如何解析嵌套的 XML？

Question

I have an XML file from which I want to extract certain values:

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="MeasDataCollection.xsl"?>

With xml.etree.ElementTree I am not having luck. Can someone please provide direction?

Answer 1

So you can do something like below to find your tags and text

   from lxml import etree
   tree = etree.parse('C:\\Users\\sb_meyer.xml')
   #print(tree)
   root = tree.getroot()
   #print(root)
   for neid_values in tree.findall('.//neid//'):
       print(neid_values.tag,neid_values.text)
