Excel XML到Java对象

Question

我在使用Excel打开xml文件时遇到了一点问题。客户机向我发送了以下类型的XML：

<?xml version="1.0"?>
<?mso-application progid="Excel.Sheet"?>

        List<MULSite> siteList = new ArrayList<MULSite>();

        } catch (IOException | RetrieverException | JAXBException e) {
            e.printStackTrace();
        }
    }

但是，当它到达:workbook workbook=workbookfactory.create(inp)；时，它会抛出以下错误:java.lang.IllegalArgumentException:您的InputStream既不是OLE2流，也不是OOXML流

我对如何处理这种类型的文件有点困惑，我尝试将扩展名从。xml更改为。xls，Excel可以用两种方式完美地打开它，但Apache POI不接受它，我不确定是文件的问题还是我如何用InputStream读取它。

Answer 1

遗憾的是，这是不可能的，Apache POI不支持Office XML，它从来没有在库中实现过，因为微软很快就不赞成这样做。

我已经放弃了使用Apache POI来完成这一任务的尝试，并将使用XML解析器将其解析为DOM。
