Hi Dave, I created a xsd that has an element called script. The intent is to allow users to send us javascript that is encoded with CDATA tags.
In the attached files you can see that I set the script variable as follows:
cdataObj = Cdata()
script='''<![CDATA[
var x, text;
// Get the value of the input field with id="numb"
x = document.getElementById("numb one").value;
// If x is Not a Number or less than one or greater than 10
if (isNaN(x) || x < 1 || x > 10) {
text = "Input not valid";
} else {
text = "Input OK";
}
document.getElementById("demo").innerHTML = text;
]]>'''
cdataObj.set_script(script)
I exported it:
cdataObj.export(sys.stdout, 0, name_='cdata')
And got the following:
<cdata:cdata xmlns:cdata="urn:cdata">
<cdata:script><![CDATA[
var x, text;
// Get the value of the input field with id="numb"
x = document.getElementById("numb one").value;
// If x is Not a Number or less than one or greater than 10
if (isNaN(x) || x < 1 || x > 10) {
text = "Input not valid";
} else {
text = "Input OK";
}
document.getElementById("demo").innerHTML = text;
]]></cdata:script>
</cdata:cdata>
Note that the CDATA wrappers have been encoded <![CDATA[ has been changed
to <![CDATA[ and ]]> has been changed to ]]>
Also notice that the < and > signs in the java script have also been
encoded. I believe there should be code to check for the CDATA tags and not
xml encode it if they exist. I'll try to track this down in the code but I
wanted to make sure this wasn't done on purpose.
There is another problem with CDATA. If I create an xml string with CDATA
and parse it like this:
xml='''
<cdata:cdata xmlns:cdata="urn:cdata">
<cdata:script><![CDATA[
var x, text;
// Get the value of the input field with id="numb"
x = document.getElementById("numb one").value;
// If x is Not a Number or less than one or greater than 10
if (isNaN(x) || x < 1 || x > 10) {
text = "Input not valid";
} else {
text = "Input OK";
}
document.getElementById("demo").innerHTML = text;
]]></cdata:script>
</cdata:cdata>
'''
cdata.parseString(xml)
It incorrectly strips out the CDATA tags:
parseString spits out xml with the CDATA tags removed.:
<?xml version="1.0" ?>
<cdata:cdata xmlns:cdata="urn:cdata">
<cdata:script>
var x, text;
// Get the value of the input field with id="numb"
x = document.getElementById("numb one").value;
// If x is Not a Number or less than one or greater than 10
if (isNaN(x) || x &lt; 1 || x &gt; 10) {
text = "Input not valid";
} else {
text = "Input OK";
}
document.getElementById("demo").innerHTML = text;
</cdata:script>
</cdata:cdata>
And on printing the script specifically, I also don't have CDATA tags
anymore and the < and > are xml encoded.
print cdataObj.get_script()
var x, text;
// Get the value of the input field with id="numb"
x = document.getElementById("numb one").value;
// If x is Not a Number or less than one or greater than 10
if (isNaN(x) || x < 1 || x > 10) {
text = "Input not valid";
} else {
text = "Input OK";
}
document.getElementById("demo").innerHTML = text;
I'll see if I can track this down also. If you could give me a hint of
where to look that would be helpful.
Thanks,
George
