Hi David,
Thanks for the information.
Actually what i wanto achieve is to read the following xml file:
<?xml version="1.0" encoding="utf-8"?>
<operating_system>
<unix_80sp1>
<tests type="quick_sanity_test">
<prerequisitescript>preparequicksanityscript</prerequisitescript>
<acbuildpath>acbuildpath</acbuildpath>
<testsuitscript>test quick sanity script</testsuitscript>
<testdir>quick sanity dir</testdir>
</tests>
<machine_name>u80sp1_L004</machine_name>
<machine_name>u80sp1_L005</machine_name>
<machine_name>xyz.pxy.dxe.cde</machine_name>
<vmware id="155.35.3.55">144.35.3.90</vmware>
<vmware id="155.35.3.56">144.35.3.91</vmware>
</unix_80sp1>
</operating_system>
For a single tag i am able to get the values for e.g:
<acbuildpath>acbuildpath</acbuildpath>
by using the following piece of code:
nodeList = document.getElementsByTagName("acbuildpath")
for i in range(nodeList.getLength()):
node = nodeList.item(i)
if node.getNodeType() == Node.ELEMENT_NODE:
children = node.getChildNodes()
for j in range(children.getLength()):
thisChild = children.item(j)
if (thisChild.getNodeType() == Node.TEXT_NODE):
acbuildpath = thisChild.getNodeValue()
so now acbuildpath gives me the value in tag acbuild path:
This goes fine.
Now in the same xml file there is a tag "machine_name". This tag appears
thrice in the xml file .What i want to achieve is read all these values in a
list variable. So i am not sure what correction i should do in the code so
that i can capture all the three "machine_name" tag values from the
mentioned xml file.
Also there is a tag named as "vmware" in the xml file .The format of the tag
is <vmware id="155.35.3.55">144.35.3.90</vmware>
There are two tags like this .
Here in the tag the first ip is the attribute of the tag , and second is
the value of the tag. I want to read all attributes into a list
and all the values into another list.(as there are two such tags).
So what correction i need to do in the above code to achieve this.
Kinldy suggest(it would be a time saver). I am also trying to solve in
between by looking in the internet materials that you have suggested.
Regards
Sangram
