Re: How to get an Xpath?

I have attached the spsDefs.hxx file. lpXPath is a char* which takes valid XPath. But but there is a limitation with the code that I sent you, it can only return values for a node or attributes. I have never tried querying for a comment within a node,so am not sure whether it will work or not.

Cheers,

Hi Amit,

Thanks for the code, It would be helpful if you send me the include file "spsDefs.hxx".

I have a question, in the code the function queryValue takes input lpXPath.

SPS_CHAR* XMLParser::queryValue(SPS_CHAR* lpXPath)

So what should be the parameter , Can I send "UPDATE FROM " here ?

I am still exploring other possibilities.

Thanks

Hi Praveen,

    You need to provide the XML data/stream, it can be via XML File or in memory. A sample has been provided with Xalan for XML data via file and for XML data stored in a memory you can use 'MemBufInputSource'. I am enclosing a .cxx and .hxx file while might be of some help to you.

Hope this helps.

Cheers,

Amit Dang

I have compiled the Xalan 1.9 C++ in Sol 2.8.

Samples are aslo compiled and I am able to run the EXE's.

Imagine I have an XML file as follows

<PML>
    <EC>
            <TN>100-111-99</TN>
            <LVL1>
                <AS>aaa</AS>
            </LVL1>
            <LV1>
                <NU>AB/10</NU>
            </LV1>
            <LV1>

                <EMP>101</EMP>
                <DT>10012005</DT>
            </LV1>

    </EC>

</PML>

If I give an input as "UPDATE FROM" the output I should get is "PML:EC.TN" and "PML:EC.LV1"

Similarly if I give an input as "DELETE" I should get the output as "PML:EC.LVL1" and "PML:EC.LV1[2]"

Is there a way to get this from the Xalan API's ?

If you have any sample program please do send me...

I checked the sample program present in Xalan , it takes three parameters "XML file" , "Context" and "XPATH" .

I am not able to understand what should go as input in case of "context " and "XPATH".

Thanks
