Answer 1

You can use HtmlAgilityPack for parsing Html like below. I didn't test this, you can give it a try.

$html = @"
<div class="kitchen">
   <div class="kitchen">
        <blockquote>kitchen<br />
            <span class="kitchen">kitchen</span>
        </blockquote>
        <a href='test'><img title="kitchen" src="https://kitchen-sink.local" /></a>
    </div>
</div>
"@

$htmlDocument = New-Object -TypeName HtmlAgilityPack.HtmlDocument
$htmlDocument.LoadHtml($html)
foreach($x in $htmlDocument.DocumentNode.Descendants()) {
    if($x.Name -eq "//a[@href]") {
        //your logic here
    }
}

You can achieve it using RegEx as well- First, you need to get the item, and then from the item, you need to get the field value. here below example will work fine for a single item but if you need it for multiple items you need to perform a loop, for example, getting children of a root item.

$anchorTagPattern = '(?is)<a[^>]*>(.*?)<\/a>';

$hrefPattern = '(?is)href=\"[^>]*(.*?)\"';

#get item by item id i.e {BB87FEE6-E4CF-4D86-986B-2D1B297A081F}
$item = Get-Item -Path "master:" -ID "{BB87FEE6-E4CF-4D86-986B-2D1B297A081F}"

#get field value by field name i.e Content
$htmlContent = $item.Fields["Content"].Value;

$anchorTagPatternMatches = [regex]::Matches($htmlContent, 
$anchorTagPattern);

if(![string]::IsNullOrEmpty($anchorTagPatternMatches)) {
    
    $anchorTagPatternMatches | ForEach-Object {
        $anchorText = $_.Groups[1].Value;
        $anchorTag = $_[0].Value;
        write-host $anchorTag
        write-host $anchorText
    if(![string]::IsNullOrEmpty($anchorTag)){   
        $hrefPatternMatches = [regex]::Matches($anchorTag, $hrefPattern);
        $href = $hrefPatternMatches[0].Value;
        $href = $href.Replace('href=','');
        write-host $href
        }
    }
    
}

For the Rich Text Editor field, you can use this PowerShell script and get all the links.

# Get your item here by providing ID
$rootItem = Get-Item -Path "master:" -ID "{56305117-8C9C-4C08-96D5-BB97A8E27419}"

# Regex pattern to check if the value contains any anchor
$anchorTagPattern = '(?is)<a[^>]*>(.*?)<\/a>';

# Get your RTE Field 
$richTextContent = $rootItem.Fields["DB"].Value;

# Match parttern with your RTE field value
$anchorTagPatternMatches = [regex]::Matches($richTextContent, $anchorTagPattern);

# If Pattern matches 
if(![string]::IsNullOrEmpty($anchorTagPatternMatches)) {

# Create a loop and it will give you all the anchors in your RTE
ForEach ($patterns in $anchorTagPatternMatches) {
       # You will get the values of anchors using this. 
       Write-Host $patterns
    
    }
}

The output you will get is this.

<a href="http://test.com">newLink</a>
<a href="http://google.com">newLink</a>
<a href="http://google.com">Google</a>

And you can get other values as well.

For any other field, you can pass your field name like below and get the details of the links.

$richTextContent = $rootItem.Fields["your field"].Value;

How to update the anchor link text in rich text field using Sitecore Powershell?

Answer 4

You can get the link detail on the page by using the code below :-

$pages = get-item -Path "<item path>"
$getPageLinks = $page.Fields | where {$_.Type -eq 'General Link'}
            ForEach ($link in $getPageLinks) 
            {  
              [Sitecore.Data.Fields.LinkField] $field = $link
              if(-not [string]::IsNullOrEmpty($field))
                {
                        <your code>
                }
            }

Related to get the link details of the components on the page, you need to get the rendering of the page first and based on it you can get the links. I am sharing the example of richtext editor here.

$renderings = Get-Rendering -Item $page -Device $device -FinalLayout 
    foreach($rendering in $renderings){
    
        if($rendering.ItemID -ne $null -and $rendering.Datasource -ne "")
        {
            $renderingItem = Get-Item master: -ID $rendering.ItemID  -ErrorAction Ignore
            if($renderingItem -ne $null) {
                $renderingDataItemPath = "master:" + $rendering.Datasource
                $renderingDataItem= Get-Item -Path $renderingDataItemPath -ErrorAction Ignore
                $getRichTextDetail=$renderingDataItem.Fields | where {$_.Type -eq 'Rich Text'}
                               
                                if(-not [string]::IsNullOrEmpty($getRichTextDetail.Value))
                                {
                                    $fieldValueWithHtml = $getRichTextDetail.Value
                                    if($fieldValueWithHtml -ne $null){
                                        $source = [System.Web.HttpUtility]::HtmlDecode($fieldValueWithHtml)
                                        $html = New-Object -ComObject "HTMLFile";
                                        $html.IHTMLDocument2_write($source); # Reading in to a proper HTML document
                                        $html.Links | % {
                                         if(-not [string]::IsNullOrEmpty($_.href))
                                             {
                                                <your logic here>
                                             }
                                        }
                                    }
                                }
                }
        }
}

Hope this helps!!
