With the continued growth of both Python and XML, there is a plethora(过剩/过多) of packages out there that help you read, generate, and modify XML files from Python scripts. Compared to most of them, the lxml package has two big advantages: Performance. Reading and writing even fairly l...
dom=xml.dom.minidom.parse('roi.xml') #得到xml文档元素对象 root=dom.documentElement #开始操作 #获取readSession标签集并且继续获取标签集中第一个readSession下的xCoord标签集 roiX=root.getElementsByTagName('readingSession')[0].getElementsByTagName('roi')[0].getElementsByTagName('xCoord') #获取到了...
XML格式适合阅读,并且是可编辑的,可以使用单独的工具进行处理。XML文件格式的分析是直接的,XML分析器速度可能会较慢,因此,读入很大的XML文件回避读入同样大小的二进制文件或文本文件耗费更多的时间资源。 1、文件操作函数 1.1 open() 提到文件操作,那就必须提到 open 函数,因为无论是读取还是写入,都需要先把文件打开...
