I've been trying every combination to make this if then statement work on my ASP page. I've calling fields from 2 access database, then I need to compare both to see if there is a facility that has a report against them.
At first I was using the facility name as the anchor to both database files. It worked pretty good until there was an issue with double quotes in the name. This code worked
<%
for k=0 to y-1
if (B(1,k)) = facility then
%>•<%=B(2,k)%><br /><%
end if
NEXT
%>
So all I did was add a facility id number in the second database (row 12) since the ID already existed in the first database
<%
for k=0 to y-1
response.write(ID)
response.write("\")
response.write(B(12,k))
if (B(12,k)) = ID then
response.write("TRUE")
%>•<%=B(2,k)%><br /><%
else
response.write("FALSE")
end if
response.write("<br>")
NEXT
%>
as you can see, I've tested that the values are acually the same. The results of this If Then is;
2006225\2006225FALSE 2006225\2007101FALSE 2006225\2006225FALSE
2006225\2004245FALSE 2006225\279025FALSE 2006225\2006225FALSE
2006225\2006225FALSE 2006225\2006225FALSE 2006225\2006225FALSE
Since your example code does not show how your variable named ID is assigned, my first guess would be that this may be due to variables being untyped in VBscript and you may not be assigning the type you are expecting to either the above mentioned variable or your array in the above code. You may want to use forced concatenation to make certain the evaluation is based on string types. You can concatenate an empty string in VBscript to force it to evaluate the whole expression as a string (this is what is also happening when you are writing the output). If it works this way, then most likely your variable may actually be getting assigned to a recordset field rather than a string value or something similar.
if ("" & B(12,k)) = ("" & ID) then

I’m trying to obtain the count of all title containing a specific string from a dictionary in a jinja template.
I have tried many variant with select and other test and haven’t found the right way to do so.
This is not for ansible for which I have found many solutions to fix this issue.
Also the test equalto does not work since I do not have an exact match on the string and doesn’t seem to take regex.
{{ Dictionnary | selectattr("title", "in","MyString") | list | count }}
It seems that the string never gets properly evaluated because it always returns 0.
The selectattr without test return the right number of total titles.
I wonder if we could evaluate it with an if statement somehow.
I'm brand new to using PBI but as far as I can tell, I should be able to substitute a parameter as part of a Direct Query in place of a hard-coded variable...ie
let
Source = Sql.Database("NAMEOFDB", "CMUtility", [Query="sp_get_residentsinfo "& home_name]),.....
instead of
let
Source = Sql.Database("NAMEOFDB", "CMUtility", [Query="sp_get_residentsinfo 'NAME OF HOME'"]),...
However, the parameter-included version just says
DataSource.Error: Microsoft SQL: Incorrect syntax near 'House'.
Details:
DataSourceKind=SQL
DataSourcePath=NAMEOFDB;CMUtility
Message=Incorrect syntax near 'House'.
Number=102
Class=15
"House" is the currently - assigned last word of the home_name variable. What have I done wrong?
PS - I have surmised that I shouldn't need the extra & at the end of the parameter, as I'm not adding anything else to the query, but even with both &s it still doesn't work.
The type of your parameters is text. In SQL, text literals must be quoted, i.e. sp_get_residentsinfo 'NAME OF HOME', but the statement build by you is sp_get_residentsinfo NAME OF HOME.
You should use Text.Replace to escape single quotes in the parameter's value and append a quote before and after it.
I have code that currently looks like this:
replace fname = "JACK" if id==103
replace lname = "MARTIN" if id==103
replace fname = "MICHAEL" if id==104
replace lname = "JOHNSON" if id==104
And it goes on for multiple pages like this, replacing an ID name with a first and last name string. I was wondering if there is a more efficient way to do this en masse, perhaps by using the recode command?
I will echo the other answers that suggest a merge is the best way to do this.
But if you absolutely must code the lines item-wise (again, messy) you can generate a long list ("pages") of replace commands by using MS Excel to "help" you write the code. Here is a picture of your Excel sheet with one example, showing the MS Excel formula:
columns:
A B C D
row: 1 last first id code
2 MARTIN JACK 103 ="replace fname=^"&B2&"^ if id=="&C2
You type that in, make sure it looks like Stata code when the formula calculates (aside from the carets), and copy the formula in column D down to the end of your list. Then copy the whole block of Stata code in column D generated by the formulas into your do-file, and do a find and replace (be careful here if you are using the caret elsewhere for mathematical uses!!) for all ^ to be replaced with ", which will end up generating proper Stata syntax.
(This is truly a brute force way of doing this, and is less dynamic in the case that there are subsequent changes to your generation list. All--apologies in advance for answering a question here advocating use of Excel :) )
You don't explain where the strings you want to add come from, but what is generally the best technique is explained at
http://www.stata.com/support/faqs/data-management/group-characteristics-for-subsets/index.html
Create an associative array of ids vs Fname,Lname
103 => JACK,MARTIN
104 => MICHAEL,JOHNSON
...
Replace
id => hash{id} ( fname & lname )
The efficiency of doing this will be taken care by the programming language used
I am developing an application using Qt/KDE. While writing code for this, I need to read a QString that contains values like ( ; delimited)
<http://example.com/example.ext.torrent>; rel=describedby; type="application/x-bittorrent"; name="differentname.ext"
I need to read every attribute like rel, type and name into a different QString. The apporach I have taken so far is something like this
if (line.contains("describedby")) {
m_reltype = "describedby" ;
}
if (line.contains("duplicate")) {
m_reltype = "duplicate";
}
That is if I need to be bothered only by the presence of an attribute (and not its value) I am manually looking for the text and setting if the attribute is present. This approach however fails for attributes like "type" and name whose actual values need to be stored in a QString. Although I know this can be done by splitting the entire string at the delimiter ; and then searching for the attribute or its value, I wanted to know is there a cleaner and a more efficient way of doing it.
As I understand, the data is not always an URL.
So,
1: Split the string
2: For each substring, separate the identifier from the value:
id = str.mid(0,str.indexOf("="));
value = str.mid(str.indexOf("=")+1);
You can also use a RegExp:
regexp = "^([a-z]+)\s*=\s*(.*)$";
id = \1 of the regexp;
value = \2 of the regexp;
I need to read every attribute like rel, type and name into a different QString.
Is there a gurantee that this string will always be a URL?
I wanted to know is there a cleaner and a more efficient way of doing it.
Don't reinvent the wheel! You can use QURL::queryItems which would parse these query variables and return a map of name-value pairs.
However, make sure that your string is a well-formed URL (so that QURL does not reject it).
I've stumbled on a bit of challenge here: how to get the contents of a table in HTML with the help of a regular expression. Let's say this is our table:
<table someprop=2 id="the_table" otherprop="val">
<tr>
<td>First row, first cell</td>
<td>Second cell</td>
</tr>
<tr>
<td>Second row</td>
<td>...</td>
</tr>
<tr>
<td>Another row, first cell</td>
<td>Last cell</td>
</tr>
</table>
I already found a method that works, but involves multiple regular expression to be executed in steps:
Get the right table and put it's rows in back-reference 1 (there may be more than one in the document):
<table[^>]*?id="the_table"[^>]*?>(.*?)</table>
Get the rows of the table and put the cells in back-reference 1:
<tr.*?>(.*?)</tr>
And lastly fetch the cell contents in back-reference 1:
<td.*?>(.*?)</td>
Now this is all good, but it would be infinitely more awesome to do this all using one fancy regular expression... Does someone know if this is possible?
There really isn’t a possible regex solution that works for an arbitrary number of table data and puts each cell into a separate back reference. That’s because with backreferences, you need to have a distinct open paren for each backref you want to create, and you don’t know how many cells you have.
There’s nothing wrong with using looping of one or another sort to pull out the data. For example, on the last one, in Perl it would be this, given that $tr already contains the row you need:
#td = ( $tr =~ m{<td.*?>(.*?)</td>}sg );
Now $td[0] will contain the first <td>, $td[1] will contain the second one, etc. If you wanted a two-dimensional array, you might wrap that in a loop like this to populate a new #cells variable:
our $table; # assume has full table in it
my #cells;
while(my($tr) =~ $table = m{<tr.*?>(.*?)</tr>}sg) {
push #cells, [ $tr =~ m{<td.*?>(.*?)</td>}sg ];
}
Now you can do two-dimensional addressing, allowing for $cells[0][0], etc. The outer explicit loop processes the table a row at a time, and the inner implicit loop pulls out all the cells.
That will work on the canned sample data you showed. If that’s good enough for you, then great. Use it and move on.
What Could Ever Be Wrong With That?
However, there are actually quite a few assumptions in your patterns about the contents of your data, ones I don’t know that you’re aware of. For one thing, notice how I’ve used /s so that it doesn’t get stuck on newlines.
But the main problem is that minimal matches aren’t always quite what you want here. At least, not in the general case. Sometimes they aren’t as minimal as you think, matching more than you want, and sometimes they just don’t match enough.
For example, a pattern like <i>(.*?)</i> will get more than you want if the string is:
<i>foo<i>bar</i>ness</i>
Because you will end up matching the string <i>foo<i>bar</i>.
The other common problem (and not counting the uncommon ones) is that a pattern like <tag.*?> may match too little, such as with
<img alt=">more" src="somewhere">
Now if you use a simplistic <img.*?> on that, you would only capture <img alt=">, which is of course wrong.
I think the last major remaining problem is that you have to altogether ignore certain things in parsing. The simplest demo of this embedded comments (also <script>, <style>, andCDATA`), since you could have something like
<i> some <!-- secret</i> --> stuff </i>
which will throw off something like <i>(.*?)</i>.
There are ways around all these, of course. Once you’ve done so, and it is really quite a bit of effort, you’ll find that you have built yourself a real parser, completely with a lot of auxiliary logic, not just one pattern.
Even then you are only processing well-formed input strings. Error recovery and failing softly is an entirely different art.
This answer was added before it was known the the OP needed a solution for c++...
Since using regex to parse html is technically wrong, I'll offer a better solution. You could use js to get the data and put it into a two dimensional array. I use jQuery in the example.
var data = [];
$('table tr').each(function(i, n){
var $tr = $(n);
data[i] = [];
$tr.find('td').text(function(j, text){
data[i].push(text);
});
});
jsfiddle of the example: http://jsfiddle.net/gislikonrad/twzM7/
EDIT
If you want a plain javascript way of doing this (not using jQuery), then this might be more for you:
var data = [];
var rows = document.getElementById('the_table').getElementsByTagName('tr');
for(var i = 0; i < rows.length; i++){
var d = rows[i].getElementsByTagName('td');
data[i] = [];
for(var j = 0; j < d.length; j++){
data[i].push(d[j].innerText);
}
}
Both these functions return the data the same way.
