IF PositionSharp >= 0 THEN

Flow creation steps
URL parameters begin with "?". This flow uses that rule.
The Parse text Action searches for the position of "?" position in the Parse text Action.
This action is set up one more time, so we change the name of the Variables produced to PositionQuestion.
| Parameter | Value |
|---|---|
| Text to parse | URL to remove GET parameters. |
| Text to find | ? |
| Is regular expression | OFF |
| Start parsing at position | 0 |
| First occurrence only | ON |
Then use the second Parse text Action to find the position of the "#". (Anchor position).
The Variables produced is renamed PositionSharp.
| Parameter | Value |
|---|---|
| Text to parse | URL to remove GET parameters. |
| Text to find | # |
| Is regular expression | OFF |
| Start parsing at position | 0 |
| First occurrence only | ON |
Next, Set up an If Action to control the URL parameter ("?") to avoid errors.
This If Action is not necessary in cases where the URL parameter("?") is not necessary in cases where the URL parameter("?") is always present.
| Parameter | Value |
|---|---|
| First operand | %PositionQuestion% |
| Operator | Greater then or equal to(>=) |
| Second operand | 0 |
Set up an additional If Action inside the If Action. This is for cases where there is no anchor ("#").
| Parameter | Value |
|---|---|
| First operand | %PositionSharp% |
| Operator | Greater then or equal to(>=) |
| Second operand | 0 |
The second If Action adds an Else Action to make it look like the one below.
Set up Get subtext Action in the second If Action.
| Parameter | Value |
|---|---|
| Original text | URL to remove GET parameters. |
| Start index | Character position |
| Character position | %PositionQuestion + 1% |
| Lenght | Number of chars |
| Number of chars | %PositionSharp - PositionQuestion - 1% |
Set up Get subtext Action in Else Action as well.
The second one will automatically change the Variables produced name, so change it to the same (Subtext) as the first one.
| Parameter | Value |
|---|---|
| Original text | URL to remove GET parameters. |
| Start index | Character position |
| Character position | %PositionQuestion + 1% |
| Lenght | End of text |
Executing this flow will set the Variables produced(Subtext) of Get subtext Action to the URL with the GET parameter removed.
