Hi all,

i try to extract a steamid between 2 nodes.
But i recive a "No match found!"

Here the example:

Data String:

Date: Thu, 02 May 2012 14:18:38 GMT
         Server: Apache
         Vary: Accept-Encoding
         Content-Length: 230
         Connection: close
         Content-Type: text/xml
         
         <?xml version='1.0' standalone='yes'?><headtag>
           <test>STEAM_0:1:101010101</test>
           <b>NO</b>
           <c>YES</c>
           <d>FINE</d>
           <e>DATA</e>
         </headtag>

Code:

PHP Code:

#include <sourcemod>
#include <regex>

stock GetXMLNodeData(const String:XML[], String:buffer[], maxlen)
{
    static Handle:re = INVALID_HANDLE;
    if (re == INVALID_HANDLE)
        re = CompileRegex("/<test>(.+)<\\/test>/");
        
    if (MatchRegex(re, XML) > 1)
        GetRegexSubString(re, 1, buffer, maxlen);
    else
        strcopy(buffer, maxlen, "No match found!");
}

// ============

    // Stuf to get "xmldata"....

    decl String:info[256];
    GetXMLNodeData(xmldata, info, sizeof(info));
    LogToGame ("Debug: %s",xmldata);
    LogToGame ("-------------------------------------------");
    LogToGame ("Debug: %s",info); 


Any Ideas whats wrong?

Have a look at [EXTENSION] TinyXml Wrapper

Hi berni,

not possible with this extension to read directly from a string.

I do not want to write a xml file on the server first.
I need only the steamid from the string without an extension.

I think it works without files too:

PHP Code:

native TinyXml_Parse(Handle:doc, String:xmldata[]); 


I'm gonna test your code on my server ;)

[berni]

ehhh

MatchRegex returns:
Number of substrings found or -1 on failure.

you are checking for > 1 ? that would only be true if it exists more than one time.

The compiler probably also puked at the if statements without { } brackets

Edit: you seem to be right with checking > 1, however the regex pattern didn't work.
I tested a bit around and this is working for me:

PHP Code:

CompileRegex("<test>(.+)</test>"); 


MatchRegex then returned 2 (somehow) and buffer contains the desired value: "STEAM_0:1:101010101"

Thank you berni.

The "> 1" was the first issue. But after the fix my check returns every times a "0".

I get it after some test's and help from Impact123

Here the full function (works fine):

PHP Code:

stock GetXMLNodeData(const String:XML[], const String:node[], String:buffer[], maxlen)
{
   
    decl String:pattern[256];
    Format(pattern, sizeof(pattern), "(<%s>)([A-Za-z0-9:_]+)(</%s>)", node, node);
    static Handle:re = INVALID_HANDLE;
    if (re == INVALID_HANDLE)
    {
        re = CompileRegex(pattern);
    }

    if (MatchRegex(re, XML) >= 1)
        GetRegexSubString(re, 2, buffer, maxlen);
    else
        strcopy(buffer, maxlen, "No match found!");
}

//=============

    // data = XML String

    decl String:steamid[256];
    GetXMLNodeData(data, "test", steam, sizeof(steam)); 


Thank you all for your effort.
