我使用ElementTree的與Python解析XML文件來尋找subchildElementTree的find()方法總是返回無
的內容,這是我試圖解析XML文件:
<?xml version='1.0' encoding='UTF-8'?>
<nvd xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://nvd.nist.gov/feeds/cve/1.2" nvd_xml_version="1.2" pub_date="2016-02-10" xsi:schemaLocation="http://nvd.nist.gov/feeds/cve/1.2 http://nvd.nist.gov/schema/nvdcve_1.2.1.xsd">
<entry type="CVE" name="CVE-1999-0001" seq="1999-0001" published="1999-12-30" modified="2010-12-16" severity="Medium" CVSS_version="2.0" CVSS_score="5.0" CVSS_base_score="5.0" CVSS_impact_subscore="2.9" CVSS_exploit_subscore="10.0" CVSS_vector="(AV:N/AC:L/Au:N/C:N/I:N/A:P)">

這是我的代碼:
import xml.etree.ElementTree as ET
if __name__ == '__main__':
tree = ET.parse('nvdcve-modified.xml')
root = tree.getroot()
print root.find('entry')
print root[0].find('desc')
輸出爲無兩行
感謝這個作品! –
