I am currently using lxml
and want to validate the xml content.
I started from tei = etree.element("tei", nsmap={none: 'http://www.tei-c.org/ns/1.0'}
Completely written in python, including Many child elements. p>
Now, I want to check if the structure is correct using a specific .xsd
file using the following code:
xmlschema_doc = etree.parse(xsd_file_path) xmlschema = etree.xmlschema(xmlschema_doc) # run check status = xmlschema.validate(xml_tree)
It returns false with error element 'tei': No matching global declaration available to verify root.
I observed a very strange thing, if I write xml using
et = etree.elementtree(xmldata) et.write('test.xml', pretty_print=true, xml_declaration=true, encoding='utf-8')If I reopen it with
b= etree.parse('test.xml') I end up with no errors, and as a result of
xmlschema.validate(b), The xml structure is valid
edit: Invalid first item in xml
The first item in a valid xml file
edit:

https://www.php.cn/link/e1ff36b97044a1c7c73c73e4d27aeba4, you should basically use
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")And so on for all elements to ensure they are created in the tei namespace.
The elementtree created in memory valid for the schema (after I downloaded it with the imported w3c xml.xsd) is e.g.
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)
