Can not combine "if match=" and "when test"

K

kmunderwood

I am trying to combine "if match=" and "when test"
I am a newbie, and have made both work separately, but I can not seem
to combine them.


This is my xml("index.xml")page(I can not change this, it comes to me
this way.


<?xml version="1.0" encoding="iso-8859-1" ?>
- <fieldgate ser="6C000D010A0" tag="TTL Bulk Storage Farm" type="full"
devices="all">
<time>19700101-000000</time>
<timezone>0</timezone>
<ff_version>01.02.02-071 20050118</ff_version>
<os_version>3.18</os_version>
<conf>FXA520-AA1A</conf>
- <device id="11183312ee" tag="B05" type="HART">
<u4>°C</u4>
<v4>22.22</v4>
<u2>In H2O</u2>
<dev>Cerabar S</dev>
<man>Endress+Hauser</man>
<u1>lb</u1>
<v1>535.91</v1>
<type>HART</type>
- <param>
<t1ch>Bulk Tank B5</t1ch>
<t2ch>Weight in Pounds</t2ch>
<max>43928.00</max>
<min>0.00</min>
</param>
</device>
</fieldgate>


The "device" element repeats 11 more times,(tag number changes) and I
want to ignore some,
so I am using an "if match".
I just repeat the table for each bulk tank that I want to display.


This is my "if match" xsl("index.xsl"):
It works, but I can not make a v1 under 2000, have the background
change color


<?xml version='1.0'?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl">
<xsl:template match="/">
<html>
<body>
<table width="800" border="2" bordercolor="#3300CC"
bgcolor="#0099CC">
<tr>
<th>Tank #</th>
<th>Current Level</th>
<th>Temp.</th>
</tr>
<xsl:for-each select="fieldgate/device">
<xsl:if match=".[tag='B01']">
<tr>
<td width="200"><xsl:value-of select="tag"/></td>
<td width="200"><xsl:value-of select="v1"/></td>
<td width="200"><xsl:value-of select="v4"/></td>
</tr>
</xsl:if>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>


This shows an html page like this:
Tank # CurrentLevel Temp.
B01 395.47 69.65

I want the cell background to change to red when the level is below
2000


This is my "when test" xsl("index2.xsl"):
It works, but shows all tags, and I want to ignore some.


<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"><xsl:template
match="/">
<html>
<body>
<h2>My CD Collection</h2>
<table border="1">
<tr bgcolor="#9acd32">
<th>Tank</th>
<th>Level</th>
</tr>
<xsl:for-each select="fieldgate/device">
<tr>
<td><xsl:value-of select="tag"/></td>
<xsl:choose>
<xsl:when test="v1 &lt; 100">
<td bgcolor="#ff00ff">
<xsl:value-of select="v1"/></td>
</xsl:when>
<xsl:eek:therwise>
<td><xsl:value-of select="v1"/></td>
</xsl:eek:therwise>
</xsl:choose>
</tr>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template></xsl:stylesheet>



This is my html:

<html>

<head>
<style type="text/css">
th, td { font-size: 200%; }
</style>

</head>
<body>


<script language="javascript">
// Load XML
var xml = new ActiveXObject("Microsoft.XMLDOM")
xml.async = false
xml.load("index.xml")

// Load the XSL
var xsl = new ActiveXObject("Microsoft.XMLDOM")
xsl.async = false
xsl.load("index.xsl")

// Transform
document.write(xml.transformNode(xsl))
</script>

</body>
</html>


I have tried various combinations, to no avail.
If you can not help, can you suggest an article or suggestions on which
way to go?

<xsl:if match

xsl:if does not have a match attribute it has a test attribute.


=".[tag='B01']">

You can't use [] predicates after .
just use
="tag='B01'"

OK, What can I use to get the controlled results that I am looking for?
Out of all of the ways to extract xml data and put it into a web page,
which should I learn to do?

Can I change the following xsl, and apply a "choose", and "when test"
to get only the tag='B01' to show up?
When I try to do this, the result is a "true" display in the column for
tag='B01', and a "false" for the other tags.
Can I trick it somehow?
I will learn whatever method will give me the controls I need.

Thanks, Ken

most likely but you'd have to give some hint about the criterion that
you want to use.

I also note that in your sample posted earlier tag was an attribute of
device

but you have

<td><xsl:value-of select="tag"/></td>

which would select an element, so selects nothing in this case you need
@tag to select an attribute node.

OK, I want to
1. Only show the <tag> that want to, and
2. Turn an attribute a color when it falls below a certain level.


This is the way I want the html to display:


Tank Level Temperature
B05 535.91 22.22

535.91 background turns red, the way I need it to.
But, the way it pulls in all "Tag"
It looks like:


Tank Level Temperature
B05 535.91 22.22
B04 42567.36 22.81
_4..20mA-2 -0.01 <no data>


I want to ignore the _4..20mA-2, among others.
When the tank level falls below 600, I want the background or text to
turn red.


This is the way I get the xml.
(its abreviated. It is very long and shows 17 "Tag", or devices, but I
only want to show 12 of them)

The full xml file can be viewed here:
http://home.earthlink.net/~kmunderwood/index.xml



<?xml version="1.0" encoding="iso-8859-1" ?>
<fieldgate ser="6C000D010A0" tag="TTL Bulk Storage Farm" type="full"
devices="all">
<timezone>0</timezone>

<v1>-0.01</v1>
<man>Endress+Hauser</man>
<unid>_4..20mA-2</unid>
</device>
</fieldgate>


This is the xsl:


<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Tra­nsform"><xsl:templatematch="/">

This works fine, but includes all "tag", and I want to ignore some.


Tank Level Temperature
B05 535.91 22.22
B04 42567.36 22.81
_4..20mA-2 -0.01 Blank


The 535.91 background turns red, which is what I am looking for, but I
want to ignore <tag> _4..20mA-2
Plus, this way, it sorts all wrong.
I would like to show only 1 tank in the code, then I can repeat it in
separate tables and do whatever I want.

I had success displaying only the ones I wanted, using an "if match".
<xsl:if match=".[tag='B05']">, but I cant "test" on it.


This is the HTML:


<html>


<head>
<style type="text/css">
th, td { font-size: 200%; }
</style>
</head>


<body>


<script language="javascript">
// Load XML
var xml = new ActiveXObject("Microsoft.XMLDO­M")
xml.async = false
xml.load("index.xml")


// Load the XSL
var xsl = new ActiveXObject("Microsoft.XMLDO­M")
xsl.async = false
xsl.load("index.xsl")


// Transform
document.write(xml.transformNo­de(xsl))
</script>


</body>
</html>



If can can give me a few a clues to work on,
I Thank You, Ken

Click to expand...
That's because you select them all

<xsl:for-each select="fieldgate/device">
If you only want some of them, just select the ones you want, I can't
work out what that is but

<xsl:for-each select="fieldgate/device[not(starts_with(@tag,'_'))]">

wouldn't select those with a tag attribute starting with _ so
I want to ignore <tag> _4..20mA-2
Click to expand...

for example.

Not of you were using XSLT, a match attribute on xsl:if and a [
following a . are both fatal syntax errors and you would get no output.
You must have been using the Microsoft-specific transformation language
built in to IE5 (and supported in msxml3/IE6 for backwards
compatibility) The code you show however is in the XSLT namespace not
the namespace for that now deprecated language.
