i have conditional like this:
<xsl:variable name="MsgIdBs">
<xsl:variable name="dateB" select="substring($MsgIdB,1,8)"/>
<xsl:variable name="biCodeB" select="substring($MsgIdB,9,8)"/>
<xsl:variable name="trTpB" select="substring($MsgIdB,17,3)"/>
<xsl:variable name="snB" select="substring($MsgIdB,20,8)"/>
<xsl:choose>
<xsl:when test="not(fn:matches($MsgIdB, '^[a-zA-Z0-9]*$') and string-length($MsgIdB) <= 35)">
<xsl:copy>
<xsl:copy-of select="$MsgIdB"/>
</xsl:copy>
<xsl:variable name="flag" select="'false'"/>
</xsl:when>
<xsl:when test="not(number(substring($dateB, 1, 4)) >= 1970 and number(substring($dateB, 5, 2)) <= 12 and number(substring($dateB, 7, 2)) <= 31)">
<xsl:copy>
<xsl:copy-of select="$MsgIdB"/>
</xsl:copy>
<xsl:variable name="flag" select="'false'"/>
</xsl:when>
<xsl:when test="not(contains($trTpB,'010') or contains($trTpB,'011') or contains($trTpB,'019') or contains($trTpB,'110') or contains($trTpB,'510') or contains($trTpB,'610') or contains($trTpB,'710') or contains($trTpB,'720') or contains($trTpB,'000'))">
<xsl:copy>
<xsl:copy-of select="$MsgIdB"/>
</xsl:copy>
<xsl:variable name="flag" select="'false'"/>
</xsl:when>
<xsl:when test="not(fn:matches($snB, '^\d+$'))">
<xsl:copy>
<xsl:copy-of select="$MsgIdB"/>
</xsl:copy>
<xsl:variable name="flag" select="'false'"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$MsgIdB"/>
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
and i have a variable to check value from variable name flag. but i always get value from otherwise. never get value from variable flag on conditional. the code like this:
<xsl:variable name="output">
<xsl:choose>
<xsl:when test="$flag = 'false'">
<ns2:TxSts>Not Deal</ns2:TxSts>
</xsl:when>
<xsl:otherwise>
<ns2:TxSts>Deal</ns2:TxSts>
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
how i can get the value from variable name flag on conditional and compare base with variable output.
Create a seperate variable for flag. This will keep the flag varible in scope for use in following code.
<xsl:variable name="flag">
<xsl:variable name="dateB" select="substring($MsgIdB,1,8)"/>
<xsl:variable name="biCodeB" select="substring($MsgIdB,9,8)"/>
<xsl:variable name="trTpB" select="substring($MsgIdB,17,3)"/>
<xsl:variable name="snB" select="substring($MsgIdB,20,8)"/>
<xsl:choose>
<xsl:when test="not(number(substring($dateB, 1, 4)) >= 1970 and number(substring($dateB, 5, 2)) <= 12 and number(substring($dateB, 7, 2)) <= 31)">
<xsl:value-of select="'false'"/>
</xsl:when>
<xsl:when test="not(contains($trTpB,'010') or contains($trTpB,'011') or contains($trTpB,'019') or contains($trTpB,'110') or contains($trTpB,'510') or contains($trTpB,'610') or contains($trTpB,'710') or contains($trTpB,'720') or contains($trTpB,'000'))">
<xsl:value-of select="'false'"/>
</xsl:when>
<xsl:when test="not(fn:matches($snB, '^\d+$'))">
<xsl:value-of select="'false'"/>
</xsl:when>
</xsl:choose>
</xsl:variable>
Use the flag to create MsgIdBs.
<xsl:variable name="MsgIdBs">
<xsl:choose>
<xsl:when test="contains($flag, 'false)">
<xsl:copy>
<xsl:copy-of select="$MsgIdB"/>
</xsl:copy>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$MsgIdB"/>
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
Use the flag again to create output.
<xsl:variable name="output">
<xsl:choose>
<xsl:when test="contains($flag, 'false)">
<ns2:TxSts>Not Deal</ns2:TxSts>
</xsl:when>
<xsl:otherwise>
<ns2:TxSts>Deal</ns2:TxSts>
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
How would you convert JSON to XML?
Consider:
<sampleTag>
{
"Order": {
"InvestmentAccount": { "AccountNumber": "10" },
"Parcel": {
"Limit": "0",
"ExpiryDate": "1900-01-01T00:00:00",
"Asset": [
{
"Open": "25.15",
"High": "25.15",
"Low": "25.11",
"Close": "25.87"
}
{
"Open": "25.15",
"High": "25.15",
"Low": "25.11",
"Close": "25.87"
}]
},
"OrderDate": "2012-10-11T21:46:03.6489906+11:00",
}
}
</sampleTag>
After transformation, the document is as follows:
<Order>
<InvestmentAccount>
<AccountNumber>10</AccountNumber>
</InvestmentAccount>
<Parcel>
<Limit>0</Limit>
<ExpiryDate>1900-01-01T00:00:00</ExpiryDate>
<Asset>
<Open>25.15</Open>
<High>25.15</High>
<Low>25.11</Low>
<Close>25.87</Close>
</Asset>
<Asset>
<Open>25.15</Open>
<High>25.15</High>
<Low>25.11</Low>
<Close>25.87</Close>
</Asset>
</Parcel>
<OrderDate>2012-10-11T21:46:03.6489906+11:00</OrderDate>
</Order>
My work on JSON parsing doesn't cover the full JSON grammar.
And the task of "translating" any JSON document to an XML document doesn't have a solution. There are JSON constructs, which cannot be translated to XML without defining additional conventions and introducing additional elements -- so the final XML structure isn't a true and natural representation of the original JSON object.
In XSLT 3.0 there is a function to parse any JSON object -- parse-json() -- to a map -- a new data type introduced in XSLT 3.0. Read about this here:
http://www.w3.org/TR/xslt-30/#json
Actually, it is not that hard. The way to approach it is to examine the syntax of jason, and view each production like it was a template. I was just about to write a solution, when I considered the possibility that the OP forgot to google for pre-existing solutions. I searched and lo and behold ....
http://dnovatchev.wordpress.com/2007/07/05/transforming-json/
UPDATE
Here is a JSon to XML converter. But it only works on a subset of json. Hopefully, the subset is broad enough for your particular needs. In particular the limitations are:
The only simple type supported is string. No integer, boolean or null.
Json object names must be valid xml element names.
No escape codes permitted inside string values. This means that you cant transport values that include, for instance, the " character (without rolling your own encoding layer).

I tweaked Sean B. Durkin's template a bit and thought I'd share.
Updates include:
Support for numbers
Support for booleans
Fix for object array elements separated by a comma (per JSON spec)
Non-update changes:
Array elements are displayed in their own XML elements with the element name as the object key suffixed with _element
Still not supported:
Escaped characters (quotes) in strings
Here's the template:

The question is tagged for XSLT 1.0, so I do not know if this answer will help the original question. But if you can use XSLT 3.0, the function json-to-xml does exactly what you need.
https://www.w3.org/TR/xslt-30/#func-json-to-xml
As well as Dimitre's XSLT parsing framework, there is also Gunther Rademacher's Rex parser generator, which also includes JSON as one of its sample grammars:
http://www.bottlecaps.de/rex/
Try this lib:
https://github.com/bramstein/xsltjson
Looks very nice.
Its a 2.0 XSLT solution, although he also points to 1.0 version.
XSLT has many strengths and a few big weaknesses. Text processing is its weakness at least version 1.0
Although it would be technically possible to process that text with XSLT 1.0, I can't think of any situation where it would be a very good idea, and where it wouldn't be a very fragile conversion. The code you would have to produce would be very unwieldy.
Is there no other language available to you to do the processing?
I have a set of XML data that I'm trying to go through and determine how many items have a date of less than 1 week old.
DATA:
<events>
<event>
<eventDate>20110504</date>
<description>whatever</description>
</event>
<event>
<eventDate>20110720</date>
<description>whatever</description>
</event>
.
.
.
<event>
<eventDate>20111210</date>
<description>whatever</description>
</event>
</events>

I know that I can't change the value of a variable in XSLT since they are actually constants.
I know that I need to use recursion of some sort.
I just can't figure out how to do this... I am truly stumped.
Could someone please help?
Couldn't you determine the string value of a "one week ago" date, then do a textual comparison using XPath?
count(string(event/eventDate) > $oneweekagodatestring)
Replace in your code this:
L o n g C o d e
**** Increment a counter variable ****
$counter++
with:
<xsl:variable name="vHits">
L o n g C o d e
<!-- If the condition is true -->
<xsl:text>1</xsl:text>
</xsl:variable>
and this code:
**** Check the counter variable ****
<xsl:if test="($counter = 0)">
<p>No upcoming events are scheduled at this time.</p>
</xsl:if>
with:
<xsl:if test="(string-length($vHits = 0)">
<p>No upcoming events are scheduled at this time.</p>
</xsl:if>
Complete code example:
This transformation demonstrates "counter-less" computing with XSLT :)
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:strip-space elements="*"/>
<xsl:template match="/*">
<xsl:variable name="vHits">
<xsl:apply-templates/>
</xsl:variable>
<xsl:value-of select="string-length($vHits)"/>
<xsl:text> numbers fulfil x^2 <= 10</xsl:text>
</xsl:template>
<xsl:template match="num">
<xsl:if test="not(. * . > 10)">1</xsl:if>
</xsl:template>
</xsl:stylesheet>
When applied on this XML document:
<nums>
<num>01</num>
<num>02</num>
<num>03</num>
<num>04</num>
<num>05</num>
<num>06</num>
<num>07</num>
<num>08</num>
<num>09</num>
<num>10</num>
</nums>
the wanted, correct result is produced:
3 numbers fulfil x^2 <= 10
If you are using Sitecore you can always use some of the built-in date functions to get year,month and day out without resorting to processing substrings etc.
<xsl:variable name="selectedDate">20111212</xsl:variable>
<xsl:variable name="isoSelectedDate" select="date:ToIsoDate(date:ParseDateTime($selectedDate,date:IsoDateToDateTime(sc:isoNow())))"/>
<xsl:variable name="day" select="sc:day($isoSelectedDate)"/>
<xsl:variable name="month" select="sc:month($isoSelectedDate)"/>
<xsl:variable name="year" select="sc:year($isoSelectedDate)"/>
I think Dimitre's answer works well but this may increase the readability slightly :)
I ended up using the "one week ago" date suggestion. It took quite a bit of work to come up with the template to create the variable for "$oneweekagodatestring". However, I got it working:
