Parsing File with C# And Replace method


Parsing File with C# And Replace method

I wish this helpful for you If your goal is to replace all instances of the ':' character where it is not followed by 2 or 3 other characters. You could indeed try the System.Text.RegularExpressions library. You could then simplify your cleanMessage function in the following way.
code :
using System.Text.RegularExpressions;

function string cleanMessage(string str)
{
     string pattern = ":(\s)"; //This will be a ':' followed by a space
     Regex rgx = new Regex(pattern);
     string replaceResult = rgx.Replace(str,"*$1") //this will replace the pattern with a '*' followed by a space. 
     return replaceResult;
}
using System.Text.RegularExpressions;

function string cleanMessage(string str)
{
     string pattern = "([^;]{2}.):(\s[^:]{2})"; 
     //This will be 2 characters that cannot be ':' followed by anything then a ':' followed by a space and 2 more characters that cannot by ':' 
     //For instance, "BNF: :F" would FAIL and not get replaced but "BNF: HH" would pass and become "BNF* HH"
     Regex rgx = new Regex(pattern);
     string replaceResult = rgx.Replace(str,"$1*$2") //this will replace the : with a * 
     return replaceResult;
}

I hope this helps . I want to take the current page's URL (using page:env("caller")) and extract a section of it. , 2 Ways to accomplish what you want.
1) In the pre block
code :
pre {
  queryInURL = page:url("query");
  q = queryInURL.replace(re/.*?q=(.*?)(?:$|&.*)/,"$1");
}
ruleset a60x439 {
  meta {
    name "url query test"
    description <<
      Getting the query from the current page URL
    >>
    author "Mike Grace"
    logging on
  }

  rule get_query {
    select when pageview ".*"
    pre {
      queryInURL = page:url("query");
      q = queryInURL.replace(re/.*?q=(.*?)(?:$|&.*)/,"$1");
    }
    {
      notify("Query",queryInURL) with sticky = true;
      notify("q",q) with sticky = true;
    }
  }

How to replace attribute name in an html file while parsing it with lxml?

I wish this help you use lxml with xslt to transform your html, like:
code :
from lxml import etree

h = '''<html>
  <head></head>
  <body>
    <p class ='person'><dfn>New-York</dfn></p>
    <p class = 'place'><dfn>John Doe</dfn></p>
  </body>
</html>'''
doc = etree.fromstring(h, etree.HTMLParser())

xsl = '''<xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:template match="node()|@*">
  <xsl:copy>
   <xsl:apply-templates select="node()|@*"/>
  </xsl:copy>
 </xsl:template>
 <xsl:template match="p">
    <xsl:variable name="original-class" select="string(@class)" />
    <xsl:copy>
        <xsl:apply-templates select="@*"/>
        <xsl:if test="dfn[text()='New-York']">
          <xsl:attribute name="class">
            <xsl:value-of select="concat('**', $original-class, '**')"/>
          </xsl:attribute>
        </xsl:if>
        <xsl:apply-templates select="node()"/>
    </xsl:copy>
   </xsl:template>
</xsl:stylesheet>'''
xslt_root = etree.XML(xsl)
transform = etree.XSLT(xslt_root)
result_tree = transform(doc)
print result_treeoutput:
$ python x.py 
<html>
<head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"></head>
  <body>
    <p class="**person**"><dfn>New-York</dfn></p>
    <p class="place"><dfn>John Doe</dfn></p>
  </body>
</html>
Java String replace method doesn't replace my '\' with '/' File Finder class

Java String replace method doesn't replace my '\' with '/' File Finder class

this one helps. You need to escape the slash. Currently you're escaping a single quote instead.
Change:
code :
fileName.replace('\'' , '/');
fileName = fileName.replace('\\' , '/');
Replace strings in a word document by parsing JSON file in C#

Replace strings in a word document by parsing JSON file in C#

help you fix your problem You replace the words in a loop, but you always use docText as the source. So when you want to replace the second animal, you again use docText where the first animal has not yet been replaced.
To solve that, you can set finalWordDocument = docText; before the foreach and always use finalWordDocument for the replacement:
code :
finalWordDocument = finalWordDocument.Replace(animals, humans);
Parsing a file with multiple line and replace the each first occurrence with Pipe

Parsing a file with multiple line and replace the each first occurrence with Pipe

To fix this issue Currently we have receiving a file, which is more like a name value pair. Each of the pair data is separated by pipe delimiter and Name and value pair is separated by space. I want to replace the space with Pipe inside the pipe delimited values. , This sed script creates the output as shown in the question.
code :
sed 's/\(|[^ ][^ ]*\) \([^|]\)/\1|\2/g' inputfile
