I'm trying to remove all the project1 nodes (along with their child elements) from the below sample xml document ( original document is about 30 GB ) using SAX parser.It would be fine to have a separate modified file or ok with the in-line edit. sample.xml <ROOT> <test src="http://dfs.com">Hi</test> <project1>This is old data<foo></foo></project1> <bar> <project1>ty</project1> <foo></foo> </bar> </ROOT> Here is my attempt.. parser.py from xml.sax.handler import ContentHandler import xml.sax class MyHandler(xml.sax.handler.ContentHandler): def __init__(self, out_file): self._charBuffer = []

I am attempting to read a large XML document and I wanted to do it in chunks vs XmlDocument 's way of reading the entire file into memory. I know I can use XmlTextReader to do this but I was wondering if anyone has used SAX for .NET? I know Java developers swear by it and I was wondering if it is worth giving it a try and if so what are the benefits in using it. I am looking for specifics. If you're talking about SAX for .NET , the project doesn't appear to be maintained. The last release was more than 2 years ago. Maybe they got it perfect on the last release, but I wouldn't bet on it. The

When using SAX to parse an XML file in Java, what is the difference between the parameters localname and qname in SAX methods such as startElement(String uri, String localName,String qName, Attributes attributes) ? The qualified name includes both the namespace prefix and the local name: att1 and foo:att2 . Sample XML <root xmlns="http://www.example.com/DEFAULT" att1="Hello" xmlns:foo="http://www.example.com/FOO" foo:att2="World"/> Java Code: att1 Attributes without a namespace prefix do not pick up the default namespace. This means while the namespace for the root element is "http://www

This is a simple question, but one I cannot find the answer to. I have an XSLT 2.0 stylesheet that I'm trying to process in Java. It relies on XSL elements from Saxon. My current class works fine with simple XSLT 1.0, but I'm getting errors about unrecognized elements with my 2.0 XSLT built with Saxon. I cannot figure out how to tell Java to use Saxon as the processor. I'm using javax.xml.transform in my class. Is this a property I can set? What do I set it to? Thanks! Edited I figured out how to set the property to use Saxon, but now I'm getting this error. Provider net.sf.saxon

Python has several ways to parse XML... I understand the very basics of parsing with SAX . It functions as a stream parser, with an event-driven API. I understand the DOM parser also. It reads the XML into memory and converts it to objects that can be accessed with Python. Generally speaking, it was easy to choose between the two depending on what you needed to do, memory constraints, performance, etc. (Hopefully I'm correct so far.) Since Python 2.5, we also have ElementTree . How does this compare to DOM and SAX? Which is it more similar to? Why is it better than the previous parsers?

I have these XML on a URL <?xml version="1.0" encoding="ISO-8859-1" ?> <Phonebook> <PhonebookEntry> <firstname>John</firstname> <lastname>Connor</lastname> <Address>5,Downing Street</Address> <Phone loc="home">9875674567</Phone> <Phone loc="work">9875674567</Phone> <Phone loc="mobile">78654562341</Phone> </PhonebookEntry> <PhonebookEntry> <firstname>John</firstname> <lastname>Smith</lastname> <Address>6,Downing Street</Address> <Phone loc="home">678-56-home</Phone> <Phone loc="work">678-59-work</Phone> <Phone loc="mobile">678-85-mobile</Phone> </PhonebookEntry> </Phonebook> I was able to

I have a contact that is experiencing trouble with SAX when parsing RSS and Atom files. According to him, it's as if text coming from the Item elements is truncated at an apostrophe or sometimes an accented character. There seems to be a problem with encoding too. I've given SAX a try and I have some truncating taking place too but haven't been able to dig further. I'd appreciate some suggestions if someone out there has tackled this before. This is the code that's being used in the ContentHandler: public void characters( char[], int start, int end ) throws SAXException { // link = new String
