从PSQL数据库表生成XML文件的Python脚本可以通过以下步骤实现:
import psycopg2
import xml.etree.ElementTree as ET
conn = psycopg2.connect(database="your_database", user="your_username", password="your_password", host="your_host", port="your_port")
cur = conn.cursor()
cur.execute("SELECT * FROM your_table")
rows = cur.fetchall()
root = ET.Element("data")
for row in rows:
item = ET.SubElement(root, "item")
# 添加子元素并设置属性
ET.SubElement(item, "column1").text = str(row[0])
ET.SubElement(item, "column2").text = str(row[1])
# 添加更多列...
tree = ET.ElementTree(root)
tree.write("output.xml")
完整的Python脚本示例:
import psycopg2
import xml.etree.ElementTree as ET
conn = psycopg2.connect(database="your_database", user="your_username", password="your_password", host="your_host", port="your_port")
cur = conn.cursor()
cur.execute("SELECT * FROM your_table")
rows = cur.fetchall()
root = ET.Element("data")
for row in rows:
item = ET.SubElement(root, "item")
ET.SubElement(item, "column1").text = str(row[0])
ET.SubElement(item, "column2").text = str(row[1])
tree = ET.ElementTree(root)
tree.write("output.xml")
这个Python脚本可以用于从PSQL数据库表生成XML文件。它连接到指定的PSQL数据库,执行查询语句获取数据,并将数据转换为XML格式保存为output.xml文件。你可以根据实际情况修改数据库连接参数、查询语句和输出文件名。
