Increment a variable in for-each loop

No can do.

XSLT is a declarative programming language. You can bind a value to a variable only once, you cannot change it later. <link>

Search by Element and print RANum and position()

XML:

<InvoiceAdj>
  <RAInfo RANumType="79">
     <RANum>RANumType_79</RANum>
  </RAInfo>
  <RAInfo RANumType="82">
     <RANum>RANumType_82</RANum>
  </RAInfo>
  <RAInfo RANumType="85">
     <RANum>RANumType_85</RANum>
  </RAInfo>
  <RAInfo RANumType="88">
     <RANum>RANumType_88</RANum>
  </RAInfo>
  <RAInfo RANumType="79">
     <RANum>RANumType_79_1</RANum>
  </RAInfo>
  <RAInfo RANumType="82">
     <RANum>RANumType_82_1</RANum>
  </RAInfo>
  <RAInfo RANumType="85">
     <RANum>RANumType_85_1</RANum>
  </RAInfo>
  <RAInfo RANumType="88">
     <RANum>RANumType_88_1</RANum>
  </RAInfo>
</InvoiceAdj>

XSLT: Search by attribute RANum = 'RANumType_88'

<xsl:for-each select="InvoiceAdj/RAInfo">
<xsl:choose>
  <xsl:when test="RANum = 'RANumType_88'">
    <tr>
      <td><xsl:value-of select="RANum"/></td>
      <td><xsl:value-of select="position()"/></td>
      <td></td>
    </tr>
  </xsl:when>
</xsl:choose>                
</xsl:for-each>

HTML:

<tr>
<td>RANumType_88</td>
<td>4</td>
<td></td>
</tr>

Search by Attribute and print RANum and position()

XML:

<InvoiceAdj>
<RAInfo RANumType="79">
   <RANum>RANumType_79</RANum>
</RAInfo>
<RAInfo RANumType="82">
   <RANum>RANumType_82</RANum>
</RAInfo>
<RAInfo RANumType="85">
   <RANum>RANumType_85</RANum>
</RAInfo>
<RAInfo RANumType="88">
   <RANum>RANumType_88</RANum>
</RAInfo>
<RAInfo RANumType="79">
   <RANum>RANumType_79_1</RANum>
</RAInfo>
<RAInfo RANumType="82">
   <RANum>RANumType_82_1</RANum>
</RAInfo>
<RAInfo RANumType="85">
   <RANum>RANumType_85_1</RANum>
</RAInfo>
<RAInfo RANumType="88">
   <RANum>RANumType_88_1</RANum>
</RAInfo>
</InvoiceAdj>

XSLT: Search by attribute RANumType = 79 or 88

<xsl:for-each select="InvoiceAdj/RAInfo">
<xsl:choose>
<xsl:when test="@RANumType = 79 or @RANumType = 88">
  <tr>
    <td><xsl:value-of select="RANum"/></td>
    <td><xsl:value-of select="position()"/></td>
    <td></td>
  </tr>
</xsl:when>
</xsl:choose>      
</xsl:for-each>

HTML:

<tr>
<td>RANumType_79</td>
<td>1</td>
<td></td>
</tr>
<tr>
<td>RANumType_88</td>
<td>4</td>
<td></td>
</tr>
<tr>
<td>RANumType_79_1</td>
<td>5</td>
<td></td>
</tr>
<tr>
<td>RANumType_88_1</td>
<td>8</td>
<td></td>
</tr>

xsl:for-each sample:

xml: <InvoiceAdj AdjType="CS" AdjNumType="BP">

1. <xsl:for-each select="InvoiceAdj">

2. <xsl:for-each select="InvoiceAdj[@AdjType='CS']">

3. <xsl:for-each select="InvoiceAdj[@AdjType='CS' and @AdjNumType = 'BP']">

Legal filter operators are:

1. =  (equal)
2. != (not equal)
3. &lt; less than
4. &gt; greater than
