Hi,

Could you please help me with an api to get the Tagpath from a confd\_hkeypath\_t?

Eg:  
If below is the confd\_hkeypath  
“/hosts/host{buzz}/interfaces/interface{1/1/1}”;

I need the output of the api as below without the keys  
“/hosts/host/interfaces/interface”;

Thanks in advance.  
Ramishet

Hello,

i believe there is no explicit API/procedure to do it “automatically”.

You can easily get it by iterating the input keypath, and copying only the C\_XMLTAG elements to the output…

pseudo code:

```
int output_len = 0;
for (i = 0; i < input->len; i++) {
    if (C_XMLTAG == input->v[i][0].type) {
        confd_value_dup_to(&input->v[i][0], &output->v[output_len++][0]);
    }
}
output->len = output_len;
```

in addition, whenever working with artificial keypaths created in custom code, for safety reasons it might be a good idea to set/add a border values not occupied by keypath “tags” to `C_NOEXISTS`… (e.g. setting `CONFD_SET_NOEXISTS(&output->v[output->len][0])` etc.

(depending on what you do with the output keypath, for the output key to be a “proper one” that can be safely passed to e.g. `confd_free_hkeypath()`, `confd_hkeypath_dup()`, etc.)
