Using libxml2 invalid conversion from const char* to const xmlChar* error

Hi I am having this issue and not sure how to resolve.

I am having to compile my code using g++ instead of gcc for a number of reasons, however I am getting:

main.cpp:129: error: invalid conversion from ‘const char*’ to ‘const xmlChar*’
main.cpp:129: error: initializing argument 2 of ‘xmlChar* xmlGetProp(xmlNode*, const xmlChar*)’

Code:

void getIngredients (xmlDocPtr doc, xmlNodePtr cur) {
	xmlChar *name;
	cur = cur->xmlChildrenNode;
	while (cur != NULL) {
	    if ((!xmlStrcmp(cur->name, (const xmlChar *)"ingredient"))) {
		    name = xmlGetProp(cur, "name");
		    printf("name: %s\n", name);
		    xmlFree(name);
	    }

Has anyone got any ideas??

Not to worry - sorted it....
xmlGetProp(cur, "name");
"name" needed to be casted so that it said xmlGetProp(cur, (const xmlChar *)"name");

Thanks

Change the offending line to

Code:

     name = xmlGetProp(cur, (const xmlChar *)"name");

The preceding line does exactly the same type of conversion, in a similar context, so I assume it is valid. However, you will need to confirm that (eg through appropriate testing). Shutting the compiler up does not always correspond to doing what is intended.

Grumpy - thanks for that.

Many thanks.

xmlChar is typedef'd as an unsigned char, so it should not be a problem casting between xmlChar * and char *.
