elementtree

问题 I want parse multi xml file into dataframe. There are same xpath. I have used element tree and os Python library.It can parse all the files, but it print out empty dataframe. However if code without multiple file, it can work properly. mypath = r'C:\Users\testFile' files = [path.join(mypath, f) for f in listdir(mypath) if f.endswith('.xml')] for file in files: xtree = et.parse(file) xroot = xtree.getroot() df_cols=['value'] out_xml=pd.DataFrame(columns=df_cols) for node in xroot.findall(r'.

问题 I have a TEI-encoded xml file with entities as follows: <sp> <speaker rend="italic">Sampson.</speaker> <ab> <lb n="5"/> <hi rend="italic">Gregory:</hi> <seg type="homograph">A</seg> my word wee'l not carry coales.<lb n="6"/> </ab> </sp> <sp> <speaker rend="italic">Greg.</speaker> <ab>No, for then we should be Colliars. <lb n="7" rend="rj"/> </ab> </sp> The full file is very large but can be accessed here: http://ota.ox.ac.uk/desc/5721. I'm attempting to use Python 3 to traverse the xml and

问题 I'm having a few problems with parsing simple HTML with use of the ElementTree module out of the standard Python libraries. This is my source code: from urllib.request import urlopen from xml.etree.ElementTree import ElementTree import sys def main(): site = urlopen("http://1gabba.in/genre/hardstyle") try: html = site.read().decode('utf-8') xml = ElementTree(html) print(xml) print(xml.findall("a")) except: print(sys.exc_info()) if __name__ == '__main__': main() Either this fails, I get the

问题 The code below takes an XML file and parses specific elements into a CSV file. Regarding the code I had simpler and different code that had a slightly different out, the code below is as an outcome of a lot help from here. from xml.etree import ElementTree as ET from collections import defaultdict import csv tree = ET.parse('thexmlfile.xml') root = tree.getroot() with open('output.csv', 'w', newline='') as f: writer = csv.writer(f) start_nodes = root.findall('.//START') headers = ['id',

问题 I have a set of XML files that I need to read and format into a single CSV file. In order to read from the XML files, I have used the solution mentioned here. My code looks like this: from os import listdir import xml.etree.cElementTree as et files = listdir(".../blogs/") for i in range(len(files)): # fname = ".../blogs/" + files[i] f = open(".../blogs/" + files[i], 'r') contents = f.read() tree=et.fromstring(contents) for el in tree.findall('post'): post = el.text f.close() This gives me the

问题 I am using Python xml.etree.ElementTree to output XML. I want to output it with entity references that will be substituted when the XML is parsed. ordinarily '&' is escaped as & because '&' is used to declare entity references. However, I really do want to write an entity reference. For example, I want to write an XML file containing the entity reference &manifestName; : >>> from xml.etree.ElementTree import Element, tostring >>> manifest = Element('manifest') >>> manifest.text = '

问题 I must be missing something. I'm attempting to set up a google product feed, but am having a hard time registering the namespace.
