python docx刪除word段落

使用python-docx編輯一個docx文檔時, 對添加的方法使用很多, 但有時候也會用到刪除和修改

python-docx中並沒有提供delete()方法, github上給出瞭解決方法:

https://github.com/python-openxml/python-docx/issues/33

def delete_paragraph(paragraph):
    p = paragraph._element
    p.getparent().remove(p)
    # p._p = p._element = None
    paragraph._p = paragraph._element = None

經試驗, 此方法對刪除段落,表格,標題, 圖片都是管用的: 

from docx import Document
docx = Document('word_file.docx')
def delete_docx_prefix_description(docx):
    delete_paragraph(docx.tables[0]) # 刪除word中第一個table
    for p in docx.paragraphs:
        delete_paragraph(p)
        if ''.join(p.text.split(' ')).lower()=='header_keyword':
            break
    for p in docx.paragraphs:  
        if p.text.lower()=='': # 刪除word中在開始部分的空白段落
            delete_paragraph(p)
        else:
            break
