Chúng tôi đã thấy cách phân tích tệp XML bằng Python ở đây. Trong bài đăng này, chúng tôi sẽ thảo luận về việc thay đổi giá trị phần tử của tệp XML bằng Python. Chúng tôi sẽ sử dụng mô -đun xml.etree.elementtree để thay đổi tệp XML.xml.etree.ElementTree in order to make changes to the xml file. Hãy để chúng tôi tạo một tệp XML bằng cách sử dụng nội dung dưới đây và đặt tên cho nó là ví dụ.xml. Mục tiêu của chúng tôi là thay đổi giá của cuốn sách hướng dẫn của Python Python từ 30,00 lên 50,00. Đầu tiên chúng tôi sẽ lặp qua tất cả các cuốn sách và tìm cuốn sách có tiêu đề phù hợp và sau đó áp dụng các thay đổi của chúng tôi. Một điều quan trọng cần lưu ý là mã trên sẽ ghi đè lên tệp XML gốc với giá trị được cập nhật.

import xml.etree.ElementTree as ET
filename = "example.xml"
xmlTree = ET.parse[filename]
rootElement = xmlTree.getroot[]
for element in rootElement.findall["book"]:
#Find the book that has title as 'Python Tutorial'
if element.find['title'].text == 'Python Tutorial' :
#Change the price
element.find['price'].text = "50.00"
#Write the modified xml file.
xmlTree.write[filename,encoding='UTF-8',xml_declaration=True]
Tôi đang cố gắng sử dụng thư viện ElementTree
của Python 2.7 để phân tích tệp XML, sau đó thay thế các thuộc tính phần tử cụ thể bằng dữ liệu thử nghiệm, sau đó lưu đây là tệp XML duy nhất.
Ý tưởng của tôi về một giải pháp là [1] nguồn dữ liệu mới từ tệp CSV bằng cách đọc tệp thành chuỗi, [2] cắt chuỗi ở một số dấu phân cách nhất định, [3] nối vào danh sách, và sau đó [4] sử dụng ElementTree
để cập nhật/xóa/thay thế thuộc tính bằng một giá trị cụ thể từ danh sách.
Tôi đã xem trong tài liệu ElementTree
và thấy các chức năng clear[]
và remove[]
, nhưng tôi không biết về cú pháp để sử dụng chúng một cách đầy đủ.
Một ví dụ về XML để sửa đổi là bên dưới - các thuộc tính có XXXXX
sẽ được thay thế/cập nhật:
Kết quả dự định sẽ là, ví dụ:
Làm cách nào để sử dụng các lệnh
import xml.etree.ElementTree as ET
filename = "example.xml"
xmlTree = ET.parse[filename]
rootElement = xmlTree.getroot[]
for element in rootElement.findall["book"]:
#Find the book that has title as 'Python Tutorial'
if element.find['title'].text == 'Python Tutorial' :
#Change the price
element.find['price'].text = "50.00"
#Write the modified xml file.
xmlTree.write[filename,encoding='UTF-8',xml_declaration=True]

Extensible Markup Language [XML] is a markup language that defines a set of rules for encoding documents in
a format that is both human-readable and machine-readable.The design goals of XML focus on simplicity, generality, and usability across the Internet.It is a textual data format with strong support via Unicode for different human languages. Although the design of XML focuses on documents, the language is widely used for the representation of arbitrary data structures such as those used in web services.
XML is an inherently hierarchical data format, and the most natural way to represent it is
with a tree.To perform any operations like parsing, searching, modifying an XML file we use a modulexml.etree.ElementTree.It has two classes.ElementTree represents the whole XML document as a tree which helps while performing the operations. Element represents a
single node in this tree.Reading and writing from the whole document are done on the ElementTree level.Interactions with a single XML element and its sub-elements are done on the Element level.

We can parse XML data from a string or an XML document.Considering xml.etree.ElementTree as ET.
1. ET.parse[‘Filename’].getroot[] -ET.parse[‘fname’]-creates a tree and then we extract the root by .getroot[].
2. ET.fromstring[stringname] -To create a root from an XML data string.
Example 1:
XML document:
Số lượng phần tử trẻ em đến một gốc cụ thể.
Phân tích cú pháp: Chúng ta có thể phân tích dữ liệu XML từ một chuỗi hoặc tài liệu XML.Considing XML.ETREE.ElementTree là et.1. Et.parse [‘fileName,]. Et.FromString [StringName] -để tạo một gốc từ chuỗi dữ liệu XML.example 1: & nbsp; tài liệu XML: & nbsp;

Modifying the XML document can also be done through Element methods.
Methods:
1]Element.set[‘attrname’, ‘value’] – Modifying element attributes.
2]Element.SubElement[parent, new_childtag] -creates a new child tag under the parent.
3]Element.write[‘filename.xml’]-creates the tree of xml into another file.
4]Element.pop[] -delete a
particular attribute.
5]Element.remove[] -to delete a complete tag.
