iXML - Checking if a specific node exists in XML data

[Former Member]

Hi,

I´m reading XML data by using iXML classes. One XML file I´m reading contains header and

item data.

Right now I´m starting with reading the header attributes and then read all nested nodes and their attribute data. That works all fine, but now I had the error, that the XML file wrongly didn´t contain the items.

My XML reading method then ended up in a dump because the node was null:

l_node = l_iterator->get_next( ).

Can anybody give me an advice, how to check at the beginning of reading my xml data, if a specific node (in my case the node for items) exists in the XML data? If not, I want to stop with an error message. I want to check that at the beginning, before reading all element data, to keep my method structured.

Thank you very much!

Hi,

You can create a filter and set that filter to the iterator. If this is done the iterator returns you only the node with a specific node name or node ID.

You can also check the parsing in the following WIKI code gallery

Subroutines create_set_filter_attribute and parse_xml_file would be helpful.
