Supremely flattered!:) I was amazed by the many things one can do with xpath, hope it will be used. Thank you!

Version 8: now can also query databases, JSON objects and (even if it does not make much sense) serialized arrays.

Version 0.88: enhanced special patterns with sanitizer functions (many thanks to Gocom for alerting me). Dropped preparse attribute.

Is there a way to do both numbered links and prev/next links in article_custom pagination? I’d like to use it for that, but thought I’d ask first.

You mean prev/next page? With one query it is tricky (in the current version), since we have to display some nodes twice, with different attributes. But with two queries it is possible (takes less than 0.005 extra seconds).

Suppose the navigation is driven by some url variable, say pgc. We firstly create the pagination list and store it in some variable:

<txp:variable name="pgc_list">
<txp:etc_query
  data='<txp:article_custom limit="999"><a href=''<txp:permlink />''><txp:title /></a></txp:article_custom>'
  query="a[position() mod 10 = 1]"
>
<a href="?pgc={#row}">{#row}</a>
</txp:etc_query>
</txp:variable>

Then in the article form put

<txp:if_individual_article>
<txp:variable name="pgc_list" />
<txp:else />
<txp:etc_query
  data='<txp:variable name="pgc_list" />'
  query="a[{?pgc|1|intval}]"
  globals="_GET"
  replace="preceding-sibling::a[position()=1]=Previous;following-sibling::a[position()=1]=Next"
>
{preceding-sibling::a[position()=1]}
<txp:variable name="custom_list" />
{following-sibling::a[position()=1]}
</txp:etc_query>
</txp:if_individual_article>

The article form can be completed with current page articles, enhanced with first/last links, restricted to showing at most n page links, and so on Please feel free to experiment, I will be glad to help .

Thank you, I’m trying that code out now. I’m going to try to troubleshoot, but I’m getting this error. Any advice is appreciated.
