How to use PHP snippets in Drupal

Enable the core 'PHP filter' module, then select the PHP filter from the 'input formats' list when creating a page.

Using Java classes from XSLT under Coocon / JBoss

Possible MD5 methods:
<xsl:value-of select="md5:encode('$term')" xmlns:md5="java:org.jboss.security.Base64Encoder" />
<xsl:value-of select="md5:encodeString($term,'ISO-8859-1')" xmlns:md5="java:org.hsqldb.lib.MD5" />

Search through built-in classes in JBoss:
find /path/to/jboss-4.2.2.GA/server/default/ -name "*.jar" -exec jar tf {} \; | grep MD5 -H

Parents node's position in XSL

1. Count parents using <xsl:number>
Number can be extracted:
($n)=$c=~/(\d+)\.\d+\.\d+\.\d+$/;
and adjusted:
$n=((($n/2)-5)+1)

<xsl:number count="." level="multiple" from="/page" format="1"/>

Or with format="a", interpret like j=1, l=2, n=3, p=4, etc.

2. Count parents using position()
Simpler -- but apparently this is a weird way to do it. Probably inefficient too.

<xsl:value-of select="count(parent::*/parent::*/parent::*/preceding-sibling::*) - 3"/>

Read an internal Apache variable

...such as %{MY_MOD_OUTPUT_NOTE}n -- that would be available for logging, but not visible by mod_include.

RewriteEngine On
RewriteRule ^(.*)$ $1 [E=MY_MOD_ENV_VAR:%{ENV:MY_MOD_OUTPUT_NOTE}]

Apache: make file download instead of appear in browser

Apache error "premature EOF in parsed file"

When Apache 1.3 says "premature EOF in parsed file".
What it means is "You've messed up the attribute syntax in a mod_include command".

Examples:

<!--#config timefmt=%s --> (no quotes)

<!--#set var='title' value='This title would've screwed things up' --> (apostrophe not escaped)

JSP/XSP generator in Cocoon

Warning: Untested.

In the sitemap.xmap:

<map:match pattern="^(\d+)$" type="regexp">
<map:generate type="serverpages" src="sfapi.xsp">
<map:parameter name="feedid" value="{1}"/>
</map:generate>

<xsp:logic>
int feedid=0;
try {
feedid = Integer.parseInt(parameters.getParameter("feedid"));
} catch (Exception e) {

XSL to copy XML

Andy's way:

<xsl:stylesheet version="1.0" xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes">
<xsl:template match="node() | @*">
<xsl:copy>
<xsl:apply-templates select="@* | node()">
</xsl:apply-templates>
</xsl:copy>
</xsl:template></xsl:output></xsl:stylesheet>


Another way:

<!-- copy the whole document -->
<xsl:template match="*">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="@*|text()|comment()|processing-instruction">
<xsl:copy-of select="."/>
</xsl:template>

Case sensitive MySQL column

Make a case sensitive varchar column:

CREATE TABLE `page_dm` (
`url` varchar(500) CHARACTER SET latin1 COLLATE latin1_bin NOT NULL,
) ENGINE=MyISAM DEFAULT CHARSET=latin1;
