I made a ans ASP on wich a user can enter a number, one or more characters, and a word. Then he can press the button and it replaces in the given characters in the word with the given numbers.
My question is how can I let the script replace single characters when the user entered more?
i.e. Entry is "ab" the word is "abby", and the number is "1", my current program makes "1by", but I want to make it "111y", how do I realize that?

The Replace function replaces the search string (l_letter) in the given expression (here l_wort) with the replacement string (l_zahl). To replace all characters in l_letter with l_zahl you need to do the replacement in a loop for each character in l_letter. However, the Split function doesn't allow you to split a string into an array of its characters. It splits a string at a given delimiter character (space by default). Calling Split on a variable without a space will give you an array with just a single field containing the original string. Also, VBScript doesn't expand variables in strings, so if you put variable in double quotes you'll get the literal string "variable", not a string with the value of the variable.
var = "ab" : Split("var") ⇒ [ "var" ]
var = "ab" : Split(var) ⇒ [ "ab" ]
var = "a b" : Split(var) ⇒ [ "a", "b" ]
For extracting individual characters from a string use the Mid function:
l_replace = l_wort
For i=1 To Len(l_letter)
l_replace = Replace(l_replace, Mid(l_letter, i, 1), l_zahl)
Next
A better approach than doing multiple replacements in a loop would be using a regular expression replacement:
Set re = New RegExp
re.Pattern = "[" & l_letter & "]"
l_replace = re.Replace(l_wort, l_zahl)
Treat the character input as a list/collection of letters to replace:
Option Explicit
Dim f : f = "ab"
Dim t : t = "1"
Dim w : w = "abby"
WScript.Echo f, t, w
Dim i
For i = 1 To Len(f)
w = Replace(w, Mid(f, i, 1), t)
Next
WScript.Echo f, t, w
output:
cscript 47469843.vbs
ab 1 abby
ab 1 111y

Here is the string I want to match 76c24efd-ec42-492a-92df-c62cfd4540a3. The following regex will match a 36 char length string with alphanumeric characters and '-'.
[a-zA-Z0-9\-]{36}
I am trying to add to this regex, so it matches only when <8 chars> - <4 chars> - <4 chars> - <4 chars> - <12 chars>
The following will match a group of 8 characters followed by a dash, then a group of 4 characters followed by a dash 3 times, and then a group of 12 characters.
^[a-z0-9]{8}-(?:[a-z0-9]{4}-){3}[a-z0-9]{12}$/
Here's a short JavaScript test that shows the results.
$('.test').each(function(row, item) {
var val = $($(item).children()[0]).html()
var result = /^[a-z0-9]{8}-(?:[a-z0-9]{4}-){3}[a-z0-9]{12}$/gi.test(val);
$($(item).children()[1]).html(result.toString())

Dim dd As String
dd = IE.Document.getElementsByClassName("Temperatura średnia")(0).innerText
MsgBox dd
' Show IE
IE.Visible = True
' Clean up
Set IE = Nothing
Application.StatusBar = ""
End Sub
Without any result (the code does nothing). I will appreciate any help.
Here is the example using XHR and RegEx to retrieve all table data from the webpage:
Option Explicit

.Send
sContent = .ResponseText
End With
' parse with regex
With CreateObject("VBScript.RegExp")
.Global = True
.MultiLine = True
.IgnoreCase = True
' minor html simplification
.Pattern = "<span[^>]*>|</span>|[\r\n\t]*"
sContent = .Replace(sContent, "")
' match each table row
.Pattern = "<tr><td class=""indent"">(.*?)</td><td>(.*?)</td><td>(.*?)</td><td>(.*?)</td></tr>"
With .Execute(sContent)
ReDim aResult(1 To .Count, 1 To 4)
' each row
For i = 1 To .Count
With .Item(i - 1)
' each cell

.Columns.AutoFit
End With
End With

The output is as follows for me:
To extract the mean temperature only you can get the value from the first match having 0 index, since the mean temperature is in the first row of the table:

.MultiLine = True
.IgnoreCase = True
' minor html simplification
.Pattern = "<span[^>]*>|</span>|[\r\n\t]*"
sContent = .Replace(sContent, "")
' match each table row
.Pattern = "<tr><td class=""indent"">.*?</td><td>(.*?)</td><td>.*?</td><td>.*?</td></tr>"
With .Execute(sContent)
If .Count = 15 Then
' get the first row value only
MsgBox DecodeHTMLEntities(.Item(0).SubMatches(0))
Else
MsgBox "Data structure inconsistence detected"
End If
End With
End With
End Sub
Function DecodeHTMLEntities(sText As String) As String
Static oHtmlfile As Object
Static oDiv As Object
If oHtmlfile Is Nothing Then
Set oHtmlfile = CreateObject("htmlfile")
oHtmlfile.Open
Set oDiv = oHtmlfile.createElement("div")
End If
oDiv.innerHTML = sText
DecodeHTMLEntities = oDiv.innerText
End Function
Note, such methods will work until the webpage structure is changed.
I'm trying to scrap a website I'm a newbie using regular expressions. I have a long character vector, this is the line that I'm aiming:
<h3 class=\"title4\">Results: <span id=\"hitCount.top\">10,079</span></h3>\n
I want to extract the number that it is in between <span id=\"hitCount.top\"> and </span>. In this case 10,079. My approach so far, though, not really working.
x <- '<h3 class=\"title4\">Results: <span id=\"hitCount.top\">10,079</span>'
m <- gregexpr(pattern="[<span id=\"hitCount.top\">].+[</span>]", x, ignore.case = FALSE, perl = FALSE,
fixed = FALSE, useBytes = FALSE)
regmatches(x, m)
Any help will be appreciated.
Just to illustrate how easy it may become if you are using XML package:
> library("XML")
> url = "PATH_TO_HTML"
> parsed_doc = htmlParse(file=url, useInternalNodes = TRUE)
> h3title4 <- getNodeSet(doc = parsed_doc, path = "//h3[#class='title4']")
> plain_text <- sapply(h3title4, xmlValue)
> plain_text
[1] "Results: 10,079"
> sub("\\D*", "", plain_text)
[1] "10,079"
The sub("\\D*", "", plain_text) line will remove the first chunk of 0+ non-digits in the input, that is, \D* will match Results: and will replace it with an empty string.
The example HTML I used was
<html>
<body>
<h3 class="title4">Results: <span id="hitCount.top">10,079</span></h3>
<img width="10%" height="10%" src="https://upload.wikimedia.org/wikipedia/commons/thumb/f/fe/Green-Up-Arrow.svg/2000px-Green-Up-Arrow.svg.png"/>
</body>
</html>
Using stringr library
> library(stringr)
> str_extract(x, "(?<=<span id=\"hitCount.top\">)(.*?)(?=</span>)")
[1] "10,079"
Using gsub (sub can also be used here instead of gsub)
> gsub(".*<span id=\"hitCount.top\">(.*?)</span>.*", "\\1", x)
[1] "10,079"
I need to validade date yyyy-mm-dd on user keyup.
I'm currently at validating yyyy-mm with this Regex
^\d{0,4}$|^\d{4}[-]$|^\d{4}[-](0?[0-9]|1[012])$
JS Fiddle
But I need validade others part of date. Can anyone help me?
Explanation: Vague checking input while typing if it matches the desired format yyyy-mm-dd.
Modified your current regex a bit and added the dd part so it becomes
^\d{0,4}$|^\d{4}-0?$|^\d{4}-(?:0?[1-9]|1[012])(?:-(?:0?[1-9]?|[12]\d|3[01])?)?$
(?: opens a non capture group for alternation
0?[1-9]? optional 1-9 with preceding 0 or zero
[12]\d days 10-29
3[01] days 30 and 31
See the demo at regex101
For dd-mm-yyyy try this variant:
^0?$|^(?:0?[1-9]|[12]\d|3[01])(?:-(?:(?:0$|0?[1-9]|1[012]?)(?:-\d{0,4})?)?)?$
Or for mm-dd-yyyy that one:
^0?$|^(?:0?[1-9]|1[012]?)(?:-(?:(?:0$|0?[1-9]|[12]\d|3[01])(?:-\d{0,4})?)?)?$
This does not actually validate a date (leap years/28-31 days). Just loose checks input while typing, you can probably make it shorter. As follows an example with the yyyy-mm-dd pattern.
$("#date").on("keyup", function()
{
let valid = /^\d{0,4}$|^\d{4}-0?$|^\d{4}-(?:0?[1-9]|1[012])(?:-(?:0?[1-9]?|[12]\d|3[01])?)?$/.test(this.value), input = this.value;
if(!valid) {
this.value = input.substring(0, input.length - 1);
this.style.backgroundColor = '#EEA39C';
}
setTimeout(() => { this.style.backgroundColor = '#88DD85'; }, 700);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input id="date" style="font-size: 20px" maxlength="10" type="text" />
To validate the full date when typed/submitted see this answer of #PhiLho and rearrange it to the desired format, e.g. for yyyy-mm-dd
function isValidDate(date)
{
var matches = /^(\d{4})-(\d{1,2})-(\d{1,2})$/.exec(date);
if (matches == null) return false;
var y = matches[1];
var m = matches[2] - 1;
var d = matches[3];
var composedDate = new Date(y, m, d);
return composedDate.getDate() == d &&
composedDate.getMonth() == m &&
composedDate.getFullYear() == y;
}
<input type="text" id="date" style="font-size: 17px" value="2016-03-16">
<button onclick="alert(
isValidDate(getElementById('date').value)
);" style="font-size: 17px">check date</button>
This regex is a bit complex, but check the whole Gregorian rule.
regExp = "(((\d{2}(([13579][26])|([2468][480])|(0[48])))|(([13579][26])|([02468][480]))00)-02-29)|(\d{4}-((?:(0[13578]|1[02])-([0-2]\d|3[0-1]))|(?:(0[469]|11)-([0-2]\d|30))|(?:02-([0-1]\d|2[0-8]))))"
var regExp = /^(\d{4})-(\d{2})-(\d{2})$/
regExp.test(value);

After some fiddling I have derived a regex/VBA solution using
XMLHTTP to access the site (change strSite to suit)
a Regexp to get the required numbers
a variant array with 20 records to hold, then dump the numbers to the active sheet
Looking at the source HTML to find Regex patterns
The Call options have a common starting and finishing string that delimit the 10 values, but there are three different strings
Strings 1-4,7-10 for each record match <td class="ylwbg">X</td>
String 6 has a Style (and other text) preceding the > before the X
String 5 contains a much longer <a href textX</a>
A regex of
.Pattern = "(<tdclass=""ylwbg"")(Style.+?){0,1}>(.+?)(<\/td>)"
extracts all the needed strings, but further work is needed later on string 5
The Put options start with <td class="nobg" so these are happily not extracted by a regex that gets points 1-3
