lxml etree xmlparser remove unwanted namespace

by

import io import lxml.etree as ET content=””‘\ <Envelope xmlns=”http://www.example.com/zzz/yyy”> <Header> <Version>1</Version> </Header> <Body> some stuff </Body> </Envelope> ”’ dom = ET.parse(io.BytesIO(content)) You can find namespace-aware nodes using the xpath method: body=dom.xpath(‘//ns:Body’,namespaces={‘ns’:’http://www.example.com/zzz/yyy’}) print(body) # [<Element {http://www.example.com/zzz/yyy}Body at 90b2d4c>] If you really want to remove namespaces, you could use an XSL transformation: # http://wiki.tei-c.org/index.php/Remove-Namespaces.xsl xslt=””‘<xsl:stylesheet version=”1.0″ xmlns:xsl=”http://www.w3.org/1999/XSL/Transform”> … Read more

What are the differences between lxml and ElementTree?

by

ElementTree comes built-in with the Python standard library which includes other data modules types such as json and csv. This means the module ships with each installation of Python. For most normal XML operations including building document trees and simple searching and parsing of element attributes and node values, even namespaces, ElementTree is a reliable … Read more

Use xml.etree.ElementTree to print nicely formatted xml files [duplicate]

by

You can use the function toprettyxml() from xml.dom.minidom in order to do that: def prettify(elem): “””Return a pretty-printed XML string for the Element. “”” rough_string = ElementTree.tostring(elem, ‘utf-8’) reparsed = minidom.parseString(rough_string) return reparsed.toprettyxml(indent=”\t”) The idea is to print your Element in a string, parse it using minidom and convert it again in XML using the … Read more

Parsing XML in Python using ElementTree example

by

So I have ElementTree 1.2.6 on my box now, and ran the following code against the XML chunk you posted: import elementtree.ElementTree as ET tree = ET.parse(“test.xml”) doc = tree.getroot() thingy = doc.find(‘timeSeries’) print thingy.attrib and got the following back: {‘name’: ‘NWIS Time Series Instantaneous Values’} It appears to have found the timeSeries element without … Read more

How do I get Python’s ElementTree to pretty print to an XML file?

by

Whatever your XML string is, you can write it to the file of your choice by opening a file for writing and writing the string to the file. from xml.dom import minidom xmlstr = minidom.parseString(ET.tostring(root)).toprettyxml(indent=” “) with open(“New_Database.xml”, “w”) as f: f.write(xmlstr) There is one possible complication, especially in Python 2, which is both less … Read more

access ElementTree node parent node

by

There’s no direct support in the form of a parent attribute, but you can perhaps use the patterns described here to achieve the desired effect. The following one-liner is suggested (updated from the linked-to post to Python 3.8) to create a child-to-parent mapping for a whole tree, using the method xml.etree.ElementTree.Element.iter: parent_map = {c: p … Read more

XML parsing – ElementTree vs SAX and DOM

by

ElementTree is much easier to use, because it represents an XML tree (basically) as a structure of lists, and attributes are represented as dictionaries. ElementTree needs much less memory for XML trees than DOM (and thus is faster), and the parsing overhead via iterparse is comparable to SAX. Additionally, iterparse returns partial structures, and you … Read more

How to write XML declaration using xml.etree.ElementTree

by

I am surprised to find that there doesn’t seem to be a way with ElementTree.tostring(). You can however use ElementTree.ElementTree.write() to write your XML document to a fake file: from io import BytesIO from xml.etree import ElementTree as ET document = ET.Element(‘outer’) node = ET.SubElement(document, ‘inner’) et = ET.ElementTree(document) f = BytesIO() et.write(f, encoding=’utf-8′, xml_declaration=True) … Read more
