用Java将.csv文件解析为xml

大家好，我正在尝试制作一个程序，将.csv文件中的数据转换为.csv文件，构建.csv文件的DOM表示，然后将其输出到xml文件

我现在正在使用下面的代码解析.csv文件，但我不确定如何获取这些信息并构建DOM表示。我读了很多书，偶然发现了“jaxb”，但似乎

也许一个简单的、低代码的选择就是使用Jackson来实现这一点。有一种方法可以读取CSV文件（使用定义的模式-在本例中，您可以使用标题行），然后将其发送回XML（另一种自由行为）

可以使用以下方式读取CSV：

CsvSchema bootstrap = CsvSchema.emptySchema().withHeader();
CsvMapper csvMapper = new CsvMapper();
MappingIterator<Map<?, ?>> mappingIterator = csvMapper.reader(Map.class).with(bootstrap).readValues(file);

当然，还有很多其他的选择。至少要使用CSV解析器，例如，不要试图手动解析CSV（存在太多潜在问题，其中大多数问题已经得到有力解决）。

可能重复：

XmlMapper xmlMapper = new XmlMapper();
xmlMapper.writeValue(mappingIterator.next....
