From 4a6c9e445149e42a4f81d5140296e7770c60bc6c Mon Sep 17 00:00:00 2001 From: Brion Vibber Date: Thu, 18 Mar 2010 17:55:21 -0700 Subject: [PATCH] Work around weird bug with HTML normalization via PHP DOM module; if source had xmlns and xml:lang I ended up with double output, breaking the subsequent parsing. Will have to track this down later and report upstream if not already resolved. --- plugins/OStatus/extlib/hkit/hkit.class.php | 2 +- plugins/OStatus/lib/discoveryhints.php | 21 ++++++++++++++++++++- 2 files changed, 21 insertions(+), 2 deletions(-) diff --git a/plugins/OStatus/extlib/hkit/hkit.class.php b/plugins/OStatus/extlib/hkit/hkit.class.php index c3a54cff65..fec6f4d8fd 100644 --- a/plugins/OStatus/extlib/hkit/hkit.class.php +++ b/plugins/OStatus/extlib/hkit/hkit.class.php @@ -472,4 +472,4 @@ } -?> \ No newline at end of file +?> diff --git a/plugins/OStatus/lib/discoveryhints.php b/plugins/OStatus/lib/discoveryhints.php index 4da2ec0f1e..0273b5a92c 100644 --- a/plugins/OStatus/lib/discoveryhints.php +++ b/plugins/OStatus/lib/discoveryhints.php @@ -174,6 +174,26 @@ class DiscoveryHints { error_reporting($old); if ($ok) { + // If the original had xmlns or xml:lang attributes on the + // , we seen to end up with duplicates, which causes + // parse errors.
