Beautiful Soup - `findAll` not capturing all tags in SVG (`ElementTree` does)

问题 I was attempting to generate a choropleth map by modifying an SVG map depicting all counties in the US. The basic approach is captured by Flowing Data. Since SVG is basically just XML, the approach leverages the BeautifulSoup parser. The thing is, the parser does not capture all path elements in the SVG file. The following captured only 149 paths (out of over 3000): #Open SVG file svg=open(shp_dir+'USA_Counties_with_FIPS_and_names.svg','r').read() #Parse SVG soup = BeautifulSoup(svg,

问题 When generating a XML file using ElementTree, you can add a comment on the line below an element by using insert , e.g. import xml.etree.ElementTree as ET tree = ET.ElementTree("test.xml") # modifying existing XML file tree.getroot().insert(0, ET.Comment("Some comment...")) tree.write("test_modified.xml") This results in an output looking something like this: <RootElement> <NextElement> </NextElement> </RootElement> Is there a way to add a comment on the first line

I'm trying to append a child node onto ele that contains a namespace prefix (called style) in its tag. ele seems to be aware of this prefix, as the line: print(ele.nsmap['style']) outputs urn:oasis:names:tc:opendocument:xmlns:style:1.0 But when I try to run ele.append(etree.fromstring('<style:style />')) I get the error lxml.etree.XMLSyntaxError: Namespace prefix style on style is not defined What am I missing here? 回答1: etree.fromstring('<style:style />') throws an

Running out of memory using python ElementTree

阅读更多关于 Running out of memory using python ElementTree

问题 EDIT: Anyone coming to this in the future, the solution I used was to switch to cElementTree. It not only runs with less memory, it is significantly faster. This works on files up to about 600mb in size, larger than that and I run out of memory (I have a 16gb machine). What can I do to read in a file in pieces, or read in a certain percentage of the xml at a time or is there a less memory intensive approach? import csv import xml.etree.ElementTree as ET from lxml import etree import time

When I try want to change value in NameY the script changes for all the values(even for NameX). I believe
