如何在假脱机XML结果时查询特定行数以避免缓冲区溢出

import xml.etree.ElementTree as ET

def query_specific_rows(xml_data, num_rows):
    root = ET.fromstring(xml_data)
    rows = []
    count = 0

    for row in root.iter('row'):
        if count >= num_rows:
            break

        # 提取行数据并存储在列表中
        row_data = {}
        for child in row:
            row_data[child.tag] = child.text
        rows.append(row_data)

        count += 1

    return rows

# 示例用法
xml_data = """
<results>
    <row>
        <id>1</id>
        <name>John</name>
    </row>
    <row>
        <id>2</id>
        <name>Jane</name>
    </row>
    <row>
        <id>3</id>
        <name>Bob</name>
    </row>
</results>
"""

num_rows = 2
result = query_specific_rows(xml_data, num_rows)
print(result)
