我的 PowerPoint 幻灯片由文本框组成,有时位于组形状内。从这些数据中提取数据时,文本不是按顺序提取的。 有时先提取ppt末尾的文本框,有时先提取中间的文本框等等。
以下代码从文本框中获取文本并处理组对象。
for eachfile in files:
prs = Presentation(eachfile)
textrun=[]
# ---Only on text-boxes outside group elements---
for slide in prs.slides:
for shape in slide.shapes:
if hasattr(shape, "text"):
print(shape.text)
textrun.append(shape.text)
# ---Only operate on group shapes---
group_shapes = [shp for shp in slide.shapes
if shp.shape_type ==MSO_SHAPE_TYPE.GROUP]
for group_shape in group_shapes:
for shape in group_shape.shapes:
if shape.has_text_frame:
print(shape.text)
textrun.append(shape.text)
new_list=" ".join(textrun)
text_list.append(new_list)
print(text_list)
我想根据幻灯片中出现的顺序过滤提取的一些数据。 函数根据什么决定顺序? 应该怎么做才能解决这个问题?
史蒂夫的评论非常正确;返回的形状:
for shape in slide.shapes:
...
按照底层 XML 的文档顺序 ,这也是建立 z-order 的原因。 Z 顺序是“堆叠”顺序,就好像每个形状都在单独的透明片(层)上,第一个返回的形状位于底部,每个后续形状添加到堆栈的顶部(并重叠其下方的任何形状) .
我认为你在这里追求的是从左到右、从上到下的顺序。您需要编写自己的代码,使用
shape.left
和 shape.top
按此顺序对形状进行排序。
这样的事情可能会成功:
def iter_textframed_shapes(shapes):
"""Generate shape objects in *shapes* that can contain text.
Shape objects are generated in document order (z-order), bottom to top.
"""
for shape in shapes:
# ---recurse on group shapes---
if shape.shape_type == MSO_SHAPE_TYPE.GROUP:
group_shape = shape
for shape in iter_textframed_shapes(group_shape.shapes):
yield shape
continue
# ---otherwise, treat shape as a "leaf" shape---
if shape.has_text_frame:
yield shape
textable_shapes = list(iter_textframed_shapes(slide.shapes))
ordered_textable_shapes = sorted(
textable_shapes, key=lambda shape: (shape.top, shape.left)
)
for shape in ordered_textable_shapes:
print(shape.text)
