Dataviewjs by file name

What I’m trying to do

I have hundreds of notes in my zettelkasten like the titles below:

  • C20.S01.I01
  • C20.S01.I02
  • C20.S01.I03
  • C20.S01.I04
  • C20.S02.I05
  • C20.S02.I06
  • C20.S03.I07
  • C20.S04.I08
    (…)
    I use this code to bring up all the contents:
```dataviewjs 
//Configurations
const pages = dv.pages('#C20').sort(p => p.file.name, "asc");// Make your search
const headName = "";

for (const page of pages) {
    const content = await dv.io.load(page.file.path);
    const lines = content.split('\n');
    var output = [];
    var insideHead = false;
	
        // Displaying the file name
	dv.header(3, page.file.name);
    
    for (const line of lines) {
        if (line.startsWith("# " + headName)) {
            insideHead = true;
        } else if (line.startsWith("# ") && insideHead) {
            insideHead = false;
            break;  // Exit the loop when the next heading is encountered
        } else if (insideHead) {
            output.push(line);
        }
    }
    dv.paragraph(output.join('\n'));
}

But, if I only want the notes that filename start with “C20.S01.”, without bringing the rest, how do I do that?

Thankyou everybody

something like:

const pages = dv.pages(‘#C20’).where(p => p.file.name.startsWith(“C20.S01”).sort(p => p.file.name, “asc”);
