Using a variable in a Powershell search and replace string

Hi
a couple of days ago I posted a question about doing a search and replace with wildcards
Search and repalce with Widcards
I got a swift and very helpful answer but now I need to build on it.
In a text file I wanted to replace all the text between two defined words. the script I got was this
$text = 'Some Server this bit of text varies Language stuff'
$text -replace '(.*Server) .+? (Language.*)','$1 it will always say this $2'
It works great but now I want to replace "it will always say this" with a variable and I can't figure out the correct grammar to make this happen.
Can anyone help??
Thanks
Alex

Here's one way:
$replace = 'it will aways say this'if ( $text -match '(.*Server) .+? (Language.*)' )
{ "{0} $Replace {1}" -f $matches[1,2] }
else { $text }
[string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "

Search and replace string formatting

Hi,
I am trying to do a search and replace formatting of a string.
In the example I am looking for string "PASSED" but it must also start with usbflash and some number + PASSED.
I can't get the format to have a number from 1-99. The number of replacements should add up to 6 in this case. I have tried with \d for any number, and I also tried [1-99].
Solved!
Go to Solution.

Right click on the Search And Replace String function. There is an option to use Regular Expressions. Then give this a try.
EDIT: You will need to set the Replace All input to TRUE.

Search and Replace String throwing the wrong error message with regexp?

This came up in a LAVA thread, and I'm not sure if there's a bug here or not. When using Search and Replace string, and using a regular expression of [(G[b|i])], LabVIEW throws error -4622, "There is an unmatched parenthesis in a regular expression." There are obviously no unmatched parenthesis in that expression, so it seems to me that the wrong error is being thrown. I'm just not sure if that's a syntactically valid regexp. The problem seems to be with nesting [ ]'s inside ( )'s inside [ ]'s. I've tried a couple of regexp resources on the Web, and one suggests it's valid, while the other seems to think it isn't.

I think your regexp is invalid.
In regexps, brackets are not the same as parentheses. Parens are for grouping, while brackets are for matching one of a class of characters. Brackets can not be nested.
If the regexp is replaced with [G[bi]], there is no error, so it's not a matter of nested brackets. I couldn't find anything on the PCRE man page that forbids nested brackets specifically, but it makes sense.
Your expression "[(G[bi])]", therefore parses as a character class which matches '(', 'G', '[', 'b', or 'i' followed by an unmatched paren, and an unmatched bracket.
I don't believe that's the case. Replace the regexp with [(Gbi)], and the error goes away. So it's not a matter of the '(' being literal, and then encountering a ')' without a matching '('.
daveTW wrote:
what string exactly you want to replace? I think the round braces are not right in this case, since they mark partial matches which are given back by "match regular expression". But you don't want to extract parts of the string, you want to replace them (or delete, with empty <replace string>). So if you leave the outer [( ... )] then your RegEx means all strings with either "Gb" or "Gi".
It's not my regular expression. A poster at LAVA was having problems with one of his (a truly frightening one), and this seemed to be the element that was causing the problem. I'm pretty sure that the originator of the regexp meant to use G(b|i), which seems like a complicated way of matching "Gb" or "Gi", if you ask me.

Search and replace string function

Hello, I am using the "search and replace string" function and it does nt seem to work consistently for me. I am using it in a situation where I am taking an array of strings, converting this into a spreadsheet string then deleting all of the commas. Has anyone experienced the same behavior? I have searched through other posts and found other simular faults but none of the fixes worked for this. I can post the code it needed.
Thanks,
Andrew

I agree that commas are often not desirable, especially if your software should also work in countries where comma is used as a decimal seperator.
Where are the commas coming from? Does (1) each element of the original array have one (or more), do you (2) use comma as seperator if you convert it to a spreadhseet string?
For (1), you might just strip out the comma for each element right in the loop. For case (2) you would simply use a different separator to begin with, of course.
Btw: you are abusing a WHILE loop as a FOR loop, because you have a fixed number of iterations. Please replace it with a FOR loop. If you use a FOR loop, LabVIEW can manage memory much more efficiently, because it can allocate the entire output array before the loop starts. For While loops, the total number of iterations is not known to the compiler. (Of course a real program would also stop the loop if an error occurs. In this case you would need to stay woth the WHILE loop. )
Do you have a simple example how the raw array elements look like. How many commas are there?

Search and replace strings in a file while ignoring substrings

Hi:
I have a java program that searches and replaces strings in a file. It makes a new copy of the file, searches for a string in the copy, replaces the string and renames the new copy to the original file, thereafter deleting the copy.
Now searching for "abcd", for eg works fine, but searching for "Topabcd" and replacing it doesnot work because there is a match for "abcd" in a different search scenario. How can I modify the code such that if "abcd" is already searched and replaced then it should not be searched for again or rather search for "abcd" as entire string and not if its a substring of another string.
In the below code output, all instances of "abcd" and the ones of "Topabcd" are replaced by ABCDEFG and TopABCDEF respectively, whereas according to the desired output, "abcd" should be replaced by ABCDEFG and "Topabcd" should be replaced by REPLACEMEFIRST.
try
          String find_productstring = "abcd";
          String replacement_productstring = "ABCDEFG";
          compsXml = new FileReader(compsLoc);
          compsConfigFile = new BufferedReader(compsXml);
          File compsFile =new File("file.xml");

        catch (IOException e)
        //since "Topabcd" contains "abcd", which is the search above and hence the string "Topabcd" is not replaced correctly

How to get numeric result from 'search and replace' string function

Your problem is the fact that you are converting it to an integer, thus loosing the fractional part. You need to use "Fract/Exp String To Number" instead and create a DBL so yor data is 23.3 instead of 23.
You also don't need to manipulate the string if the initial part is of constant lenght. Just use the offset input as in the figure below.

Please fill all your controls with typical strings, make the new values the default, save the VI under a new name, and attach it again.
(This allows us to quickly reproduce your problem without entering strings and having to guess what your inputs actually are)
WIth your given string, the result seems as expected, so we need more information on what you actually want instead.

Search and replace string inside a column

Hi,
in my table there is Column A with Type NVARCHAR.
i need to search inside all the rows in that column to find the string "_TH" and remove it wherever it exist.
how can i do it?

you can follow below solution .
Step 1: Create a temporary table to load all the records which are having column with '-TH'
Step 2 : Use update statement and join it with temporary table to update the qualified records
Benefits: This is a set based solution which is optimal and high perfroming
Script:
create table test1(col1 nvarchar(20))
insert into test1 values('one_th'),('two_th'),('Gauri')
--Create Temporary table
select *
into #tmp2
from Test1
where col1 like '%_TH%'
--update all such rows which are having column with '_TH'
Note: I am replacing all columns with '_TH' with space . you can replace with other characters based upon your requirement.
update t
set col1 = replace(t.col1,'_TH','')
from test1 t
inner join #tmp2 t2
on t.col1 = t2.col1
Please comment If this solution helps you.

Xml search and replace for 'Session Variables' in column title view

Hi Experts,
I have around 10 reports where measure column titles are displayed based the session variable.
Below is the syntax I have used in the column title
@{biServer.variables['NQ_SESSION.VariableName']}
Now I would like to replace the above syntax with some static text. To do this, I am trying to use the xml search and replace feature in the catalog manager.
For some reason, catalog manager is unable to find the syntax in the xml file. I have tried using escape character also for the apostrophe by using &apos, but no luck.
Any pointers on how to replace the text?
Thanks

Using Analysis get the xml conversion for @{biServer.variables['NQ_SESSION.VariableName']} from Advanced tab's xml code
use this code to find in catalog manager, if you able to find then go for search and replace option.
I think this should work for you.

Case insensitive search and replace using ASP and Oracle database

I am interested in providing a case insensitive search and replace query in a Active server page. At present data is collected from a html form which passes the text values to a ASP page. The ASP page runs a search (select query) to find if the data is already in the Oracle database, if it isn't the ASP page runs sql (INSERT) to insert the record, if not the page returns a form indicating that the record already exists. At present we can convert the case of new records using the VB UCase() function. But can't do a insensitive search with the existing records. *The Query must be able to utilize ASP variables.
Any help would be much appreciated.

public class BasicXMLReplaceWithDOM4J {
     static String inputFile = "C:/student.xml";
     static String outputFile = "C:/studentRenamed.xml";
     public static void main(String[] args) throws Exception {

          Document doc = DocumentBuilderFactory.newInstance()
                    .newDocumentBuilder().parse(new InputSource(inputFile));
          // Use XPath to find all nodes where student is named 'Suresh'
          XPath xpath = XPathFactory.newInstance().newXPath();
          NodeList nodes = (NodeList)xpath
               .evaluate("//stud_name[text()='Suresh']", doc, XPathConstants.NODESET);
          // Rename these nodes
          for (int idx = 0; idx < nodes.getLength(); idx++) {
               nodes.item(idx).setTextContent("Suresh-Renamed");

GUI Based tool for search and replace using regular expression

Hi,
I have developed this small tool which can be used for search and replace in multiple files using reqular expressions.
Features:
1. Full regular expression
2. GUI based with Highlighted results
3. Preview for replace available
4. Pure Java based.
5. Its like unix sed and grep
Please visit below site for download/more information :
http://sourceforge.net/projects/regexsearchrepl/
Thanks,
Hitesh Viseria

I agree with you, it cannot compete grep/sed/awk combination. I couldnt find anything even close to grep/sed for windows which will also have a preview and most important, free. That is what made me write this tool. I am trying to
improve its performance and more features like history etc.
Any suggestions on additional features are most welcome.
