问题内容
我当前正在使用 lxml 并希望验证 xml 内容。
我从 tei = etree.element("tei", nsmap={none: 'http://www.tei-c.org/ns/1.0'} 完全用 python 编写，包含许多子元素。 p>
现在，我想使用以下代码使用特定的 .xsd 文件检查结构是否正确：
xmlschema_doc = etree.parse(xsd_file_path)
xmlschema = etree.xmlschema(xmlschema_doc)
# run check
status = xmlschema.validate(xml_tree)
登录后复制
它返回 false，并显示错误 element 'tei'：没有可用于验证 root. 的匹配全局声明
我观察到一件非常奇怪的事情，如果我使用 编写 xml
et = etree.elementtree(xmldata)
et.write('test.xml', pretty_print=true, xml_declaration=true, encoding='utf-8')登录后复制
如果我用 b= etree.parse('test.xml') 重新打开它，我最终没有错误，并且由于 xmlschema.validate(b) 的结果，xml 结构是有效的
知道我需要在 xml 结构中添加什么吗？

正确答案
看看https://www.php.cn/link/e1ff36b97044a1c7c73c73e4d27aeba4，你基本上应该使用
tei_namespace = "http://www.tei-c.org/ns/1.0"
tei = "{%s}" % tei_namespace
nsmap = {none : tei_namespace} # the default namespace (no prefix)
root = etree.element(tei + "tei", nsmap=nsmap) # lxml only!
text = etree.subelement(root, tei + "text")登录后复制
对所有元素依此类推，以确保它们是在 tei 命名空间中创建的。
在内存中创建的 elementtree 对架构有效（在我将其与导入的 w3c xml.xsd 一起下载后）是例如
from lxml import etree
TEI_NAMESPACE = "http://www.tei-c.org/ns/1.0"
TEI = "{%s}" % TEI_NAMESPACE
NSMAP = {None : TEI_NAMESPACE} # the default namespace (no prefix)
root = etree.Element(TEI + "TEI", nsmap=NSMAP) # lxml only!
text = etree.SubElement(root, TEI + "text")
body = etree.SubElement(text, TEI + "body")
listBibl = etree.SubElement(body, TEI + "listBibl")
biblFull = etree.SubElement(listBibl, TEI + "biblFull")
sourceDesc = etree.SubElement(biblFull, TEI + "sourceDesc")
profileDesc = etree.SubElement(biblFull, TEI + "profileDesc")
xmlschema_doc = etree.parse("aofr.xsd")
xmlschema = etree.XMLSchema(xmlschema_doc)
# run check
status = xmlschema.validate(root)
print(status)
print(xmlschema.error_log)登录后复制
以上是无法使用架构验证 XML，但可以通过从中读取写入的文件来工作的详细内容。更多信息请关注PHP中文网其他相关文章！
