Saya sedang menggunakan lxml
dan ingin mengesahkan kandungan xml.
Saya bermula dengan tei = etree.element("tei", nsmap={none: 'http://www.tei-c.org/ns/1.0'}
ditulis sepenuhnya dalam python dan mengandungi banyak sub-elemen. p>
Sekarang saya ingin menyemak sama ada struktur itu betul menggunakan fail .xsd
tertentu menggunakan kod berikut:
xmlschema_doc = etree.parse(xsd_file_path) xmlschema = etree.xmlschema(xmlschema_doc) # run check status = xmlschema.validate(xml_tree)
Ia mengembalikan palsu dan memaparkan ralat element 'tei':没有可用于验证 root.
untuk pengisytiharan global yang sepadan
Saya perhatikan satu perkara yang sangat pelik, jika saya menulis xml menggunakan
et = etree.elementtree(xmldata) et.write('test.xml', pretty_print=true, xml_declaration=true, encoding='utf-8')Jika saya menggunakan hasil
, struktur xml adalah sahb= etree.parse('test.xml')
重新打开它,我最终没有错误,并且由于 xmlschema.validate(b)
Editor: Item pertama tidak sah dalam xml
Item pertama dalam fail xml yang sah

https://www.php.cn/link/e1ff36b97044a1c7c73c73e4d27aeba4, anda pada dasarnya harus menggunakan
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")Dan seterusnya untuk semua elemen untuk memastikan ia dicipta dalam ruang nama tei.
Elementtree yang dicipta dalam memori sah untuk skema (selepas saya memuat turunnya dengan w3c xml.xsd yang diimport) ialah cth
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)
Atas ialah kandungan terperinci Tidak dapat mengesahkan XML menggunakan skema, tetapi berfungsi dengan membaca fail yang ditulis daripada. Untuk maklumat lanjut, sila ikut artikel berkaitan lain di laman web China PHP!
