## Enumeration Type Documentation

enum axis2_scopes

Axis2 scopes.

Possible scope value for Axis2

Enumerator:

  AXIS2_SCOPE_REQUEST | Request scope
  AXIS2_SCOPE_SESSION | Session scope
  AXIS2_SCOPE_APPLICATION | Application scope

## Function Documentation

AXIS2_EXTERN axis2_char_t** axutil_parse_request_url_for_svc_and_op | ( | const axutil_env_t * | env,
|  | const axis2_char_t * | request |
| ) |  |  |

This function allows users to resolve the service and op from the url. It returns an array of 2 elements of axis2_char_t arrays (strings). The caller is responsible to free the memory allocated by the function for the return value.

Parameters:

  | env | pointer to environment struct
  | request | url

Returns:
  axis2_char_t ** `axis2_char_t **```

AXIS2_EXTERN axis2_status_t axutil_parse_rest_url_for_params | ( | const axutil_env_t * | env,
|  | const axis2_char_t * | tmpl,
|  | const axis2_char_t * | url,
|  | int * | match_count,
|  | axis2_char_t **** | matches |
| ) |  |  |

This function allows the user match a REST URL template with the Request URL. It returns a 3-dimensional array with pairs of elements of axis2_char_t arrays (strings). The caller is responsible to free the memory allocated by the function for the return value.

Parameters:

  | env | pointer to environment struct
  | tmpl | Template to Match
  | url | Request URL
  | match_count | variable to store match count
  | matches | axis2_char_t *** `axis2_char_t ***```

Returns:
  ``AXIS2_SUCCESS if all matches were found or AXIS2_FAILURE.``

AXIS2_EXTERN axis2_char_t* axutil_xml_quote_string | ( | const axutil_env_t * | env,
|  | const axis2_char_t * | s,
|  | axis2_bool_t | quotes |
| ) |  |  |

Quotes an XML string. Replace '<', '>', and '&' with '<', '>', and '&'. If quotes is true, then replace '"' with '"'.

Parameters:

  | env | pointer to environment struct
  | s | string to be quoted
  | quotes | if AXIS2_TRUE then replace '"' with '"'. quotes is typically set to true for XML strings that will occur within double quotes -- attribute values.

Returns:
  Encoded string if there are characters to be encoded, else NULL. The caller is responsible to free the memory allocated by the function for the return value
