Re: [Wtp-wst-dev] Question for XML parsing

[Lawrence Mandel <lmandel@xxxxxxxxxx>]

1) Depending on how the document is
parsed or if you're simply passed a model you may need to store the attribute
values for comparison or simply retrieve them from the existing model.

2) This depends on the library you're
using to parse the document (are you using JAXP? Xerces?) and can be done
by skipping the element during parse time or by removing the element from
the model after the model has been created.

Subject	[Wtp-wst-dev] Question for XML parsing

Hi,
 
I'm parsing an XML file, there
is an element named <tl1_message> inside this file, it looks like:
 
<tl1_message>
    <tl1_message_type>
        ..
        ..
        ..
    </tl1_message_type>
    <prod_rel name="ABC" start_rel="aa"
end_rel="bb"/>
    <prod_rel name="XYZ" start_rel="cc"
end_rel="dd"/>
    <other elements.../>
</tl1_message>
This is my requirements:

1). if ABC = XYZ and either bb or dd greater than 6.0, then
<tl1_message>
    <tl1_message_type>
        ..
        ..
        ..
    </tl1_message_type>
    <prod_rel name="ABC"/>
    <other elements.../>
</tl1_message>
 
2). if ABC != XYZ and both bb
and dd are less than 3.0, then
the entire element <tl1_message> should be removed.
My difficulty is:
1). How to compare bb and dd, they are in different element(in the same
level).
2). How to delete the entire element in this case.
 
Thanks
