I am trying to do the folowing with Python:
this is my original xml:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<body start="20.04.2014 10:02:60">
<pricelist>
<item>
<name>LEO - red pen</name>
<price>31,4</price>
<price_snc>0</price_snc>
<price_ao>0</price_ao>
<price_qty>
<item qty="150" price="28.20" />
<item qty="750" price="26.80" />
<item qty="1500" price="25.60" />
</price_qty>
<stock>50</stock>
</item>
</pricelist>
the new xml should look this way:
<pricelist>
<item>
<name>LEO - red pen</name>
<price>31,4</price>
<price_snc>0</price_snc>
<price_ao>0</price_ao>
<price_qty>
<item qty="10" price="31.20" /> **-this is the new line**
<item qty="150" price="28.20" />
<item qty="750" price="26.80" />
<item qty="1500" price="25.60" />
</price_qty>
<stock>50</stock>
</item>
</pricelist>
my code so far:
import xml.etree.cElementTree as ET
from xml.etree.ElementTree import Element, SubElement
tree = ET.ElementTree(file='pricelist.xml')
root = tree.getroot()
pos=0
# price - raise the main price and insert new tier
for elem in tree.iterfind('pricelist/item/price'):
price = elem.text
newprice = (float(price.replace(",", ".")))*1.2
newtier = "NEW TIER"
SubElement(root[0][pos][5], newtier)
pos+=1
tree.write('pricelist.xml', "UTF-8")
result:
...
<price_qty>
<item price="28.20" qty="150" />
<item price="26.80" qty="750" />
<item price="25.60" qty="1500" />
<NEW TIER /></price_qty>
thank you for any help.
Don't use fixed indexing. You already have the item element, so why don't use it?
tree = ET.ElementTree(file='pricelist.xml')
root = tree.getroot()
for elem in tree.iterfind('pricelist/item'):
price = elem.findtext('price')
newprice = float(price.replace(",", ".")) * 1.2
newtier = ET.Element("item", qty="10", price="%.2f" % newprice)
elem.find('price_qty').insert(0, newtier)
tree.write('pricelist.xml', "UTF-8")
