PowerShell - Copy strings from some html tags to another html tags

Question

I have this

<ul id="myNavigation">
    <li><a href="https://my-website.com/page-1.html" title="Page 1">Page 1 (34)</a></li>
</ul>

I copy and replace the LINK, TITLE and NUMBER to this new css:

<div class="categories-name">
   <a href="https://my-website.com/page-66.html" title="Page 66">
   <p class="font-16 color-grey text-capitalize"><i class="fa fa-angle-right font-14 color-blue mr-1"></i> Page 66 <span>27</span> </p>
  </a>
</div>

I wonder if something like this can be done in powershell

The output should be:

<div class="categories-name">
   <a href="https://my-website.com/page-1.html" title="Page 1">
   <p class="font-16 color-grey text-capitalize"><i class="fa fa-angle-right font-14 color-blue mr-1"></i> Page 1 <span>34</span> </p>
  </a>
</div>

Hi @Suzana Eree ,

You can implement the loop like this

$file1 = 'D:\temp\file1.html'  
$file2 = 'D:\temp\file2.html'  
$result = 'D:\temp\result.html'  
$link=@()  
$title=@()  
$number=@()  
Get-Content -Path $file1 -Delimiter '</li>'|ForEach-Object{  
    $_|ForEach-Object{  
        if($_ -match '(?<=href=").+?(?=")'){$link += $Matches.Values}  
        if($_ -match '(?<=title=").+?(?=")'){$title += $Matches.Values}  
        if($_ -match '(?<=\()\d+(?=\))'){$number += $Matches.Values}  
    }  
}  
$content = Get-Content -Path $file2 -Delimiter '</div>'  
for($i=0;$i -lt $content.Count;$i++){  
    $content[$i] | ForEach-Object{  
        if($_ -match '(?<=href=").+?(?=")'){$link2 = $Matches.Values}  
        if($_ -match '(?<=title=").+?(?=")'){$title2 = $Matches.Values}  
        if($_ -match '(?<=<span>)\d+(?=</span>)'){$number2 = $Matches.Values}  
    }  
    $content[$i] -replace $link2, $link[$i] -replace $title2, $title[$i] -replace $number2, $number[$i] | Out-File -FilePath $result -Append  
}

hi @Anonymous

thank you, super answer ! But, maybe you have a complete solution in the case there are much lines, the same number of lines, the same structure, except the strings that needs to be parsing. I believe a Loop is need it ! Something like THIS or THIS

<ul id="myNavigation">  
<li><a href="https://my-website.com/page-1.html" title="Page 1">Page 1 (34)</a></li>  
<li><a href="https://my-website.com/page-2.html" title="Page 2">Page 2 (29)</a></li>  
<li><a href="https://my-website.com/page-3.html" title="Page-3">Page 3 (11)</a></li>  
....  
<li><a href="https://my-website.com/page-40.html" title="Page-4">Page 4 (54)</a></li>  
</ul>  

AND THE SECOND PART:

<div class="categories-name">  
        <a href="https://my-website.com/page-66.html" title="Page 66">  
        <p class="font-16 color-grey text-capitalize"><i class="fa fa-angle-right font-14 color-blue mr-1"></i> Page 66 <span>27</span> </p>  
     </a>  
</div>  
<div class="categories-name">  
     <a href="https://my-website.com/page-67.html" title="Page 67">  
     <p class="font-16 color-grey text-capitalize"><i class="fa fa-angle-right font-14 color-blue mr-1"></i> Page 67 <span>24</span> </p>  
</a>  
</div>  
<div class="categories-name">  
    <a href="https://my-website.com/page-68.html" title="Page 68">  
    <p class="font-16 color-grey text-capitalize"><i class="fa fa-angle-right font-14 color-blue mr-1"></i> Page 68 <span>07</span> </p>  
    </a>  
</div>  
.....  
<div class="categories-name">  
    <a href="https://my-website.com/page-100.html" title="Page 100">  
    <p class="font-16 color-grey text-capitalize"><i class="fa fa-angle-right font-14 color-blue mr-1"></i> Page 100 <span>67</span> </p>  
</a>  
</div>  

Answer 4

Hi @Suzana Eree ,

You can try some regexes like below

$file1 = 'D:\temp\file1.html'  
$file2='D:\temp\file2.html'  
$result = 'D:\temp\result.html'  
 Get-Content -Path $file1|ForEach-Object{  
    if($_ -match '(?<=href=").+?(?=")'){$link = $Matches.Values}  
    if($_ -match '(?<=title=").+?(?=")'){$title = $Matches.Values}  
    if($_ -match '(?<=\()\d+(?=\))'){$number = $Matches.Values}  
}  
$content = Get-Content -Path $file2  
$content | ForEach-Object{  
    if($_ -match '(?<=href=").+?(?=")'){$link2 = $Matches.Values}  
    if($_ -match '(?<=title=").+?(?=")'){$title2 = $Matches.Values}  
    if($_ -match '(?<=<span>)\d+(?=</span>)'){$number2 = $Matches.Values}  
}  
$content -replace $link2, $link -replace $title2, $title -replace $number2, $number | Out-File -FilePath $result
