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代码实现
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"></param>
static void SearchTable(XWPFTable table)
{
foreach (var row in table.Rows)
{
foreach (var cell in row.GetTableCells())
{
if (cell.Paragraphs.Any())
{
foreach (var p in cell.Paragraphs)
{
SearchParagraph(p);
}
}
if (cell.Tables.Any())
{
foreach (var t in cell.Tables)
{
SearchTable(t);
}
}
var text = table.Text;
var match = GetMatch(text);
if (match.Success)
{
// 查询成功，这里可以添加自已的操作
// todo
}
}
}
}
