Office Oxide

提取表格

Office Oxide 把表格当作 IR 一等元素：DOCX 中的每一个 <w:tbl>、XLSX 中的每一个区间、PPTX 中的每一个 <a:tbl> 都会以带类型的 Table { rows: [[单元格, ...]] } 形式回来。一个循环处理三种格式。

遍历文档里的全部表格

Python

from office_oxide import Document

with Document.open("report.docx") as doc:
    ir = doc.to_ir()

for section in ir["sections"]:
    for el in section["elements"]:
        if el["kind"] == "Table":
            for row in el["rows"]:
                print(row)

Rust

use office_oxide::Document;
use office_oxide::ir::Element;

let doc = Document::open("report.docx")?;
let ir = doc.to_ir();

for section in &ir.sections {
    for el in &section.elements {
        if let Element::Table(t) = el {
            for row in &t.rows {
                println!("{row:?}");
            }
        }
    }
}

JavaScript

using doc = Document.open('report.docx');
const ir = doc.toIr();

for (const section of ir.sections) {
  for (const el of section.elements) {
    if (el.kind === 'Table') {
      for (const row of el.rows) {
        console.log(row);
      }
    }
  }
}

Go

doc, err := officeoxide.Open("report.docx")
if err != nil { log.Fatal(err) }
defer doc.Close()

irJSON, _ := doc.ToIRJSON()
var ir struct {
    Sections []struct {
        Elements []struct {
            Kind string     `json:"kind"`
            Rows [][]string `json:"rows"`
        } `json:"elements"`
    } `json:"sections"`
}
json.Unmarshal([]byte(irJSON), &ir)

for _, section := range ir.Sections {
    for _, el := range section.Elements {
        if el.Kind == "Table" {
            for _, row := range el.Rows {
                fmt.Println(row)
            }
        }
    }
}

C#

using OfficeOxide;
using System.Text.Json;

using var doc = Document.Open("report.docx");
using var ir = JsonDocument.Parse(doc.ToIrJson());

foreach (var section in ir.RootElement.GetProperty("sections").EnumerateArray())
{
    foreach (var el in section.GetProperty("elements").EnumerateArray())
    {
        if (el.GetProperty("kind").GetString() != "Table") continue;
        foreach (var row in el.GetProperty("rows").EnumerateArray())
        {
            Console.WriteLine(string.Join(" | ", row.EnumerateArray().Select(c => c.GetString())));
        }
    }
}

XLSX：每个工作表区间一张表

对电子表格来说，每个 section 对应一个工作表，表格对应检测到的使用区间。空单元格输出空字符串；合并单元格展开为左上角值，其余位置留空。

Python

import csv
from office_oxide import Document

with Document.open("budget.xlsx") as doc:
    ir = doc.to_ir()

for section in ir["sections"]:
    sheet_name = section.get("title", "Sheet")
    out_path = f"{sheet_name}.csv"
    with open(out_path, "w", newline="") as f:
        w = csv.writer(f)
        for el in section["elements"]:
            if el["kind"] == "Table":
                for row in el["rows"]:
                    w.writerow(row)

需要更细粒度的单元格访问（公式、合并、命名区域）时，转用格式特有 API:

with Document.open("budget.xlsx") as doc:
    xlsx = doc.as_xlsx()
    for sheet in xlsx.sheets():
        print(sheet.name(), sheet.dimensions())

DOCX：表格与段落交错

IR 保留段落和表格的源顺序，因此可以还原文章流:

from office_oxide import Document

with Document.open("report.docx") as doc:
    ir = doc.to_ir()

for section in ir["sections"]:
    for el in section["elements"]:
        if el["kind"] == "Heading":
            print(f"\n## {el['text']}")
        elif el["kind"] == "Paragraph":
            print(" ".join(r["text"] for r in el["runs"]))
        elif el["kind"] == "Table":
            for row in el["rows"]:
                print("|", " | ".join(row), "|")

PPTX：表格在幻灯片 section 里

每张幻灯片是独立 section。逐个 section 迭代以恢复幻灯片级别的上下文:

with Document.open("deck.pptx") as doc:
    ir = doc.to_ir()

for i, section in enumerate(ir["sections"], 1):
    for el in section["elements"]:
        if el["kind"] == "Table":
            print(f"幻灯片 {i}: {len(el['rows'])}×{len(el['rows'][0])} 表")

需要单元格类型而不是字符串时

IR 中的表格把单元格扁平化成字符串。要在 XLSX 中区分数字、文本、布尔，请用格式特有的访问器:

with Document.open("budget.xlsx") as doc:
    xlsx = doc.as_xlsx()
    for sheet in xlsx.sheets():
        for cell in sheet.cells():
            print(cell.address(), cell.value(), cell.value_type())
