This section describes a number of "helper" functions for formatting and parsing various types of properties for tags in glabels XML file formats.
These functions are basically wrappers to functions from libxml2.
gdouble gl_xml_get_prop_double (xmlNodePtr node, const gchar *property, gdouble default_val);
Return value of property as a double.
node : | the libxml2 xmlNodePtr of the node |
property : | the property name |
default_val : | a default value to return if property not found |
Returns : | the property as a double. |
gboolean gl_xml_get_prop_boolean (xmlNodePtr node, const gchar *property, gboolean default_val);
Return value of property as a boolean.
node : | the libxml2 xmlNodePtr of the node |
property : | the property name |
default_val : | a default value to return if property not found |
Returns : | the property as a boolean. |
gint gl_xml_get_prop_int (xmlNodePtr node, const gchar *property, gint default_val);
Return value of property as an integer.
node : | the libxml2 xmlNodePtr of the node |
property : | the property name |
default_val : | a default value to return if property not found |
Returns : | the property as an integer. |
guint gl_xml_get_prop_uint (xmlNodePtr node, const gchar *property, guint default_val);
Return value of property (usually formatted in hex) as an unsigned integer.
node : | the libxml2 xmlNodePtr of the node |
property : | the property name |
default_val : | a default value to return if property not found |
Returns : | the property as an unsigned integer. |
gdouble gl_xml_get_prop_length (xmlNodePtr node, const gchar *property, gdouble default_val);
Return value of a length property as a double, converting to internal units (points). The property is expected to be formatted as a number followed by a units string. If there is no units string, the length is assumed to be in points. Valid units strings are "pt" for points, "in" for inches, "mm" for millimeters, "cm" for centimeters, and "pc" for picas.
node : | the libxml2 xmlNodePtr of the node |
property : | the property name |
default_val : | a default value to return if property not found |
Returns : | the length in points. |
void gl_xml_set_prop_double (xmlNodePtr node, const gchar *property, gdouble val);
Set a property from a double.
node : | the libxml2 xmlNodePtr of the node |
property : | the property name |
val : | the value to set |
void gl_xml_set_prop_boolean (xmlNodePtr node, const gchar *property, gboolean val);
Set a property from a boolean.
node : | the libxml2 xmlNodePtr of the node |
property : | the property name |
val : | the value to set |
void gl_xml_set_prop_int (xmlNodePtr node, const gchar *property, gint val);
Set a property from an integer.
node : | the libxml2 xmlNodePtr of the node |
property : | the property name |
val : | the value to set |
void gl_xml_set_prop_uint_hex (xmlNodePtr node, const gchar *property, guint val);
Set a property from an unsigned integer and format in hex.
node : | the libxml2 xmlNodePtr of the node |
property : | the property name |
val : | the value to set |
void gl_xml_set_prop_length (xmlNodePtr node, const gchar *property, gdouble val);
Set a property from a length, performing any necessary conversion.
Length properties are formatted as a number followed by a units string.
The units of the formatted property is determined by the most recent call to
gl_xml_set_default_units()
.
node : | the libxml2 xmlNodePtr of the node |
property : | the property name |
val : | the length to set in internal units (points) |
void gl_xml_set_default_units (glUnitsType units);
Set the default units when formatting lengths. See
gl_xml_set_prop_length()
.
units : | default units selection (glUnitsType) |
