1: asd asd testTAG2:TEST"
"TAG1:asd asd test TAG2:TEST"
"TAG1: asd asd test TAG2:TEST TAG1:hello"

然后,我要使用此正则表达式来匹配(TAG1|TAG2): ?(.+),它仅在我具有单个标记对时才有效。因此,我尝试使用正向前行((TAG1|TAG2): ?(.+)(?=TAG1|TAG2))进行匹配,直到下一次出现为止,但是如果我有一对,显然这是行不通的,如果我有两个以上的对,这也将不起作用。

所以我想知道的是如何将其拆分为多个匹配项,然后为标记名分配一个组,为值分配另一个组:

"TAG1: asd asd testTAG2:TEST"
[["TAG1", "asd asd test"], ["TAG2", "TEST"]]

"TAG1:asd asd test TAG2:TEST"
[["TAG1", "asd asd test"], ["TAG2", "TEST"]]

"TAG1: asd asd test TAG2:TEST TAG1:hello"
[["TAG1", "asd asd test"], ["TAG2", "TEST"], ["TAG1", "hello"]]

除了将其包含在比赛中之外,还有什么替代前瞻的方式?我认为这是问题所在,因为它随后跳过了下一个标签。

我们可以尝试使用两次正则表达式拆分,一次是获取所有标签及其值的数组,第二次是填充2D数组。

// Import the Image EXIF Orientation and Image Preview plugins
import FilePondPluginImageExifOrientation from 'filepond-plugin-image-exif-orientation'
import FilePondPluginImagePreview from 'filepond-plugin-image-preview'
import 'filepond-plugin-image-preview/dist/filepond-plugin-image-preview.css'

// Register the plugins
registerPlugin(FilePondPluginImageExifOrientation, FilePondPluginImagePreview)

function App() {
  console.log('TEST');
  const [files, setFiles] = useState([])
  console.log(files);
  return (
    <div className="App">
      <FilePond
        server='/api'
        files={files}
        allowMultiple={true}
        onupdatefiles={setFiles}
        labelIdle='Drag & Drop your files or <span class="filepond--label-action">Browse</span>'
      />
    </div>
  )
}

const rootElement = document.getElementById('root')
ReactDOM.render(<App />, rootElement)

我将使用拆分方法:
