问题 I am trying to parse iTunes Playlist by using iterparse() of ElementTree but getting following error: AttributeError: 'Element' object has no attribute 'xpath' Code is given below: import xml.etree.ElementTree as ET context = ET.iterparse(file,events=("start", "end")) # turn it into an iterator context = iter(context) # get the root element event, root = context.next() for event, elem in context: z = elem.xpath(".//key") elem.clear() root.clear() print z What I am doing wrong? File is too big

问题 This question already has answers here : Using Python Iterparse For Large XML Files (6 answers) Parsing large XML using iterparse() consumes too much memory. Any alternative? (2 answers) using lxml and iterparse() to parse a big (+- 1Gb) XML file (3 answers) Closed 9 months ago . I am not able to parse XML file of huge size using lxml tree. What I came to know from my research is that lxml iterparse loads the xml file until it gets tag which it is looking for. This is snippet of my code :-

how to find and edit tags in XML files with namespaces using ElementTree

问题 I would like to find specific tags in my XML document and edit their text or attributes. My XML file contains namespaces (and as I understand it correctly, nested namespaces). The tool I'd like to use for this purpose is ElementTree. I managed to read XML file by iterparse , however I don't know how I can save edited XML, because iterparse doesn't have write element. I need a solution to read XML file by parse and strip its namespaces and nested namespaces or a way to save iterparsed file.

问题 I use Python's iterparse to parse the XML result of a nessus scan (.nessus file). The parsing fails on unexpected records, wile similar ones have been parsed correctly. The general structure of the XML file is a lot of records like the one below: <ReportHost> <ReportItem> <foo>9.3</foo> <bar>hello</bar> </ReportItem> <ReportItem> <foo>10.0</foo> <bar>world</bar> </ReportHost> <ReportHost> ... </ReportHost> In other words a lot of hosts ( ReportHost ) with a lot of items to report ( ReportItem

Ignore encoding errors in Python (iterparse)?

问题 I've been fighting with this for an hour now. I'm parsing an XML-string with iterparse . However, the data is not encoded properly, and I am not the provider of it, so I can't fix the encoding. Here's the error I get: lxml.etree.XMLSyntaxError: line 8167: Input is not proper UTF-8, indicate encoding ! Bytes: 0xEA 0x76 0x65 0x73 How can I simply ignore this error and still continue on parsing? I don't mind, if one character is not saved properly, I just need the data. Here's what I've tried,

问题 I have an XML file with nodes that looks like this: <trkpt lat="-37.7944415" lon="144.9616159"> <ele>41.3681107</ele> <time>2015-04-11T03:52:33.000Z</time> <speed>3.9598</speed> </trkpt> I am using lxml.etree.iterparse() to iteratively parse the tree. I loop over each trkpt element's children and want to print the text value of the children nodes. E.g. for event, element in etree.iterparse(infile, events=("start", "end")): if element.tag == NAMESPACE + 'trkpt': for child in list(element):

问题 I have a network application (using Twisted) that receives chunks of xml (as in the entire xml may not come in its entirety in a single packet) over the internet. My thought process is to slowly build the xml message as it's received. I've "settled" on iterparse from xml.etree.ElementTree. I've been dabbling in some code and the following (non-Twisted code) works fine: import xml.etree.ElementTree as etree from io import StringIO buff = StringIO(unicode('<notorious><burger/></notorious>'))
