how to extract from _inside_ xml tag

[edfialk]

here's my xml:

<dimension name="lat" units="degrees_north"
dim_type="index">
<min>-90</min>
<max>90</max>
<count>181</count>
</dimension>
<dimension name="lon" units="degrees_east"
dim_type="index">
<min>-180</min>
<max>179</max>
<count>360</count>
</dimension>
I'm having difficulty finding out which of these tags are name="lat"
and which are name="lon".
right now I have:
<xsl:for-each select="/dataset/LatLonTimeCube/dimensions/
dimension">
<xsl:if test="name=lon">
&lt;westbc&gt;<xsl:value-of select="min"/>&lt;/westbc&gt;
&lt;eastbc&gt;<xsl:value-of select="max"/>&lt;/eastbc&gt;
</xsl:if>
<xsl:if test="name=lat">
&lt;northbc&gt;90&lt;/northbc&gt;
&lt;southbc&gt;-90&lt;/southbc&gt;
</xsl:if>
</xsl:for-each>

I know the 90 in there is a constant, I was just testing.

For the above xml, I need to print out:

west: -179
north: 90
east: 180
south: -90

BUT, my if test="name=lon" is always failing. Does anyone know how to
test the value of name from inside the dimension tag?

I would extremely appreciate any help.
Thanks!

<xsl:if test="name=lon">

That compares the value of the <namechild element against the value of
the <lonchild element -- which of course doesn't exist. Change it to

<xsl:if test="name='lon'">

Hey Joe thanks, but it still doesn't seem to be passing the test.

<xsl:if test="name='lon'">
&lt;westbc&gt;<xsl:value-of select="min"/>&lt;/westbc&gt;
&lt;eastbc&gt;<xsl:value-of select="max"/>&lt;/eastbc&gt;
</xsl:if>

<xsl:if test="name='lat'">
&lt;northbc&gt;90&lt;/northbc&gt;
&lt;southbc&gt;-90&lt;/southbc&gt;
</xsl:if>

doesn't output anything because it's still failing the test.
If I change the ifs to a choose/otherwise, the otherwise is getting
printed, because it's failing the test.

Any other ideas?

By the way,

&lt;westbc&gt;<xsl:value-of select="min"/>&lt;/westbc&gt;

is *****EXTREMELY***** bad practice. If you want to construct XML
output, use literal XML or the appropriate XSLT directives.

<westbc><xsl:value-of select="min"/></westbc>
or
<xsl:element name="westbc"><xsl:value-of select="min"/></xsl:element>
As to why things aren't matching: I'll take another look, but I suspect
you've given us an incomplete description of your problem.

Ya, I've never used XSL before, my co-worker has come to me with this
problem hoping I can help. I'll make her change her output structure.

As for my problem, I'm not sure what else to include. i can't attach
files, but basically I've got:

<dimension name="lat" units="degrees_north"
dim_type="index">
<min>-90</min>
<max>90</max>
<count>181</count>
</dimension>
<dimension name="lon" units="degrees_east"
dim_type="index">
<min>-180</min>
<max>179</max>
<count>360</count>
</dimension>

and:

<xsl:for-each select="/dataset/LatLonTimeCube/dimensions/dimension">
<xsl:choose>
<xsl:when test='name="lat"'>
SUCCESS!
</xsl:when>
<xsl:otherwise>
failed
</xsl:otherwise>
</xsl:choose>

should output one SUCCESS and one failed, but it's always failed.
I would be happy to host these 2 files on my server so anyone could
take a look at them if they wish.

Including a minimal runnable example is usually a good idea -- a
complete input file, and a complete stylesheet, both trimmed down to
absolute essentials needed to demonstrate the problem.

If they're short enough that we don't get bogged down in irrelevant
detail, that will do the job. If not, trim 'em down first, them post.

(Among other things, the process of trying to reduce the problem to its
simplest form is often enough by itself to expose the mistake.)

As name is an attribute, it must be "@name='lon'" instead.

Blush. Can't believe I missed that typo...
