我有一个非常简单的KML文件,在使用ElementTree解析时不返回任何节点。这令我很沮丧:-)。有线索吗?
from xml.etree import ElementTree
from pprint import pprint
kml = '''<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.0">
<Document>
<name>NEXRAD Radar Sites</name>
<Schema parent="Placemark" name="wsr">
<SimpleField type="wstring" name="STATE">
</SimpleField>
</Schema>
<wsr>
<name>KABR</name>
</wsr>
</Document>
</kml>
'''
tree = ElementTree.fromstring(kml)
ElementTree.dump(tree)
for node in tree.iter('wsr'):
pprint(node)
for node in tree.findall('../wsr'):
pprint(node)
答案 0 :(得分:4)
标签是命名空间。如果您尝试tree.iter()
没有标记,它将显示ElementTree认为标记被调用的内容。 wsr
标记名为{http://earth.google.com/kml/2.0}wsr
。这将返回一个节点:
list(tree.iter('{http://earth.google.com/kml/2.0}wsr'))
