使用 C# 中的 aspose.words 从 word 文档中提取 2 个字符串之间的文本

Question

I have a word document from which I need to extract a few lines of text. the text i need to extract can be found in between the two strings: “must haves” and “could haves”. Does anyone know what I should do to achieve this?

Answer 1

You can use IReplacingCallback to achieve what you need. For example see the following code:

Document doc = new Document(@"C:\temp\in.docx");
FindReplaceOptions opt = new FindReplaceOptions();
opt.ReplacingCallback = new MyReplacingCallback();
Regex regex = new Regex(@"\<mytag\>(.*?)\<\/mytag\>");
doc.Range.Replace(regex, "", opt);

private class MyReplacingCallback : IReplacingCallback
{
    public ReplaceAction Replacing(ReplacingArgs args)
    {
        Console.WriteLine(args.Match.Groups[1].Value);
        return ReplaceAction.Skip;
    }
}

use tika to extract text from docx... : https://www.nuget.org/packages/TikaOnDotNet.TextExtractor

var str = new TikaOnDotNet.TextExtraction.TextExtractor().Extract(@"C:\Users\Inconnu\Downloads\test.docx").Text;

            int pForm = str.IndexOf("must haves") + "must haves".Length;
            int pTo = str.LastIndexOf("could haves");

            string result = str.Substring(pForm, pTo - pForm);
