Help with capturing and parsing a msdp variable
|
First of all, I'm a novice. I have a lot of msdp-related stuff working on cmud, but there's one that's giving me a lot of problems.
One of the msdp variables coming in contains multiple lines and I'd like to write it to a window. Here's a basic look at the type of thing that's coming in:
| Code: |
\n\r( )==========================================================================( )\n\r
| |\n\r
| |\n\r
| |\n\r
| |\n\r
( )--------------------------------------------------------------------------( )\n\r
|
The number of lines sometimes changes, but I can't get it to work even in a scenario where the lines is constantly 18. I've tried a few different things, with the pattern as SCROLL (.*) and the one in the code below. There's probably a much better way to go about it. Any help would be appreciated.
| Code: |
<trigger type="Telnet" param="69" priority="14520" regex="true" newline="false" prompt="true" enabled="false" id="506">
<pattern>SCROLL(.*)[\n\r]+(.*)[\n\r]+(.*)[\n\r]+(.*)[\n\r]+(.*)[\n\r]+(.*)[\n\r]+(.*)[\n\r]+(.*)[\n\r]+(.*)[\n\r]+(.*)[\n\r]+(.*)[\n\r]+(.*)[\n\r]+(.*)[\n\r]+(.*)[\n\r]+(.*)[\n\r]+(.*)[\n\r]+(.*)[\n\r]+(.*)[\n\r]</pattern>
<value>parseddesc.1 = %1
parseddesc.2 = %2
parseddesc.3 = %3
parseddesc.4 = %4
parseddesc.5 = %5
parseddesc.6 = %6
parseddesc.7 = %7
parseddesc.8 = %8
parseddesc.9 = %9
parseddesc.10 = %10
parseddesc.11 = %11
parseddesc.12 = %12
parseddesc.13 = %13
parseddesc.14 = %14
parseddesc.15 = %15
parseddesc.16 = %16
parseddesc.17 = %17
parseddesc.18 = %18
#clr scroll
#window scroll {%crlf @parseddesc.1 %crlf @parseddesc.2 %crlf @parseddesc.3 %crlf @parseddesc.4 %crlf @parseddesc.5 %crlf @parseddesc.6 %crlf @parseddesc.7 %crlf @parseddesc.8 %crlf @parseddesc.9 %crlf @parseddesc.10 %crlf @parseddesc.11 %crlf @parseddesc.12 %crlf @parseddesc.13 %crlf @parseddesc.14 @parseddesc.15 %crlf @parseddesc.16 %crlf @parseddesc.17 %crlf @parseddesc.18}</value>
</trigger>

You could make use of a #STWIN object to hold the data, which is displayed in the status window.

This should work, but I didn't test the subregex.
| Code: |
<trigger type="Telnet" param="69" priority="14520" regex="true" newline="false" prompt="true" enabled="false" id="506">
<pattern>SCROLL(.*)</pattern>
<value>parsedesc=%subregex(%1,"([^\n\r]*)(?:(\n\r)|\Z)","""\1""(?(2)\|)")
#CLR scroll
#WINDOW scroll {%1}</value>
</trigger> |

Thanks for the quick replies. I tried the xml trigger, but all I get in the window and assigned to parsedesc is an upsidedown L in quotes

I had the mud remove the leading \n\r from the variable so it's coming in like this:
| Code: |
( )==========================================================================( )\n\r
| |\n\r
| |\n\r
| |\n\r
| |\n\r
( )--------------------------------------------------------------------------( )\n\r |
now I get this assigned to the parsedesc variable, but there's a character that looks like an upside down L at the beginning of the line:
| Code: |
"( )==========================================================================( )"
It looks like it's still not handling the \n\r that are coming in properly. Any ideas? |

By the way, I tried holding the data with #STWIN like shalimar suggested, but no dice. It seems like a really simple problem and I just can't figure it out.
I also tried modifying what Vijilante suggested but nothing I try works. |

In order to figure this out you will have to try simpler and simpler things. Let's start with this:
| Code: |
<trigger type="Telnet" param="69" priority="14520" regex="true" newline="false" prompt="true" enabled="false" id="506">
<pattern>SCROLL(.*)</pattern>
<value>parsedesc=%1
#CLR scroll
#WINDOW scroll {%1}</value>
</trigger> |
Does that put that correct information into the window and into the variable? Can you use the #DEBUGFILE command to capture the data packets containing the data you want to parse? It would help me to clearly see the data that comes in and might allow me to test different triggers. |

I'm just getting the upside L in the window and assigned to parsedesc but I'm getting something that looks nicer in #DEBUGFILE
| Code: |
07/19/15 18:59:30:029 : <IAC><SB><69><1>SCROLL<2><LF><CR>
( )==========================================================================( )<LF><CR>
| |<LF><CR>
| |<LF><CR>
| - - - - |<LF><CR>
| |<LF><CR>
| |<LF><CR>

I'm guessing that the character you're seeing in the window is the ASCII control character <2>, and the reason you haven't been seeing the other lines is because . doesn't match newlines by default. Try this perhaps?
| Code: |
<trigger type="Telnet" param="69" priority="14520" regex="true" newline="false" prompt="true" enabled="false" id="506">
<pattern>(?s)SCROLL\x02(.*)</pattern>
<value>parsedesc=%1
#CLR scroll
#WINDOW scroll {%1}</value>
</trigger> |

That's exactly what I needed, Daern. Thank you. It's working perfectly now.
