Rename a HTML file based on the content of a tag

I have a lot of html files that I want to rename according to the content of
the tag h1.

Any suggestion on how to do it on bash?

Example of a file:

<!DOCTYPE html><html lang="pt-BR"><head><meta charset="utf-8"><title>RepositÃƒÂ³rio - MAIS</title>
 <script src="lib/tudo.js"></script>
 <link rel="stylesheet" href="lib/style.css">
</head>
<body>
<div id="cabecalho"></div>
<div id="corpo">
<h1>teste</h1>

<div class="Experimento"></div>
<div class="gallery">
<img class="image-gallery" src="img/2dados.png">
</div>

<br><br><strong>MÃƒÂdia:</strong> experimento (uma aula dupla)

<br><br><strong>DescriÃƒÂ§ÃƒÂ£o:</strong> este experimento propÃƒÂµe 4 jogos diferentes, todos baseados no lanÃƒÂ§amento de 2 dados comuns. Discutindo as chances de cada jogador vencer cada um dos jogos, os estudantes terÃƒÂ£o a chance de discutir vÃƒÂ¡rios conteÃƒÂºdos relacionados ÃƒÂ  probabilidade

<br><br><strong>ConteÃƒÂºdo:</strong> experimento aleatÃƒÂ³rio, espaÃƒÂ§o amostral, eventos equiprovÃƒÂ¡veis, probabilidade

<br><br><strong>RecomendaÃƒÂ§ÃƒÂ£o de uso:</strong> este experimento pode ser usado como introduÃƒÂ§ÃƒÂ£o ou aplicaÃƒÂ§ÃƒÂ£o dos conceitos iniciais de probabilidade.

<br><br><strong>Autoria:</strong> este experimento foi desenvolvido pela <a class="externo" href="http://www.mais.mat.br" target="_blank">Mais</a> e pode ser utuilziado e distribÃƒÂdo livremente, contanto que citada a autoria original.

<a class="download" href="http://www.mais.mat.br/recursos/images/5/5b/2dados.pdf">Baixar</a>

</div>
<div id="rodape"></div>
</body>
</html>

I want the file renamed to "teste.html"

If it is helpful, this tag is always on the 8th line of each file and alone (nothing else on the same line). Also, there is always only one occurrence of h1 in each file.

With xmllint :

File:

<!DOCTYPE html>
<html>
 <head>
 <title>test</title>
 </head>
 <body>
 <a>foo</a>
 <b>bar</b>
 <c>base</c>
 </body>
</html>

Command:

for file in *.html; do
 tag=$(xmllint --xpath '//b/text()' $file)
 echo mv "$file" "$tag_$file"
done

Comment:

Put off the echo command when your tests become ok to run the command for real

maybe echo mv "$file" "$tag_$file" - that way the quotes are still correct if echo is deleted from the line. Also, why not put in a <h1>...</h1> example since that's what the OP wanted? finally, a pipe to head -n 1 would be useful in case there's more than one h1 tag.

The right way with find + xmlstarlet tools:

find . -type f -name "*.html" -exec sh -c 
'name=$(xmlstarlet sel -t -v "//tagname" $1 2>/dev/null); 
 [ ! -z "$name" ] && echo mv "$1" "$1%%/*/$name.html"' _ ;

name - variable which is assigned with a value (the contents of the tag tagname) for the new filename

[ ! -z "$name" ] - check if a new filename is not empty (i.e. <tagname> was found and it had a value)

If tag is alone on the 8-th line, you have many way to pick it.

tag=$( awk NR==8 file )

tag=$( awk 'NR == 8 print ;' file )

where

NR is number of record (line number)

print is implied action

tag=$(sed -n 8p file)

where

-n will not echo line

8p print 8th line.

and many other.

as notted in comment, relaying on line number is risky. If file is a valid xml file, extracting tag would be easier and safest.

My final solution was the code below, combining two suggestions. Thank you, guys!

for file in *.html; do
 tag=$(xmlstarlet format --html $file | xmlstarlet select --html --template --value-of '//html/body/div/h1')
 mv "$file" "$tag.html"
done

It worked great for my files!

With xmlstarlet:

xmlstarlet format --html teste.html | xmlstarlet select --html --template --value-of '//html/body/div/h1'

Output:


teste

I used xmlstarlet format --html teste.html to fix your non valid html code.

If tag is alone on the 8-th line, you have many way to pick it.

tag=$( awk NR==8 file )

tag=$( awk 'NR == 8 print ;' file )

where

NR is number of record (line number)

print is implied action

tag=$(sed -n 8p file)

where

-n will not echo line

8p print 8th line.

and many other.

as notted in comment, relaying on line number is risky. If file is a valid xml file, extracting tag would be easier and safest.

My final solution was the code below, combining two suggestions. Thank you, guys!

for file in *.html; do
 tag=$(xmlstarlet format --html $file | xmlstarlet select --html --template --value-of '//html/body/div/h1')
 mv "$file" "$tag.html"
done

It worked great for my files!
