Retrieving Attributes ar01s07.htmlPrev    ar01s09.htmlNext Retrieving Attributes
Retrieving the value of an attribute is similar to the previous
    example in which we retrieved a node's text contents. In this case we'll
      extract the value of the 
URI we added in the previous
      section. Full code: 
apg.htmlAppendix G, Code for Retrieving Attribute Value Example .
      The initial steps for this example are similar to the previous ones: parse
      the doc, find the element you are interested in, then enter a function to
      carry out the specific task required. In this case, we call
      
getReference:
      
void
getReference (xmlDocPtr doc, xmlNodePtr cur) {
	xmlChar *uri;
	cur = cur->xmlChildrenNode;
	while (cur != NULL) {
	    if ((!xmlStrcmp(cur->name, (const xmlChar *)"reference"))) {
		   
1 uri = xmlGetProp(cur, "uri");
		    printf("uri: %s\n", uri);
		    xmlFree(uri);
	    }
	    cur = cur->next;
	}
	return;
}
      
    
      
#getattributevalue1  	    The key function is 
http://xmlsoft.org/html/libxml-tree.html#XMLGETPROPxmlGetProp , which returns an
      
xmlChar containing the attribute's value. In this case,
					   we just print it out.
      
[Note] Note 	  If you are using a 
DTD that declares a fixed or
	  default value for the attribute, this function will retrieve it.
