PhpXpath 3.3

[Dan <xp...@da...>]

First of all, sorry about my last post (php 
allow_call_time_pass_reference 03/23/2003).  At the time, I don't know 
why, but I couldn't find any info.  I now have read the posts previosu 
to mine and understand the issue.  If you are an administrator and can 
delete that post, please do (along with this part of this message if 
possible).

I have another issue now that I can't seem to find any info on.  Using 
phpXpath 3.3 I am able to import xml using both the importFromFile() 
and importFromString() methods. I am also able to use the getData() and 
exportAsXml() methods.  However my application calls for using 
appendChild() / insertChild() and insertData() calls inbetween.  For 
some reason, my appendChild() calls are returning the following errors:

XPath error in oop.xpath.php:1673 In importFromString(): XML error in 
given string on line 1 column 0. Reason:syntax error

XPath error in oop.xpath.php:5272 XPath error in oop.xpath.php:1673. 
Message: In importFromString(): XML error in given string on line 1 
column 0. Reason:syntax error

When I comment out the appendChild() call, both errors disappear.  I 
tried setting $bDebugThisFunction of importFromFile() to true, and got 
the following (abbreviated) output:

Setup for parse 1 ms
Parse Object 4 msArray
(
     [0] =>
     [1] => /text()[1]
     [2] => /MyRootNode[1]
     [4] => /SubNodeOne[1]/text()[1]
...
     [22] => /SubNodeOne[1]/text()[3]
     [23] => /text()[2]
)

My appendChild() call looks like this:

$XpathObject->appendChild("/MyRootNode[1]/SubNodeOne[1]", "SubNodeTwo");

Is the error coming from a problem with my method call, or is it from 
the fact that the zero element of this array is empty / null?  How can 
I fix this?  I tried substituting the version 2.2 class source file 
instead of version 3.3, and everything works fine.  After viewing my 
xml files using several text editors, I've come to the conclusion that 
the error is not because of whitespace at the beginning of the 
document.  I get this error from both importFromString() and 
importFromFile(), since the latter actually calls the first. Can anyone 
shed any light on why this is happening?  Thanks!

  First of all, sorry about my last post (php =
allow_call_time_pass_reference 03/23/2003). At the time, I don't know =
why, but I couldn't find any info. I now have read the posts previosu to =
mine and understand the issue. If you are an administrator and can =

possible).
The issue was always somewhat fuzzy in my mind, so I was hoping someone =
else would chip in and answer your question.... the email was still in =
my inbox :o/  Glad you got the answer you were looking for though!
  I have another issue now that I can't seem to find any info on. Using =
phpXpath 3.3 I am able to import xml using both the importFromFile() and =
importFromString() methods. I am also able to use the getData() and =
exportAsXml() methods. However my application calls for using =
appendChild() / insertChild() and insertData() calls inbetween. For some =
reason, my appendChild() calls are returning the following errors:
<snip>
  My appendChild() call looks like this:

  $XpathObject->appendChild("/MyRootNode[1]/SubNodeOne[1]", =
"SubNodeTwo");
Try=20

$XpathObject->appendChild("/MyRootNode[1]/SubNodeOne[1]", =
"<SubNodeTwo/>");

is happening? Thanks!

It was a change in the appendChild() call between 2.2 and 3.3 that we =
obviously didn't document well enough (you aren't the first to get stung =
by this).  Previously you could only append a single new element, but =
now you can do cool stuff like=20

$XpathObject->appendChild("/MyRootNode[1]/SubNodeOne[1]", =
"<a><b/><c/></a>");

Cheers
