Extracting text from / summarizing ezxmltext

Sunday 09 January 2005 1:25:01 am

Hi,
I want to be able to provide the first few words of an ezxmltext field in a template, but I can't seem to find a safe way of doing so.

The closest I can come is using shorten(), but that's not safe, as it doesn't understand xhtml, and can leave tags un closed.

I think the best way to achieve what I want, would be to extract all the raw text from the field, and then apply shorten on that, but that leads me to my problem.

Is there any way of extracting the raw text from an ezxmltext field?

Hi all,

To show only parts of xml, you have to strip the tags. (Otherwise you might end up cutting of inside a tag, or not have closed tags)

So, where you would normally use

{attribute_view_gui attribute=$node.data_map.attribute}

You need to use something like:

{$node.data_map.attribute.content.output.output_text|strip_tags|shorten(25)|wash}

To enable the striptags operator, you need to add the following in settings/override/template.ini.append.php

[PHP]
PHPOperatorList[strip_tags]=strip_tags

Hi,

I wrote an extension that does a shorten on a xmltext. It's able to deal with tags. It's able to replace the <p> by <br>. it's able to keep some tags (eg <a> and <b> and stip the others). Best of all, it secures ez publish, even if you allow literal class="html".

Right now, I'm not sure about what API/template this extension should offer.

May be the best place to discuss that is the ezpedia.

Let me clarify what I have done, upload it to the pubsvn and launch a talk about it.

Take care.

Thanks for this thread, I add this problem.
Added summarizing comment to the doc : http://ez.no/doc/ez_publish/technical_manual/3_8/reference/template_operators/strings/shorten

Ca, c'est fait !

I just got an idea here: You could do this with a special template operator "xmlshorten", which disregards tags when counting characters, and then automatically closes all open tags when desired length have been reached. Should not be too hard to implement...

Well, since you mention offering a beer to the one doing it ;)

This extension allows to shorten the xml result, even while keeping all (or a selection of) xml tags.

as an added bonus, it offers a bigger security, no matter your ez config, even while using the html class for the literal tag.

Hi all,

Xavier, your extension sounds like it will provide a good solution to this problem. Is it available to download anywhere yet, I looked at the project page but couldn't find a download?

I have just come up with a really stupid way to shorten the full message body of a blog post while retaining the format, say I have 2 paragraphs in the shortened text and I use striptags(), I lose the format of the paragraph tags, i.e. the 2 paragraphs become one.

I tried using the nl2br operator but found that it inserted 4 <br /> tags so I came up with a really convoluted solution that I really don't want to use if I don't have too:

{def $text=$blog.data_map.message.content.output.output_text|striptags|shorten(500, ' ...', right)}

<p>{$text|simplify('\n')|nl2br|nl2br} <a href={$blog.url_alias|ezurl}>More</a></p>

Nasty stuff, not what I would call an ideal solution, but it will do until I get my hands on xmlwash. ;)

Cheers.

Pardon me while I burst into flames...

@Nathan:

The problem is that there is not a packaged binary (tar.gz,bzip2,zip) at,
http://projects.ez.no/xmlwash/downloads
http://ez.no/community/contribs/template_plugins/xml_wash

And while there are links all pointing to the project,
http://projects.ez.no/xmlwash

At this point the source code is not available from the individual project repository,
http://projects.ez.no:81/svn/projects/xmlwash/

I did however today find a copy of the source code at PubSVN,
http://pubsvn.ez.no/community/trunk/extension/xmlwash/

For clarity sake a number of locations above could make a clear direction to the source code for users who are not familiar with the popular location for community source code. <i>@X.. This is why the user feedback was mute. It was a release clarity mixup...</i>

Got it, I looked at contribs the other day but must have overlooked it somehow. But I've got it now, thanks.

Cheers.
