带有最小化的python xml解析

Question

I have this XML file and I need to read the value from Sync and Event in the same order as in the XML file.

<Episode>
<Section type="report" startTime="0" endTime="263.035">
    <Turn startTime="0" endTime="4.844" speaker="spk1">
        <Sync time="0"/>
        aaaaa
    </Turn>
    <Turn speaker="spk2" startTime="4.844" endTime="15.531">
        <Sync time="4.844"/>
        bbbbb
        <Event desc="poz" type="noise" extent="begin"/>
        ccccc
        <Event desc="poz" type="noise" extent="end"/>
        ddddd

    <Sync time="12.210"/>
        eeeee 
    </Turn>
    <Turn speaker="spk1" startTime="15.531" endTime="17.549">
        <Event desc="poz" type="noise" extent="begin"/>
        fffff
    </Turn>
</Section>
</Episode>

And I need this output:

aaaaa
bbbbb
ccccc
ddddd
eeeee
fffff

Is there any solution? Thank you.

Answer 1

Use the builtin sax parser:

from xml import sax

class EpisodeContentHandler(sax.ContentHandler):
    def characters(self, content):
        content = content.strip()
        if content:
            print content

with open("Episode.xml") as f:
    sax.parse(f, EpisodeContentHandler())

Unless you're somehow limited to using Minidom, try using 'ElementTree' as Martijn suggested. From my personal experience, it's much easier to use. You can find it's documentation here

For your problem, you can try something like this:

import xml.etree.ElementTree as ET

# Get the tree structure of the XML
tree = ET.parse("data.xml")
# Get the root/first tag in the tree
root = tree.getroot()
# Ge all elements with interesting tags
for child in root.findall("Sync"):
   print child.text

Sidenote: child.attrib is a map to all the tag's attributes.

Answer 3

If you insist on using minidom:

elements = minidom.parseString(xml).getElementsByTagName('*') # where xml is your input xml
for el in elements:
    if el.localName == 'Sync' or el.localName == 'Event':
        print el.nextSibling.nodeValue.strip()

This will print:

aaaaa
bbbbb
ccccc
ddddd
eeeee
fffff
