如何使用python捕获XML文件中另一个标签下的标签

问题描述 投票：0回答：0
        myroot = xmltree.getroot()

        for i in myroot.iter('record'):
            for j in i.iter(): 
                if(j.tag not in ignoretags):
                    if file_header_print:
                        headstr = "{}:{}".format(headstr,j.tag)
                    datastr = "{}:{}".format(datastr,j.text)

            if file_header_print:
                file_header_print = False
                logger.info(headstr)
            logger.info(datastr)

logger.info("Audit Report capture process end")

我的主代码中的上述代码捕获了xml文件中的标头标记，并将其打印在我的日志报告中。我在下面给出了示例日志报告。

上面代码的第一行是有值的标签，下面是每个xml文件的值。我在下面给出了我的示例 xml 文件，我们可以在其中看到具有值的标签。 

organization
、
case_id
、
invoice_number
等是我在上面给出的日志文件顶部的那个。

现在我的问题是 

record
标签内的标签只在我的日志中捕获。可以看到xml文件中有一个
row
标签。那些
row_number
，
order_number
，
product_code
等未在日志文件的标题中捕获。但价值被捕获。我想修改问题顶部的上述代码，以捕获
row
标签内的标签以及日志文件中的标题。

捕获

row
标签中的值没有问题。唯一的问题是 
row
标签的标题没有被打印出来。我该如何解决？

NP：日志中的header表示：
