I am having trouble using the attribute XPath Selector in ElementTree, which I should be able to do according to the Documentation Here's some sample code XML <root> <target name="1"> <a></a> <b></b> </target> <target name="2"> <a></a> <b></b> </target> </root> Python def parse(document): root = et.parse(doc...
In my Python app, I have an XML document that I'd like to transform using my XSL file. I'm currently using xml.etree to generate the XML document, but I haven't found anything within Python 2.5 that will allow me to natively transform my XML document. I've already found one library (libxslt) which can execute the transformation, but I ...
I have an object that can build itself from an XML string, and write itself out to an XML string. I'd like to write a unit test to test round tripping through XML, but I'm having trouble comparing the two XML versions. Whitespace and attribute order seem to be the issues. Any suggestions for how to do this? This is in Python, and I'm usi...
That is, all text and subtags, without the tag of an element itself? Having <p>blah <b>bleh</b> blih</p> I want blah <b>bleh</b> blih element.text returns "blah " and etree.tostring(element) returns: <p>blah <b>bleh</b> blih</p> ...
I'm parsing an xml file using Python's ElementTree, like that: et = ElementTree(file=file("test.xml")) test.xml starts with a few lines of xml comments. Is there a way to get those comments from et? ...
Hey guys, I need to parse an XML file and build a record-based output from the data. The problem is that the XML is in a "generic" form, in that it has several levels of nested "node" elements that represent some sort of data structure. I need to build the records dynamically based on the deepest level of the "node" element. Some exa...
I want to add doctypes to my XML documents that I'm generating with LXML's etree. However I cannot figure out how to add a doctype. Hardcoding and concating the string is not an option. I was expecting something along the lines of how PI's are added in etree: pi = etree.PI(...) doc.addprevious(pi) But it's not working for me. How ...
I'm trying to take a string of text, and "extract" the rest of the text in the paragraph/document from the html. My current is approach is trying to find the "parent tag" of the string in the html that has been parsed with lxml. (if you know of a better way to tackle this problem, I'm all ears!) For example, search the tree for "TEXT S...
I have been developing an application with django and elementtree and while deploying it to the production server i have found out it is running python 2.4. I have been able to bundle elementtree but now i am getting the error: "No module named expat; use SimpleXMLTreeBuilder instead" Unfortunately i cannot upgrade python so im stuck ...
I am trying to use Python's ElementTree to generate an XHTML file. However, the ElementTree.Element() just lets me create a single tag (e.g., HTML). I need to create some sort of a virtual root or whatever it is called so that I can put the various , DOCTYPES, etc. How do I do that? Thanks ...
Hi all! I am using ElementTree to parse a XML file. In some fields, there will be HTML data. For example, consider a declaration as follows: <Course> <Description>Line 1<br />Line 2</Description> </Course> Now, supposing _course is an Element variable which hold this Couse element. I want to access this course's description, so I ...
I am parsing some XML with the elementtree.parse() function. It works, except for some utf-8 characters(single byte character above 128). I see that the default parser is XMLTreeBuilder which is based on expat. Is there an alternative parser that I can use that may be less strict and allow utf-8 characters? This is the error I'm gett...
By default, when you call ElementTree.parse(someXMLfile) the Python ElementTree library prefixes every parsed node with it's namespace URI in Clark's Notation: {http://example.org/namespace/spec}mynode This makes accessing specific nodes by name a huge pain later in the code. I've read through the docs on ElementTree and namespa...
Most web applications have a Location field, in which uses may enter a Location of their choice. How would you classify users into different countries, based on the location entered. For eg, I used the Stackoverflow dump of users.xml and extracted users' names, reputation and location: ['Jeff Atwood', '12853', 'El Cerrito, CA'] ['Jarr...
I am having a heck of a time using ElementTree 1.3 in Python. Essentially, ElementTree does absolutely nothing. My XML file looks like the following: <?xml version="1.0"?> <ItemSearchResponse xmlns="http://webservices.amazon.com/AWSECommerceService/2008-08-19"> <Items> <Item> <ItemAttributes> <ListPrice> ...
In my Django project, the following line throws an ImportError: "No module named elementtree". from elementtree import ElementTree However, the module is installed (ie, I can run an interactive python shell, and type that exact line without any ImportError), and the directory containing the module is on the PYTHONPATH. But when I a...
I'm trying to create XML using the ElementTree object structure in python. It all works very well except when it comes to processing instructions. I can create a PI easily using the factory function ProcessingInstruction(), but it doesn't get added into the elementtree. I can add it manually, but I can't figure out how to add it above...
Hello, I'm having a hard time finding a good, basic example of how to parse XML in python using Element Tree. From what I can find, this appears to be the easiest library to use for parsing XML. Here is a sample of the XML I'm working with: <timeSeriesResponse> <queryInfo> <locationParam>01474500</locationParam> <va...
