Question

我正在读取文件，我想找到一个时间戳记值并将其替换为0，然后再将其输出到另一个文件。因此，我正在尝试搜索和替换此值TIME =“ 20180731.5622743” 对于文件中的类似内容 TIME =“ 00000000.0000000”

到目前为止，我有..

 public Bind() {
        return Excel.run(async (ctx) => {
            ctx.workbook.bindings.addFromNamedItem("Field1", "Range", "Field1");
            ctx.workbook.bindings.addFromNamedItem("Field2", "Range", "Field2");
	    ctx.workbook.bindings.addFromNamedItem("Field3", "Range", "Field3");
            ctx.workbook.bindings.addFromNamedItem("Field4", "Range", "Field4");
            ctx.workbook.bindings.addFromNamedItem("Field5", "Range", "Field5");
            ctx.workbook.bindings.addFromNamedItem("Field6", "Range", "Field6");
            ctx.workbook.bindings.addFromNamedItem("Field7", "Range", "Field7");
            ctx.workbook.bindings.addFromNamedItem("Field8", "Range", "Field8");
            ctx.workbook.bindings.addFromNamedItem("Field9", "Range", "Field9");
            ctx.workbook.bindings.addFromNamedItem("Field10", "Range", "Field10");

            return ctx.sync();
        }).catch(ErrorHandler);
    }

    public Get() {
        return Excel.run(async (ctx) => {
            var field1 = Office.context.document.settings.get("Field1");
            if (field1 === null) {
                field1 = await this.SelectField1();
            }

            return $.post({
                url: 'getUrl',
                data: { id: field1 }
            }).done(async (model) => {
                ctx.workbook.bindings.getItem("Field1").getRange().values = [[model.Field1]];
                ctx.workbook.bindings.getItem("Field2").getRange().values = [[model.Field2]];
                ctx.workbook.bindings.getItem("Field3").getRange().values = [[model.Field3]];
                ctx.workbook.bindings.getItem("Field4").getRange().values = [[model.Field4]];
                ctx.workbook.bindings.getItem("Field5").getRange().values = [[model.Field5]];
                ctx.workbook.bindings.getItem("Field6").getRange().values = [[model.Field6]];
                ctx.workbook.bindings.getItem("Field7").getRange().values = [[model.Field7]];
                ctx.workbook.bindings.getItem("Field8").getRange().values = [[model.Field8]];
                ctx.workbook.bindings.getItem("Field9").getRange().values = [[model.Field9]];
                ctx.workbook.bindings.getItem("Field10").getRange().values = [[model.Field10]];

                // Sync to update sheet in Excel
                await ctx.sync();
            });
        }).catch(ErrorHandler);
    }

搜索和替换仅部分起作用，因为该行包含其他我不想替换的时间戳。如果我包含要搜索和替换的全部内容，则引号似乎阻碍了搜索和替换的成功。例如。（

open(INPUT, $path) or die $!;
open(OUTPUT, ">$susex_path")  or die $!;

while(<INPUT>){
   $line =~ s/([0-9]+8.[0-9]+7)/000000.0000000/g;
   print OUTPUT $line;
   }
}
close(INPUT);    
close(OUTPUT);

非常感谢您的帮助

Answer 1

尝试使用正则表达式：(?<=TIME=")\d{8}\.\d{7}(?=")

Demo

Answer 2

尝试一下可能会更快

$line =~ s/TIME="[0-9]{8}\.[0-9]{7}"/TIME="00000000.0000000"/g

请注意，在问题注释中提到，您需要{8}和{7}而不是+8和+7，并且"在s///的任一侧都不是特殊的。

但是.很特殊，需要转义；另外，除非您想在正则表达式之外使用原始时间戳，否则就不需要( ... )

正则表达式与带引号的perl匹配
