这是我的代码:
#!/usr/bin/python
import psycopg2
import sys
from lxml import etree
def main():
#Define our connection string
conn_string = ("host=host dbname=lal user=user password=pass")
# get a connection, if a connect cannot be made an exception will be raised here
conn = psycopg2.connect(conn_string)
# conn.cursor will return a cursor object
cursor = conn.cursor()
print "Connected!\n"
# Open file
parser = etree.parse("XML/epg.xml")
for row in parser:
print row
postgres = ('INSERT INTO epg_live (channel_id, program, start, duration) VALUES (%s, %s, %s, %s)', (row, row, row, row))
cursor.execute(parser,postgres)
cursor.commit()
print "Gotovo!"
if __name__ == "__main__":
main()
您能帮我将 XML 文件解析为字符串并插入到 posgresql 中的表中吗?当我运行脚本时,我收到如下错误:
File "./xml.py", line 32, in <module>
main()
File "./xml.py", line 22, in main
parser = etree.parse("XML/epg.xml")

lxml.etree.XMLSyntaxError: Opening and ending tag mismatch: epg line 2 and item, line 26, column 10
我的 XML 很好,看起来像:
<item><program> Program 3
</program><start> Start 20130918 15:00:00
</start><duration> Duration 04:30:00
</duration><title> Title Nujna seja Odbora za finance in monetarno politiko
</title></item>
你能帮我解决一些python的问题吗,谢谢大家阅读这篇文章。
