I need to get a specific piece of a .txt file that is between <tag> and </tag> .
But I need to get all the lines where it happens.
Example:
<tag1>titulo</tag1>
<tag2>subtitulo</tag2>
texto...
<tag2>subtitulo</tag2>
texto...
<tag1>titulo</tag1>
<tag2>subtitulo</tag2>
texto...
I want to get the text between these tags and save.
Try this code:
var pattern = /<tag.*?>(.*?)<\/tag.*?>/g; //Padrão que a regex vai dar Match
var reader = new FileReader(); //Leitor do arquivo txt
var output = ""; //Variável de texto onde será carregado o conteúdo do txt
reader.onload = function (e) { //Função para leitura após o carregamento do reader
output = e.target.result;
displayContents(output);
}; //Fim da função
reader.readAsText(filePath.files[0]); //insira o path para seu txt
var m;
do {
m = pattern.exec(output); //executa o padrão da regex e armazena os val em m
if (m) {
console.log(m[1]); //mostra o resultado no console do browser
}
} while (m);
Explanation of the code:
The following function loads the txt file through a FileReader
Pass your content to the output variable.
Prints content that matches the regex in the browser console.
Explanation of regex:
/<tag.*?>(.*?)<\/tag.*?>/g;
<tag Finds the sequence exactly equal to <tag
.*?> Proceeds (not captured) by all characters up to the first occurrence of > . (.*?)<\/tag Captures all content in capture group 1 until the first occurrence of </tag
.*?> Proceeds (not captured) by all characters up to the first occurrence of > . /g It is a regex modifier, indicates that it should continue trying to match until the end of the text sequence.
