Before you use CXML-GET-ATTRIBUTE, we recommend that you use CXML-GET-ATTRIBUTE-COUNT. This op-code tells you how many attributes are in the element of interest. Then when you use CXML-GET-ATTRIBUTE, you know which attribute you are getting (the first attribute is number 0, the second number 1, etc.). Alternatively, if you know the name of the attribute you want and not the number of the attribute, you can use CXML-GET-ATTRIBUTE-BY-NAME. If you have an unknown number of attributes like this:
and you are searching for a particular attribute, say "xmlns:xsi", you can search for the value with CXML-GET-ATTRIBUTE-BY-NAME, or you can get the count and read the attributes one by one searching for the one you want.
