Description:
Read property values from node strings.
Syntax:
xs.property(n,v)
Note:
The function returns values under node n in node strings xs. Set n’s value as v if string parameter v is present, and delete n if v is absent.
Parameter:
xs |
Node strings, whose format is“name1=value1 name2=value2...” |
n |
Node string name; return a table sequence made up of all properties when it is absent |
v |
Null or a string |
Option:
@c |
Separate node strings by commas or semicolons; use spaces by default |
@j |
Use colons to separate node string name and its value; use the equal sign by default |
@q |
Enclose values by double quotation marks |
@v |
Read the string and then parse it into value; return a sequence by default |
Return value:
A value/a sequence
Example:
A |
|
|
1 |
color=red size=20 price=500 |
|
2 |
=A1.property("color","blue") |
Change the value of node string named “color” into “blue” . |
3 |
=A1.property@q("size") |
Enclose the value with double quotation marks. |
4 |
=A1.property@v("size") |
Read the string first and then parse it into a value. |
5 |
color:red;size:20;price:500 |
|
6 |
=A5.property@cj("color",) |
Use @c option to separate node string by semicolons; use @j to separate node string name and value by colon; since the value of “color” is null, delete the node from the node strings. |
