Ok, this must be simple but the more i search the more i don't find.
How to find non-existing nodes or nodes with no text

My XML file looks a little bit like this:

i.e. 1
<discography>
<CD>
<title></title>
<year>1978</year>
</CD>
</discography>

i.e. 2:
<discography>
<CD>
<year>1978</year>
</CD>
</discography>

In i.e. 1, the tag <title> is empty. How do i test for empty tags in
PHP?
In i.e. 2, the tag <title> doesn't even exist. How do i test for non-
existing tags?

This is how i get the values from XML in PHP without validation
....
//set the XML file name as a PHP string
$cd_xml = "db/discography/cd.xml"; //load the XML file$xml = @simplexml_load_file($cd_xml) or die ("Error: The XML file can't open.") ; .... //no validation if empty, creates empty <h1> tags. Not good! <h1><?php echo$xml->CD->title; ?></h1>
<h2><?php echo $xml->CD->year; ?></h2> How to validate? Any suggestions?

xsl variable $node/text() but$node can non-node-set help!
I have a variable $value as a parameter in the following template: <xsl:template name="myTemplate"> <xsl:param name="value"/> <xsl:if test="$value"> <xsl:value-of select="$value"/> </xsl:if> </xsl:template> Now i call myTemplate sometimes whit the a parameter$value that is sometimes a text node, and sometimes it is not even a node. Example: <inputDoc> <a>hello</a> <a/> </inputDoc> xsl: <xsl:for-each select="/inputDoc/a"> <xsl:call-template name="myTemplate"> <xsl:with-param name="value" select="./text()"/> </xsl:call-template> </xsl:for-each> So i call myTemplate with parameter $value=a/text() But for the second <a> element in <inputDoc> there is not text() node. This gives me the following error: Cause: javax.xml.transform.TransformerException: The value is not a node-set With line number of the error pointing to the xsl:if in myTemplate. No i tried the function nilled(), but that is XPath 2.0, i only use XPath 1.0 and XSL 1.0 i know a possible solution is this: <xsl:for-each select="/inputDoc/a"> <xsl:choose> <xsl:when test=".[not(node())]"> <xsl:call-template name="myTemplate"> <xsl:with-param name="value" select="false()"/> </xsl:call-template> <... simpleXML and PHP. How to find if a node is empty or exists? I think that simpleXML is the best thing i've seen in PHP5. It's so simple (d'ho!) and easy to use when it comes to reading a simple XML file. The only thing i'm not sure how to achieve is finding if an XML node is empty or if the node exist or doesn't exist. I'm searching the web, but got nothing yet. I was thinking of posting it here. This is a condensed version of the code: <?xml version="1.0" encoding="UTF-8"?> <CD> <title>Shine</title> <year>1985</year> <label></label> <description>Good CD from the 1980s</description> <item> <track id="18">Moonlight</track> <track>Shine</track> <track>Absolute</track> </item> <item> <track>Relative</track> <track>Star</track> <track>Crazy</track> </item> </CD>$file = 'db_cd_number.xml'; $xml = @simplexml_load_file($file); //?????? if(title node is empty || title node doesn't exist) { echo 'title is empty or doesnt exist, do something'; } else { echo 'title OK, continue'; } //i.e. 2 What about attributes?????????? foreach ($xml->item-> as$item) { foreach($item->track as$track) { if($track['id'] doesn't exist or empty) { echo 'dont show the lyrics'; ... Why treat text nodes as nodes? One of the things I find most unnatural about most XML APIs is that they try to abstract both elements and text into some kind of "node" object when they have virtually nothing in common. The reason these APIs do it is to make it possible for both text and elements to be children of elements. But there is another way. The XPath/XQuery data model does not allow two consecutive text nodes. As far as I can tell, most XML processing software automatically merges consecutive text nodes. This means that the number of text segments directly under an element is bound by the number of sub-elements plus 1 (PIs and comments may be treated as "pseudo-elements" for this purpose). As a result, it is always possible to associate each text segment with the element immediately preceding it within the parent and associate the first text element with the parent itself. No more text nodes. The only API I know that uses this trick is the ElementTree API for Python by Fredrik Lundh (http://effbot.org/zone/element-index.htm). Each Element object has a text and tail property for the text immediately inside the element and text following it within its parent element. Elements always have a tag, attributes and and zero or more children - which are always other elements. No mixed types. The text and tail attributes are always strings. This model should be very convenient for statically-typed languages like Java or C++. I find it ironic that this idea is probably used only in Pyt... Text nodes and element nodes query Hi all, The code below gets me a list of all the nodes within the node object called xml_tags_root. NodeList nl = xml_tags_root.getChildNodes(); The length of nodelist I get is double the number of actual elements! This is because after every element node there is text node which is (I think) the whitespace in the XML document. Is there a way to get only the element nodes?

Getting kind of abstract text snippets from text nodes
Hi everybody, I am about implementing a little search engine that searches a phrase over xml text nodes. I got that all working fine but what I want as the results is not the complete text of the textnode, I would like to make an abstract like result list (such output that you get with google searches. For eg .... I am the <b>substring</b> from a complete text node ... where "substring" is the search term. The problem is simple (I think): I want to extract all the text parts of the complete text node, where search searchterm is highlighted, surrounded by the text like 30 characters. I found an intersting post "cut down text" which is almost that what I am looking for, but there the text is just trimmed by x characters. Is anybody here, that has an "elegant" way to solve that or some hints that get me to the solution? I am not able to use regex (would be nice though) My parser is Sablotron so I am restricted to the functions that I get. (1.0).

I can't just use document.body.appendChild as the last node is likely to be a grandchild or great-grandchild of body.

I tried ping and it works perfectly. Meanwhile, I can still ssh from server to all other nodes successfully. How this happens is that I am running MPI programs (using MPICH) from the master node on the slave nodes using "mpirun -np 8 allgatherv2". Everything works fine until my program appear to consume too much on oscarnode1 (as seen from the /var/log/messages), forcing oscarnode1 to 'die'. Now, I can't 1) "ssh oscarnode1" 2) "mpirun -np 8 allgatherv2" (possibly caused by the 'dead' oscarnode1) output from /var/log/messages: ----------- Sep 7 20:19:09 oscarnode1 sshd(pam_unix)[2000]: session opened for user csyeo by (uid=0) Sep 7 20:20:56 oscarnode1 sshd(pam_unix)[2018]: session opened for user csyeo by (uid=0) Sep 7 20:21:17 oscarnode1 kernel: Out of Memory: Killed process 2001(allgatherv2).

I've been reading the Cluster Systems manual for ages but some points are still a bit obscure. My cluster: +--------------------------------------------------------+-----------------+ | SYSTEMS | MEMBERS | +--------+--------------------------------+--------------+-------+---------+ | NODE | HW_TYPE | SOFTWARE | VOTES | STATUS | +--------+--------------------------------+--------------+-------+---------+ | OKAPI | AlphaServer DS10L 617 MHz | VMS V8.3 | 1 | MEMBER | | DONKEY | HP rx2620 (1.60GHz/3.0MB) | VMS V8.3 | 1 | MEMBER | +--------+--------------------------------+--------------+-------+---------+ and I want to add a 3rd node, also ds10l. All nodes boot from MSA1000, OKAPI from$1$DGA1: and DONKEY from$1$DGA2: I set up the MSA LUNs via CLI, so the above disks names are as they appear in VMS. I understand that number "1" in the above disk names is a port allocation class. Is that correct? I assigned both nodes a node allocation class, also 1. Do I need to do this if the port allocation is already in use? I run DECnet-Plus on both nodes. Now I want to add a second alpha node (LLAMA) to the cluster, also to boot from$1\$DGA1. I run CLUSTER_CONFIG.COM from OKAPI, and specify that the page and swap files for the new cluster member will be on its local disk. At which point...
