如何将xml绑定到datagrid组合框

import xml.etree.ElementTree as ET

# 解析XML文件
tree = ET.parse('data.xml')
root = tree.getroot()

# 将XML数据转换为字典列表
data = []
for item in root.findall('item'):
    row = {}
    row['name'] = item.find('name').text
    row['age'] = item.find('age').text
    data.append(row)

<DataGrid x:Name="datagrid" AutoGenerateColumns="False">
    <DataGrid.Columns>
        <DataGridTextColumn Header="Name" Binding="{Binding Name}" />
        <DataGridTextColumn Header="Age" Binding="{Binding Age}" />
    </DataGrid.Columns>
</DataGrid>

// 设置数据源
datagrid.ItemsSource = data;

// 或者逐列绑定
DataGridTextColumn nameColumn = new DataGridTextColumn();
nameColumn.Header = "Name";
nameColumn.Binding = new Binding("Name");
datagrid.Columns.Add(nameColumn);

DataGridTextColumn ageColumn = new DataGridTextColumn();
ageColumn.Header = "Age";
ageColumn.Binding = new Binding("Age");
datagrid.Columns.Add(ageColumn);

# 更新XML数据
for i, row in enumerate(data):
    item = root.findall('item')[i]
    item.find('name').text = row['name']
    item.find('age').text = row['age']

# 保存更新后的XML文件
tree.write('data.xml')
