Get Element value with minidom with Python

Question

I am creating a GUI frontend for the Eve Online API in Python   I have successfully pulled the XML data from their server   I am trying to grab the value from a node called  name    from xml dom minidom import parse dom   parse  C   eve xml   name   dom getElementsByTagName  name   print name   This seems to find the node  but the output is below     lt DOM Element  name at 0x11e6d28 gt     How could I get it to print the value of the node

you can use something like this It worked out for me  doc   parse  C   eve xml   my node list   doc getElementsByTagName  name   my n node   my node list 0  my child   my n node firstChild my text   my child data  print my text

The question has been answered  my contribution consists in clarifying one thing that may confuse beginners   Some of the suggested and correct answers used firstChild data and others used firstChild nodeValue instead  In case you are wondering what is the different between them  you should remember they do the same thing because nodeValue is just an alias for data   The reference to my statement can be found as a comment on the source code of minidom       nodeValue is an alias for data

Here is a slightly modified answer of Henrik s for multiple nodes  ie  when getElementsByTagName returns more than one instance   images   xml getElementsByTagName  imageUrl   for i in images      print     join t nodeValue for t in i childNodes if t nodeType    t TEXT NODE

It should just be  name 0  firstChild nodeValue

I had a similar case  what worked for me was   name firstChild childNodes 0  data  XML is supposed to be simple and it really is and I don t know why python s minidom did it so complicated    but it s how it s made

The above answer is correct  namely   name 0  firstChild nodeValue   However for me  like others  my value was further down the tree   name 0  firstChild firstChild nodeValue   To find this I used the following   def scandown  elements  indent        for el in elements          print         indent    nodeName      str el nodeName            print         indent    nodeValue      str el nodeValue            print         indent    childNodes      str el childNodes            scandown el childNodes  indent   1   scandown  doc getElementsByTagName  text    0     Running this for my simple SVG file created with Inkscape this gave me   nodeName  text nodeValue  None childNodes    lt DOM Element  tspan at 0x10392c6d0 gt      nodeName  tspan    nodeValue  None    childNodes    lt DOM Text node   MY STRING   gt         nodeName   text       nodeValue  MY STRING       childNodes     nodeName  text nodeValue  None childNodes    lt DOM Element  tspan at 0x10392c800 gt      nodeName  tspan    nodeValue  None    childNodes    lt DOM Text node   MY WORDS   gt         nodeName   text       nodeValue  MY WORDS       childNodes       I used xml dom minidom  the various fields are explained on this page  MiniDom Python

I know this question is pretty old now  but I thought you might have an easier time with ElementTree  from xml etree import ElementTree as ET import datetime  f   ET XML data   for element in f      if element tag     currentTime             Handle time data was pulled         currentTime   datetime datetime strptime element text    Y- m- d  H  M  S       if element tag     cachedUntil             Handle time until next allowed update         cachedUntil   datetime datetime strptime element text    Y- m- d  H  M  S       if element tag     result             Process list of skills         pass   I know that s not super specific  but I just discovered it  and so far it s a lot easier to get my head around than the minidom  since so many nodes are essentially white space    For instance  you have the tag name and the actual text together  just as you d probably expect    gt  gt  gt  element 0   lt Element currentTime at 40984d0 gt   gt  gt  gt  element 0  tag  currentTime   gt  gt  gt  element 0  text  2010-04-12 02 45 45 e

Probably something like this if it s the text part you want     from xml dom minidom import parse dom   parse  C   eve xml   name   dom getElementsByTagName  name    print     join t nodeValue for t in name 0  childNodes if t nodeType    t TEXT NODE    The text part of a node is considered a node in itself placed as a child-node of the one you asked for  Thus you will want to go through all its children and find all child nodes that are text nodes  A node can have several text nodes  eg    lt name gt    blabla    lt somestuff gt asdf lt  somestuff gt    znylpx  lt  name gt    You want both  blabla  and  znylpx   hence the     join    You might want to replace the space with a newline or so  or perhaps by nothing

It s a tree  and there may be nested elements  Try   def innerText self  sep          t          for curNode in self childNodes          if  curNode nodeType    Node TEXT NODE               t    sep   curNode nodeValue         elif  curNode nodeType    Node ELEMENT NODE               t    sep   curNode innerText sep sep      return t
