从SAP2000 XML截面库提取数据到Excel

问题

SAP2000的截面库是XML格式，带有命名空间，直接用Python解析会找不到元素。

解决方案

python 复制代码

import xml.etree.ElementTree as ET
import pandas as pd

# XML文件路径
path = r'E:\Program Files\Computers and Structures\SAP2000 26\Property Libraries\Sections\BSShapes2006.xml'

tree = ET.parse(path)
root = tree.getroot()

# 关键：定义命名空间
ns = {'csi': 'http://www.csiberkeley.com'}

# 提取数据（以STEEL_ANGLE为例，可改成其他截面类型）
data = []
for section in root.findall('.//csi:STEEL_ANGLE', ns):
    row = {}
    for child in section:
        tag = child.tag.replace('{http://www.csiberkeley.com}', '')
        row[tag] = child.text
    data.append(row)

# 导出Excel
df = pd.DataFrame(data)
df.to_excel('sections.xlsx', index=False)

常见截面类型标签

标签	截面类型
`STEEL_ANGLE`	角钢
`STEEL_I_SECTION`	工字钢
`STEEL_CHANNEL`	槽钢
`STEEL_TEE`	T型钢
`STEEL_TUBE`	方管
`STEEL_PIPE`	圆管

批量提取所有类型

python 复制代码

import xml.etree.ElementTree as ET
import pandas as pd

path = r'你的XML路径.xml'
tree = ET.parse(path)
root = tree.getroot()

ns = {'csi': 'http://www.csiberkeley.com'}
section_types = ['STEEL_ANGLE', 'STEEL_I_SECTION', 'STEEL_CHANNEL', 
                 'STEEL_TEE', 'STEEL_TUBE', 'STEEL_PIPE']

with pd.ExcelWriter('all_sections.xlsx') as writer:
    for sec_type in section_types:
        data = []
        for section in root.findall(f'.//csi:{sec_type}', ns):
            row = {child.tag.split('}')[1]: child.text for child in section}
            data.append(row)
        if data:
            pd.DataFrame(data).to_excel(writer, sheet_name=sec_type, index=False)
