Parse a line in XML format

joma

When I try to parse a line in a file in XML format I get an error:

E- *Error* parseString: argument #1 should be either a string or a symbol (type template = "SS") - ("global_min_aper")

The code I am using is:

axlExportXmlDBRecords("./temp_params.txt" nil)
    minWidth_port = infile("./temp_params.txt")
        when( minWidth_port
            while( param_line = gets(param_line minWidth_port)
                    if(rexMatchp("smooth_min_gap" param_line) then
                    println(list("Global aper raw value = " param_line ))
                global_min_aper = nth( 1 parseString(global_min_aper "<>"))
                    println(list("Global aper parsed value = " param_line ))
                        );if
                    );while
            );when
    close( minWidth_port )

This is basically a copy of the code which works for me on a typical report text file .
Can anyone point out what I am missing here?
Thanks.

  • below is what I think is the corrected version of your code:

            axlExportXmlDBRecords("./temp_params.txt" nil)
            minWidth_port = infile("./temp_params.txt")
            when( minWidth_port
                while( param_line = gets(param_line minWidth_port)
                    if(rexMatchp("smooth_min_gap" param_line) then
                        println(list("Global aper raw value = " param_line ))
                        (global_min_aper = nth( 2 parseString(param_line  "<>")))
                        println(list("Global aper parsed value = " global_min_aper ))
                    );if
                );while
            );when
            close( minWidth_port )

  • Thanks David, it seems that an extra pair of brackets is the solution here to stop the error message.
    I have not seen this before. Could you explain in which cases it is neccessary to do this or why?
    For example in the same program I have the code:

    minWidth_port = infile("./eld_rep.rpt")
                when( minWidth_port
                    while( eld_line=gets(eld_line minWidth_port)
                        if(i<5
                        then
                        i++
                            else
                                lineList = parseString(eld_line ",")

    which gives no error and I have others that use nth in conjuction with parseString that work ok.

  • I think the error was caused by parsing the variable 'global_min_aper' which has no value,

    I changed the code to parse the 'param_line' variable containing the string from the open file
