Re: [xml] parent node property

["Lav Mehrotra" <l mehrotra zensar com>]

Jagdev ,

 

Ur XML seems somewhat like………

 

<Crime> Crime_Value

     <Assault> Assault_Value </Assault>

     <Murder> Murder_Value </Murder >

     <computer_crime> computer_crime _Value </computer_crime >

     <theft>theft_Value </theft >

      .

      .

      .    

</Crime>

 

 

 

 

I guess u r using

 

(par_node->content)  or xmlNodeGetContent(par_node) which gives the combined string concatenated values of all children of par_node

 

(xmlNodeGetContent  API in Tree Module says ……….

Read the value of a node, this can be either the text carried directly by this node if it's a TEXT node or the aggregate string of the values carried by this node child's (TEXT and ENTITY_REF). Entity references are substituted

 

 

Remember always that TEXT content of a Xml Node is also a Child Node .

 

Use xmlNodeListGetString() API……….

 

So  to get only “Crime_Value” content  pass the 1^st child of par_node to xmlNodeListGetString() API like this

 

xmlChar* pszCrimeContent  = xmlNodeListGetString(doc, par_node->children , 1)

 

 

Remember also to free the returned string using xmlFree() as it is allocated on heap via xmlNodeListGetString()

 

xmlChar* pszCrimeContent = NULL;

pszCrimeContent = xmlNodeListGetString(ptrXMLDoc , par_node->children , 1 );

if (pszCrimeContent)

{

            printf(“Value of <Crime>  = %s”, (const char*) pszCrimeContent);

            xmlFree(pszCrimeContent);

           pszCrimeContent = NULL;

}

 

 

 

 

Regds,

Dear all

 

I am trying to build a parent-child array from an xml hierarchy.

So the array is {child value: parent value} eg {assault: crime}, {murder:crime}, {theft:crime} etc

I get the parent of a current node using par_node=cur_node->parent

 

but instead of giving me the name of the first element, its giving me all of the children as well.

 

What its giving me:

 

:0.000000: 0},{assault:

      crime

        murder

        computer_crime

        theft

        drug_trafficking

        sexual_assault

        assault

        torture

        kidnapping

        arson

        gang_activity

       

          criminal

          name

etc

 

What I would like:

{assault:crime}

 

Is there anyway I can just retrieve  the first name value ie crime?

 

Thank you for your help.
