• 支持通过固定布局获取页的内容。

// 指定文件路径
wstring input_path = datapath;
wstring inputfile = input_path   l"in.docx";
wstring output_path = outputpath;
wstring outputfile = output_path   l"out.txt";
// 创建一个新的 document 实例
intrusive_ptr document = new document();
// 从指定文件加载文档
document->loadfromfile(inputfile.c_str(), fileformat::docx);
intrusive_ptr layoutdoc = new fixedlayoutdocument(document);
wstring result;
// 使用加载的文档创建一个fixedlayoutdocument对象
intrusive_ptr line = layoutdoc->getpages()->getitem(0)->getcolumns()->getitem(0)->getlines()->getitem(0);
result.append(l"line: ");
result.append(line->gettext());
result.append(l"\n");
// 检索与该行关联的原始段落
intrusive_ptr para = line->getparagraph();
result.append(l"paragraph text: ");
result.append(para->gettext());
result.append(l"\n");
// 以纯文本格式检索第一页上出现的所有文本（包括页眉和页脚）
wstring pagetext = layoutdoc->getpages()->getitem(0)->gettext();
result.append(pagetext);
result.append(l"\n");
// 循环遍历文档中的每一页并打印每页上出现的行数
for (int i = 0; i < layoutdoc->getpages()->getcount(); i  )
{
	intrusive_ptr page = layoutdoc->getpages()->getitem(i);
	intrusive_ptr lines = page->getchildentities(layoutelementtype::line, true);
	result.append(l"page ");
	result.append(std::to_wstring(page->getpageindex()));
	result.append(l" has ");
	result.append(std::to_wstring(lines->getcount()));
	result.append(l" lines.");
	result.append(l"\n");
}
// 对第一段的布局实体执行反向查找
result.append(l"\n");
result.append(l"the lines of the first paragraph:");
result.append(l"\n");
intrusive_ptr para2 = (object::dynamic_cast
(document->getfirstchild()))->getbody()->getparagraphs()->getiteminparagraphcollection(0);
intrusive_ptr paragraphlines = layoutdoc->getlayoutentitiesofnode(para2);
for (int i = 0; i < paragraphlines->getcount(); i  )
{
	intrusive_ptr paragraphline = object::dynamic_cast(paragraphlines->getitem(i));
	result.append(paragraphline->gettext());
	result.append(l"\n");
	result.append(paragraphline->getrectangle()->tostring());
	result.append(l"\n");
	result.append(l"\n");
}
// 将提取的文本写入文件
std::wofstream write(outputfile);
auto locutf8 = locale(locale(""), new std::codecvt_utf8);
write.imbue(locutf8);
write << result;
write.close();
// 处理文档资源
document->dispose();
