[sysrepo-devel] sr_xpath_key_value() changes xpath value

[Milan Lenčo]

Hi Jimmy,


the functions from sysrepo/xpath.h do modify the xpath in order to avoid any string duplications. You can always go back to the original xpath using sr_xpath_recover.

Unit tests might help you to better understand the use of sysrepo xpath utilities: tests/xpath_utils_test.c


Regards,

Milan

Hi,
When I call

char *sr_xpath_key_value(char *xpath, const char *node_name, const char *key_name, sr_xpath_ctx_t *state);

the xpath passed in seems be changed. It truncates the string after the key. Is this expected? I need to duplicate the xpath, in order to preserve the original string.

regards,
Jimmy
