Yash-777 opened a new pull request #395: Replaces the given String, with the
String which is nested in between two Strings.
URL: https://github.com/apache/commons-lang/pull/395
Replace String with the String which is nested in between two Strings.
I have used this Method in order to generate dynamic HTML reports to send a
mail.
```java
public class Test {
public static void main(String[] args) throws Exception {
String data = new
String(Files.readAllBytes(Paths.get("./dynamicReport.html")));
String rowSaperator = "";
String rowDataSaperator = "[~$List$~]";
List dynamicRecords = new ArrayList<>();
dynamicRecords.add( new String[]{ "1", "1" } );
dynamicRecords.add( new String[]{ "1", "1" } );
dynamicRecords.add( new String[]{ "2", "1" } );
dynamicRecords.add( new String[]{ "1", "2" } );
String finalTableData = dynamicRecordData(data, rowSaperator,
rowDataSaperator, dynamicRecords);
String targetFilePath = "D:/dynamicReport.txt";
try (PrintWriter out = new PrintWriter( targetFilePath )) {
out.println( finalTableData );
}
}
public static String dynamicRecordData(String str, String rowSaperator,
String rowDataSaperator, List dynamicRecords) throws Exception {
if( str.length() <= ( (rowSaperator.length())*2 +
rowDataSaperator.length()) ) {
return str;
}
String substringBetween = StringUtils.substringBetween(str,
rowSaperator, rowSaperator);
if( substringBetween == null) {
return str;
}
int countMatches = StringUtils.countMatches(substringBetween,
rowDataSaperator);
if( str.length() <= ( (rowSaperator.length())*2 +
(rowDataSaperator.length())*countMatches ) ) {
return str;
}
StringBuffer dynamicRowData = new StringBuffer();
String[] searchList = null;
for (String[] dynamicRecord : dynamicRecords) {
if( dynamicRecord.length == countMatches ) {
if( searchList == null ) {
searchList = new String[countMatches];
for (int i = 0; i < countMatches; i++) {
searchList[i] = rowDataSaperator;
}
}
String replaceEach =
StringUtils.replaceEach(substringBetween, searchList, dynamicRecord);
dynamicRowData.append(replaceEach);
} else {
throw new Exception("Records mismatch.");
}
}
String finalTableData = StringUtils.replaceSubstringInBetween(str,
dynamicRowData.toString(), rowSaperator, rowSaperator);
return finalTableData;
}
}
```
Sample HTML Template. Where i my case there are to many dynamic tables with
provided list data to replace.
```html
Header1Header2
[~$List$~][~$List$~]
```
After code generated report.
