rah_replace - Search and replace

GugUser · 2011-07-01 02:02:43

Your idea in #13 works. I’ve adapted it to my needs:

<txp:output_form form="head" />
	<body id="<txp:section />">
		<div id="wrapper">
			<txp:rah_replace from="http://domain.de" to="">
				<txp:output_form form="slider" />
			</txp:rah_replace>
			<section>
			<txp:if_section name="impressum,kontakt">
				<h1>normal title</h1>
				<txp:article limit="1" sort="position asc" form="artikel" />
			<txp:else />
				<txp:rah_replace from="http://domain.de" to="">
					<h1><txp:if_section name="xy">XY title<txp:else />Normal title</txp:if_section></h1>
					<txp:article limit="1" sort="position asc" form="artikel" />
				</txp:rah_replace>
			</txp:if_section>
			</section>
			<txp:rah_replace from="http://domain.de" to="">
				<txp:output_form form="nav" />
				<txp:output_form form="footer" />
			</txp:rah_replace>
		</div>
	</body>
</html>

It could be that in my first version the HTML5 element <section> interferes with <txp:if_section>. I don’t know it.

Markup has no effect to server-side Textpattern tags, the element isn’t interfering. It’s all about the nesting of the tags. A block needs to be closed on the same level as it was opened. An open parent container tag can not be closed inside a child block.

In your first version you had structure outline is similar to:

<foo>
	<bar>
		</foo>
	</bar>

Such block nesting isn’t possible. Closing foo should be outside bar:

<foo>
	<bar>
	</bar>
</foo>

That was the reduced scheme of my first code:

<txp:rah_replace from="http://domain.de" to="">

	HTML group 1

	<txp:if_section name="kontakt">
		</txp:rah_replace>
	</txp:if_section>

	HTML group 2

	<txp:if_section name="kontakt">
		<txp:rah_replace from="http://domain.de" to="">
	</txp:if_section>

	HTML group 3

</txp:rah_replace>

My intention was that the three HTML groups 1-3 are within one rah_relace, except in the section “kontakt” in which the HTML group 2 is excluded. That would be possible with HTML elements, but not with closing and opening Textpattern tags.

Thank you Els and Gocom for your answers and comments.

Hi Jukka – a hopefully easy question if you’re around and reading this thread: I’d like to be able to remove everything between <txp:rah_replace> and </txp:rah_replace>, primarily so I can leave comments in a form/page/etc without it being seen on the front end and reduce load times. Is there a wildcard operator for from in this instance?

Thanks in advance!

HI Pete,

I usually use <txp:hide> ... your memory dump here ... </txp:hide> for this.

gaekwad · 2012-02-06 15:12:27

Hi Jakob – perfect, thank you very much.

I have a site requirement to replace every other instance of a word – not every instance as normal use of rah_replace would be.

Example: If cat were on the page four times, I need the 2nd and 4th instances to become dog.

Is there a simple tweak to rah_replace that would get this done?

Sorry, no, not exactly.

Reminds me of zebra stripes. ~~You could set up such an if_variable conditional around your replacing arrangements.~~ No, don’t even try :P

Mmm… I have a vision of a combo of rvm_counter, txp:variable and if_variable and at least two instances of rah_replace… and maybe some smd_query and smd_if to finish it off… ;)

Ugh, breaking these bubbles. I’m a meanie.

Sorry, but unfortunately, not going to work. You can’t effect rah_replace’s search-and-replace routine in shape or any form. You will need sub-string replacing that has movable pointer, which isn’t what rah_replace does. It always replaces all occurrences, and not even words, i.e. catwomen becomes dogwomen.

Only way you could even theory make it work with rah_replace is to create sub-strings prior to running rah_replace by splitting each words and then joining the results back together. In which point rah_repleace becomes obsolete as you already have individual words to do 1on1 replacing (no search needed).

and maybe some smd_query and smd_if to finish it off… ;)

I don’t see none of those, as it stands, doing it either. Smd_query has no relation to the case at all. It builds DB queries and that is it.

Haha, not a surprise :) I didn’t think very hard about it. Just curious, is something like this complete nonsense?

<txp:variable name="dogs" value="0" />
<txp:rah_replace from="dog<!-- 2 -->,dog<!-- 4 -->,dog<!-- 6 -->" to="cat,cat,cat">
   <txp:rah_replace from="dog" to='dog<!-- <txp:adi_calc name="dogs" add="1" display="1" /> -->'>
      text with dogs goes here
   </txp:rah_replace>
</txp:rah_replace>

To answer my own question, yes, I expect it is ;)

Thank you. I can let go now ;)

Thank you all for having a try at this. I might just have to let it go too…
