### Description
Examples of [RFC7840](https://tools.ietf.org/html/rfc7840#section-7) contains this response: ```xml <locationResponse xmlns="urn:ietf:params:xml:ns:geopriv:held"> <locationUriSet expires="2006-01-01T13:00:00.0Z"> <locationURI> https://ls.example.com:9768/357yc6s64ceyoiuy5ax3o </locationURI> <locationURI> sip:9769+357yc6s64ceyoiuy5ax3o@ls.example.com </locationURI> </locationUriSet>
<routingInformation xmlns="urn:ietf:params:xml:ns:geopriv:held:ri"> <service serviceUri="urn:service:sos"> <dest>sip:112@example.com</dest> <dest>sips:112@example.com</dest> <dest>xmpp:112@example.com</dest> </service> </routingInformation>
</locationResponse> ```
When the `lost` module receives such a response, then generate this message ``` http_client [functions.c:299]: curL_query_url(): Malformed URL used in http client (url: https://ls.example.com:9768/357yc6s64ceyoiuy5ax3o ) lost [functions.c:325]: lost_held_function(): dereferencing location failed: 3 ```
This error is fixed when if I strip spaces in a string of `locationURI` element.
### Troubleshooting
#### Reproduction
Send xml eample from RFC as responce for `lost_held_query` function call.
### Possible Solutions
Strip leading and trailing spaces of `locationURI` element. Maybe the required changes here https://github.com/kamailio/kamailio/blob/master/src/modules/lost/functions....
