NPOI读取Docx文件查询字符串

— Posted in编程 — 3 min read

最近有个需求就是读取一堆word文档的内容，查找里面的内容并记录。

网上搜了一下NPOI可以读取docx文件。

前期准备

  • 通过Package Manager安装npoi
Install-Package NPOI
PowerShell

代码实现

<span role="button" tabindex="0" data-code="using NPOI.XWPF.UserModel; using System.Text.RegularExpressions; var filePath = "xxx.docx"; using (FileStream fs = File.OpenRead(filePath)) { XWPFDocument docx = new XWPFDocument(fs); try { SearchDocx(docx); } catch (Exception ex) { // 错误处理 Console.WriteLine(ex.StackTrace); } finally { // 关闭docx docx.Close(); } } /// <summary> /// 通过正则匹配文字 /// </summary> /// <param name="text"></param> /// <returns></returns> static Match GetMatch(string text) { var regex = new Regex(@"key\s(\S+)"); var match = regex.Match(text); return match; } /// <summary> /// 查询Docx文档 /// </summary> /// <param name="document"></param> static void SearchDocx(XWPFDocument document) { foreach (var paragraph in document.Paragraphs) { SearchParagraph(paragraph); } foreach (var table in document.Tables) { SearchTable(table); } } /// <summary> /// 查询段落 /// </summary> /// <param name="paragraph"></param> static void SearchParagraph(XWPFParagraph paragraph) { var text = paragraph.Text; var match = GetMatch(text); if (match.Success) { // 查询成功，这里可以添加自已的操作 // todo } } /// <summary> /// 查询表格 /// </summary> /// <param name="table">
using NPOI.XWPF.UserModel;
using System.Text.RegularExpressions;

var filePath = "xxx.docx";
using (FileStream fs = File.OpenRead(filePath))
{
    XWPFDocument docx = new XWPFDocument(fs);
    try
    {
        SearchDocx(docx);
    }
    catch (Exception ex)
    {
        // 错误处理
        Console.WriteLine(ex.StackTrace);
    }
    finally
    {
        // 关闭docx
        docx.Close();
    }
}
