使用python-pptx提取PPT文本时部分内容丢失的问题求助

导致文本未被提取的常见原因是目标文本位于分组形状（Group Shape）或表格单元格中，原代码仅遍历了幻灯片的顶层形状，未处理嵌套结构的内容，而这些内容在XML中是存在的。以下是针对性的解决方案：

1. 处理分组形状的递归提取 #

修改代码，增加对分组形状的递归遍历，深入提取内部子形状的文本：

from pptx import Presentation

def extract_text_from_shape(shape, text_runs):
    # 递归处理分组形状（MsoShapeType.GROUP对应数值6）
    if shape.shape_type == 6:
        for sub_shape in shape.shapes:
            extract_text_from_shape(sub_shape, text_runs)
        return
    # 提取普通文本框内容
    if not shape.has_text_frame:
        return
    for paragraph in shape.text_frame.paragraphs:
        for run in paragraph.runs:
            if run.text.strip():  # 可选：过滤空白文本
                text_runs.append(run.text)

def getPptContent(path):
    prs = Presentation(path)
    text_runs = []
    for slide in prs.slides:
        for shape in slide.shapes:
            extract_text_from_shape(shape, text_runs)
    return text_runs

2. 额外处理表格内的文本 #

如果丢失的文本位于表格中，在上述基础上添加表格处理逻辑：

from pptx import Presentation

def extract_text_from_shape(shape, text_runs):
    # 递归处理分组形状
    if shape.shape_type == 6:
        for sub_shape in shape.shapes:
            extract_text_from_shape(sub_shape, text_runs)
        return
    # 提取表格单元格内的文本
    if shape.has_table:
        for row in shape.table.rows:
            for cell in row.cells:
                for paragraph in cell.text_frame.paragraphs:
                    for run in paragraph.runs:
                        if run.text.strip():
                            text_runs.append(run.text)
        return
    # 提取普通文本框内容
    if not shape.has_text_frame:
        return
    for paragraph in shape.text_frame.paragraphs:
        for run in paragraph.runs:
            if run.text.strip():
                text_runs.append(run.text)

def getPptContent(path):
    prs = Presentation(path)
    text_runs = []
    for slide in prs.slides:
        for shape in slide.shapes:
            extract_text_from_shape(shape, text_runs)
    return text_runs

上述代码覆盖了绝大多数文本丢失的场景，通过递归遍历嵌套形状和表格结构，能完整提取XML中存在的所有文本内容。
