我是Python和XPATH的初学者，需要使用XPATH读取具有非统一节点（类似于下面提到的节点）的XML。下面还显示了要写入文件的输出格式。该代码使用lxml库。
请帮助我建立正确的XPATH。

此代码将帮助：
from lxml import html
xml_content = """<Classes>
<German>
<Student>
<Span><a href="">John</a></Span>
</Student>
<Student>
<Span>Adam</Span>
</Student>
</German>
<English>

</Classes>"""
tree = html.fromstring(xml_content)
classes = tree.xpath('//classes/*')
for language_class in classes:
print language_class.tag.capitalize()
for student in language_class.xpath('.//student/span//text()'):
print " {}".format(student)
输出：
