问题 I'm building a Python file that communicates with a PLC. When compiling, the PLC creates a XML file that delivers important information about the program. The XML looks more less like this: <visu> <time>12:34</time> <name>my_visu</name> <language>english</language> <vars> <var name="input1">2</var> <var name="input2">45.6</var> <var name="input3">"hello"</var> </vars> </visu> The important part is found under child "vars". Using Python I want to make a file that when sending argument "input2"

问题 Wrote a code to parse .osm file. Spend a lot of time to build a up to 50 rows code but ran into a 'Memory Error' problem. Seems like the best solution is to use interparse() instead of parse(). My question is: how should I change my code (strating of my code) import xml.etree.ElementTree as ET tree = ET.parse('file.osm') root = tree.getroot() to ( using interparse() method) (not my code) import xml.etree.ElementTree as etree context=etree.iterparse('file.osm', events=('start', 'end', 'start

问题 I'm using Python's ElementTree to parse xml files. I have a "findall" to find all "revision" subelements, but when I iterate through the result, they are not in document order. What can I be doing wrong? Here's my code: allrevisions = page.findall('{http://www.mediawiki.org/xml/export-0.5/}revision') for rev in allrevisions: print rev print rev.find('{http://www.mediawiki.org/xml/export-0.5/}timestamp').text Here's a link to the document I'm parsing: http://pastie.org/2780983 Thanks, bsg

问题 I want to extract all text in xml document, and I am having a problem for the following case: ... <a> hello <B> there </B> How was your day. ..... </a> In this snippet, I can get the text "hello" and "there" because I can get them using the following tags: a.text b.text but I don't know how to access the "How was your day." part. 回答1: You are looking for the .tail attribute of an element: >>> from xml.etree import ElementTree >>> example = ElementTree.fromstring('''\ ... <a> ... hello ... <B>

问题 here's my code: from elementTree.elementtree.ElementTree import Element, parse, ElementTree f = open("myxml.xml", 'r') tree = parse(f) root = tree.getroot() f2 = open('out.xml', 'w') print tree print root props = root.findall('property') print props tree.write(f2) Stacktrace: Traceback (most recent call last): File "xmlpy.py", line 11, in <module> props = root.findall('property') File "D:\user-testing-areas\DWJ\py\elementTree\elementtree\ElementTree.py", li ne 390, in findall return

问题 I want to use xml.etree.ElementTree to parse an XHTML document in Python 3. The document contains   entities, so I cannot use the default parser settings. I'd like to do something similar to: with urllib.request.urlopen(BASE_URL) as url: body = url.read() parser = ET.XMLParser() parser.parser.UseForeignDTD(True) parser.entity.update(entitydefs) etree = ET.ElementTree() root = etree.fromstring(body) But fromstring is a free function in ElementTree . How can I achieve something similar with

问题 I am trying to write this text value to the XML tag like this <Parameter name="name"><![CDATA[xyzvalue]]></Parameter> Whenever, i am setting this value as text to this tag.
