以下是一个使用Python和PyPDF2库编写的脚本示例，用于计算PDF中包含特定文本的文本框的总数：

import PyPDF2

def count_text_boxes_with_text(pdf_path, target_text):
    text_box_count = 0

    with open(pdf_path, 'rb') as file:
        pdf = PyPDF2.PdfFileReader(file)
        num_pages = pdf.getNumPages()

        for page_num in range(num_pages):
            page = pdf.getPage(page_num)
            annotations = page['/Annots']
            if annotations:
                for annotation in annotations:
                    if annotation['/Subtype'] == '/Widget' and annotation.get('/V'):
                        if target_text in annotation['/V']:
                            text_box_count += 1
    return text_box_count

pdf_path = 'path/to/your/pdf.pdf'
target_text = 'your_target_text'

count = count_text_boxes_with_text(pdf_path, target_text)
print(f"Total text boxes with '{target_text}': {count}")

请确保已将PyPDF2库安装在您的Python环境中，可以使用pip install PyPDF2命令进行安装。在上述示例中，您需要将pdf_path变量替换为您要处理的实际PDF文件的路径，并将target_text变量替换为您要搜索的目标文本。脚本将输出包含目标文本的文本框的总数。
