Ignore namespace in xpath selector not working

I have the XML below and want to select the value of the name attribute of element category.

I looked here and here and here.

I actually want xpath 1.0, so I tried:
/result/products/product/*:[local-name() = 'categories']/*:[local-name() = 'category']/@name

Since that didn't work I also just attempted xpath 2.0:
/result/products/product/*:categories/*:category/@name

If I remove the namespace prefixes from the source document, the selector /result/products/product/categories/category/@name returns the correct value.

So, how can I ignore namespaces in my selectors?

<result version="3.0"
    xmlns="urn:com:tradedoubler:pf:model:xml:output"
    xmlns:ns2="urn:com:tradedoubler:pf:model:xml:common">
    <products>
        <product>
            <ns2:name>MY name</ns2:name>
            <ns2:productImage>https://www.google.com/assets/1400x1960/1519833875/18053428-6dv7qPqW.jpg</ns2:productImage>
            <ns2:categories>
                <ns2:category name="Living&gt;Curtains&gt;Curtains"></ns2:category>
            </ns2:categories>

        </product>
    </products>
</result>

Your XPath expression is wrong: you have superfluous : in your expression and you also need to take the default namespace xmlns="urn:com:tradedoubler:pf:model:xml:output" into account which affects all children of the <result> element.

So use the following expression:

/*[local-name() = 'result']/*[local-name() = 'products']/*[local-name() = 'product']/*[local-name() = 'categories']/*[local-name() = 'category']/@name

In your XML, all elements which don’t have a namespace prefix are in the default namespace, which is xmlns="urn:com:tradedoubler:pf:model:xml:output".

So you need to fix your xpath to introduce this namespace. A good practice is to use an extra namespace prefix for that, for instance:

xmlns:o="urn:com:tradedoubler:pf:model:xml:output"

Your xpath becomes:

/o:result/o:products/o:product/*:[local-name() = 'categories']/*:[local-name() = 'category']/@name

You can also use the ns2 namespace:

/o:result/o:products/o:product/ns2:categories/ns2:category/@name
