Should Xpath select nodes containing default values??

aman.coe · Oct 21, 2005

hello all

Consider this xml file:

<root>
<body>
<ElementX id="X1" Xproperty="X_Default_Value" />
<ElementX id="X2" />
</body>
</root>

Here for the element of type 'ElementX' the attribute 'Xproperty' has
default value as 'X_Default_Value'.

Now the question is whether the following Xpath Expression
"//ElementX[@Xproperty='X_Default_Value']" would select a single node
ie ElementX with id as 'X1' or 2 ElementX nodes.

Thanx in advance.

<ElementX id="X2" />

</root>

default value as 'X_Default_Value'.

Where is the DOCTYPE declaration then?

Now the question is whether the following Xpath Expression
"//ElementX[@Xproperty='X_Default_Value']" would select a single node
ie ElementX with id as 'X1' or 2 ElementX nodes.

It will depend on the parser or implemention settings whether it reads a
DTD or schema and adds default values defined there. If those are added
then the XPath expression will select two element nodes.
